Thanks for your vid. I have recently purchased a Rancilio and have been binging all the vids I can find on dialing it in. Your explanations and examples are so clear and easy to follow. Thanks for the time you put into this, it has made my experience a much easier and much less scary one! And oh, the coffee is so freaking good!

[@LemLTay]

Thanks for being so generous with information and tips, Marc (WLL)! I'd simply echo all the points you've made, where my espresso journey has been on a similar path. After the much-lauded Breville Oracle came out a few years back, it set me thinking of what I could do to control each element of my shots to simulate what is being done through the latest technology and lots of electronics. Through a process of trial & error, reading up other experts' tips and learning from forums, I've come up with my own "formula" for my set-up. I've an old-school Brugnetti Simona Top DE (with volumetric controls), a single-boiler HX system. It's really old-school, with Brasilia handles & standard 58mm basket, 1.2L boiler. It's simple and basic, but the rock-solid build has meant it has lasted since it was purchased in 2004! Even today, it works like when it was bought over a decade ago, has only had the occasional servicing / descaling, plus the usual gasket change (when the shots starts leaking around the grouphead). The "worst" repair needed thus far was the rocker on-off power switch that took a little longer as I wanted the original illuminated green colour, as the most common spare parts are illuminated red ones. 1) Temperature. Allowing the machine sufficient time to heat up, making sure there's no "false pressure" in the tank. Checking that the boiler gauge settles in at 1.3 bar. Prior to each shot, heat-flush the grouphead till the boiler light comes on, lock in filled portafilter, wait till the boiler reheats (few seconds), then start the shot. 2) Grind. After I bought the machine which at that time seemed quite pricey, I felt reluctant to shell out for a decent grinder and nothing worked right for the first month! Totally undrinkable drek! Finally stumped up for a Mazzer Mini and it's been good ever since ("it's the grinder, stupid", as they say!). The gauge is around the 5.0 to 5.1 range on its dial for me, and I know that's the starting point to tweak the settings slightly depending on freshness of the roast. If I've guests who might be nosy, I even unscrew the adjusting pin from the grind adjustment ring and hide it, so that no-one fiddles with it! One thing I've found, if I want to grind coffee separately for drip / pourover, I use a different grinder as turning the dial up and down just makes a mess for finely-tuned settings required for espresso shots. 3) Tamping pressure. Always my inconsistent factor, despite practicing on weighing scales. An easy thing to fix with a spring-loaded tamper, a relatively easy and inexpensive thing to purchase for a 58mm basket. No longer an issue at all! 4) Dosing. I weigh out 16g for each double shot on my scales, then grind the lot and use it all, flicking the dosing lever repeatedly until the chamber is cleared. If multiple shots are needed, I just line up a few more saucerfuls to grind and dose subsequently. It's not as efficient a process, but the advantage is the coffee is used entirely and nothing is left in the hopper or dosing chamber overnight either. 5) Shot volume. With the pre-programmed volumetric buttons, that's an automatic process to get the right shot volume each time. So overall, given the manual limitations of my set-up and some low-tech tweaks, my coffee has been a lot more consistent over the past two years or so by locking in the variables. That said, there's still the "human factor" in making coffee, and for me, the biggest factor is inattention of any kind (aka not being "in the zone"). If one isn't concentrating on the process, a screw-up can easily happen and the shot is ruined. For example, a simple oversight of not filling the water reservoir before the brewing session begins and halfway through the shot, water runs out. Game over, red rover!! PS: Yes, making the coffee with a manual set-up needs attention, but my machine has well outlasted many friends' fancy-pants superautomatics. I recently bumped into one friend who related the sad tale of how his expensive European-branded superautomatic that only lasted a few months, where it was left to a house-minder to use, and the machine broke down irretrievably and couldn't be fixed after that.

[@Wholelattelovepage]

Hi Lem, Thank you for sharing the details of your journey! Think you just won the award for longest comment of the year! Can't tell you how many times I've run out of water in reservoir fed machines. I plumbed my daily use machine - a Profitec Pro 700 in the studio earlier this year and love it. One less thing I have to think about. And it gave me the option of doing long low pressure pre-infusion as plumbed Profitec machines have no solenoid valve on the waterline connection. Installed a BWT filter system which has a pressure regulator so I can dial in different pre-infusion pressures and never worry about descaling again!

[@padraicmcgross82]

Super helpful video. Thanks Mark! Took some power to put on the filter holder on my Gaggia New Classic but I got the right grind size and it took 30 secs.

[@pascalgolay1160]

Thanks for this - I use an Oscar 2 - the pours have always been very fast ~ 5-6 seconds, even with quite a fine espresso grind - I've recently made the grind even finer - to the point where the grounds starts to clump up as they come out - that has slowed things, and made for some increased flavor, but a pull is still only maybe 10-12 seconds.

[@Wholelattelovepage]

Hi PG, What make/model grinder are you using? 10-12 is far too fast. If using a lower cost grinder it's not unusual to get clumpy grinds at espresso fine grind sizes. After the beans, grind quality is the most important factor in making a good espresso. Old recommendation was budget 50% of machine cost for your grinder. Quality grinders have come down in price over the years. Check out our video on top 5 best coffee grinders. We have a category in there for Best Value for Home Use. Our pick in that category is the Baratza Sette 270. It produces beautiful clump free grind at espresso sizes. Here's a link to that video: kzbin.info/www/bejne/g56UhXmgd7BrecU Marc

[@kenmitchell3355]

My portafilter is often hard to turn but sometimes easy. Does this matter? I have a Breville Barista Touch. Great video Mark!

[@Wholelattelovepage]

Hi Ken, Thanks for the kind comment. Portafilters can become difficulty to clock in for a number of reasons. A common one is accumulation of coffee debris in the group head. Try and clean that area on a regular basis. Also, group head gaskets which form the seal with the portafilter are a wear item and need to be replaced from time to time. They stiffen with age. Hope that helps! Marc

[@savannahstover2915]

this was so helpful! how do you know what grind size to ask for when getting beans ground at the bean roasters?? our shots are pulling too fast but don’t want it to be too fine. it’s hard when we don’t yet have our own grinder to trial and error!

[@Wholelattelovepage]

Hi. SS, Thanks for the comment and question. It's going to be nearly impossible to get espresso grind size right if someone else is grinding beans for you in advance. Maybe your roaster has told you that? Very small changes in grind size make a big difference when making espresso and there's no way your particular brewing variables will match someone else's. Even as beans age, grind size needs slight adjustment. Then there's the loss of freshness from grinding ahead of time. Until you have your own grinder there are some things you can do. If shots are coming too fast increase the amount of coffee in your filter basket to slow down the extraction. For this to work you need to be relatively close to optimal grind size. You can also try tamping the coffee harder which should have a slight effect up to a point. Another option is to use a pressurized filter basket. In a pressurized basket the basket is mainly responsible for creating the restriction to create pressure. Pressurized baskets do compromise espresso quality. Hope that helps! Marc

​@@classicrockonly A couple questions for you and a story! What grinder do you use for your Flair? Favorite classic rock band? What was the last full classic rock album you listened to? Mine was Aerosmith Live Bootleg - thought that was appropriate for a road trip to Boston! The story: I was at SCA Expo in Boston a couple of weeks ago and stopped by the Flair booth. Flair Espresso Director of Support and Social Andrew Pernicano pulled some shots on the Signature Pro for me - good stuff! and it was cool meeting him. I had never met him before, but he recognized me from our videos. I really like the Signature Pro! So much we will likely be carrying them. It fits nicely has a higher-end option to the ROK Maker we have now. Marc

[@classicrockonly]

@@Wholelattelovepage Right now I just use a Baratza Encore, and it does the job :) Though I know a lot of the folks on the Flair Facebook group would disagree and suggest a Sete 270 at a minimum hehe. My favorite album...that's a great question! I'd have to say Boston's first album, I could listen to it constantly :) Which is funny since you mention a trip to Boston. I have to say I haven't heard that live album, but looking at the tracks, those are also some of my favorite songs. That's cool you got to meet Andrew. I haven't met any of the folks at Flair but they're super friendly and helpful on the Facebook group and the product sure is great, and I'm glad you liked it too!

Isn't it best to weigh the shot as you pull it rather than go on volume? For example if I dose 18g my end result out should be 36g in 25-30 seconds I.e. 1:2 ratio. Great video btw also what's the name of the grinder you use?

[@ssjoebear]

Hi, WLL. I bought a refurbished Gaggia Classic from you guys and so far it's been great. The only issue we are having is getting the 58mm portafilter into the group head without a struggle . It just seems way too difficult. Is our grind depth in the filter too high after tamping? We need to get a better tamper (than the plastic one it comes with), but aside from that, any other tips?

[@Wholelattelovepage]

Hi Joe, Please excuse my delayed response. I've been on the road for a few days researching new machines! Refurbed Classics are a great deal - and thank you for the purchase. It may be your fill in the filter basket is too high. If the shower screen is leaving a mark in the coffee puck after brewing then you're dosing too much. Other tips: Clean the group where the PF locks in. Coffee can accumulate making it more difficult to clock-in. A bit of leverage is typically required to lock-in place. Check to see that the group gasket is fully seated. It should be and locking in the PF generally pushes it into place if it is not. Also, if you can swing it when you upgrade from the plastic tamper consider going beyond tampers to a leveler instead. They are far more consistent in coffee distribution in the PF and making a parallel surface on the puck. Those both help to prevent channeling thru the puck and produce more consistent shots than tamping. If not familiar with levelers here's a video on my favorite: kzbin.info/www/bejne/aouYp4efa5lmqcU Hope that helps, Marc

[@ssjoebear]

@@Wholelattelovepage - Marc, thanks so much for the reply. Great tips. I do think we'll go with a leveler instead of a tamper. And I'll be sure to give the groves where the PF locks in a good cleaning. Appreciate the feedback. Cheers.

[@davidhorner9256]

Thanks Marc for the quick response. Much appreciated. I’m still trying to figure out this whole process. My coffee produces a lot of crema so the actual liquids volume would be less. Should I be altering my grind or other variables?

[@Wholelattelovepage]

Hi David, You are welcome. It's tough to do brew ratios using liquid volumes. When using a coffee which produces a lot of crema I'm often hitting liquid volumes of 65-70ml including the crema from an 18g ground coffee dose. Although reaching 65-70ml the weight in cup is ~36g as crema weighs far less than liquid espresso. Only accurate way to do brew ratios is with an accurate scale under the cup while extracting a shot. Marc

[@mathanmachlev]

Thank you for the wonderful knowledge! Questions: Let's say I'm putting out water temperture (consistant) and dose weight. Now you get grind size, brew time, and brew ratio (or volume?)/ 1. Volume of liquid or weight? I understand usually the measurement is brew ratio, which refers to weight - question is wether there's a significant difference between 36 ml shot to 36 g shot? If so, does the grind size affect the final weight of the shot? Do you measure it at all or eventually it's fine to stick with the volume only? 2. How do you determine the time and volume/brew ratio? Do you at first just fix an arbitrary ratios like 60ml to 17g dose, 25 sec, then play with the grind until you get there? Now you found it, which changes do you make in order to idealize it more - keep grind size and change the volume or keep volume and change grind size (therefore time)?

[@Wholelattelovepage]

Hi mm, Great timing for your question! Put up this video yesterday on Brew Ratio: kzbin.info/www/bejne/a2i4ooN6ntd7pbc Your questions: 1. Brew ratio is measuring weight. There usually is a significant difference in volume v. weight. A thick layer of crema weighs less than espresso in full liquid state. In the video linked above I pull a shot that ends at 60ml/2oz volume and it weighs about 42g. Grind size can affect final weight but it's relative to volume of water thru the shot. A finer grind makes for a shot with more dissolved solids. For coffees I work with a lot I don't weigh very often. I know them well and can tell if something is off by appearance. 2. In general you keep the time the same regardless of the ratio you are shooting for. So same timing for a 1:1 ristretto as a 1:4 lungo. You can manipulate grind and dose in tandem to end with the same timing. In general decreasing dose makes a shot less bold while you'd also use a finer grind which makes the shot less bright. Going the other way a coarser grind with a higher dose makes a shot less bitter and more bold.

Around minute 5:46 you mention that the Profitek Pro 500 does best with a short flush before brewing - is this also true for the PID version of this same machine?

[@Wholelattelovepage]

Hi Paul, Thanks for the question. Before PID use in HX boiler machines a cooling flush was standard procedure. Today's HX machines with PID like the Pro 500 generally do not need a cooling flush unless the machine has been sitting idle for an extended period or one is running the boiler hotter than normal to increase the steam power.

I have been for last 2 weeks trying to get a perfect espresso Crema shot using home espresso machine..I don't think I can achieve a perfect shot the way I see in Ur video..and ofcourse I am just a home Barista not a pro to buy or afford a costly machine.i use hand burr mill grinder.. Morphy Richards fressco 800 watts machine..the pressure as predicted is 15 bar..but still can't get it right..

[@Wholelattelovepage]

Hi PP, After the bean, grind is most important to making an espresso. What make/model hand grinder are you using? There are some good ones but many lower cost hand grinders have wobbly shafts and lower quality burrs. Wobbly shafts allow the spacing between the grinding burrs to change while grinding. With that the grind they produce tends towards an inconsistent coffee particle size.

Hi sidd, You are welcome. Thanks for the first comment!

[@TR-fg9hb]

Very helpful video. Thanks. When using a single shot portafilter do I cut the time in half? If 25 seconds does 2 oz of liquid (for the double) would 12-13 seconds give me a 1 oz single? I worry that would not give the same flavor.

[@Wholelattelovepage]

Hi Jeff, Keep in mind timing is the most basic method for determining when to cut a shot. That said if using timing it should be about the same for a single and a double. A single basket has far fewer holes than a double basket so that increase the time. The same pressure produces a lower flow rate. In the end it's about how much water went thru the coffee. With a similar contact time flavor should be about the same when doing a single or a double. PS. Singles are much more difficult to do than doubles! Marc

[@pkerry12]

I always have 20 grams of coffee with a 38g shot for a 1:1.8 ratio works well all i need to do is keep dialing in the grind till its perfect, i use a distributor and tamp combo device to get the perfect and the same tamp every time its adjusted to the rigjt depth.

[@Wholelattelovepage]

Hi PKTV, Thanks for sharing your parameters! Sounds great!!! Marc

[@vantagedriver6477]

Should the measured volume include the crema as appears in this video, or should it be liquid only rather than liquid and foam?

[@Wholelattelovepage]

Hi VD, Thanks for the question. If using liquid volume you will need to estimate. Most coffees producing moderate crema will reach a liquid volume of ~2oz/60ml at the end of a double shot made from 17-18g dose and result in a standard espresso brew ratio of 1:2. For more accuracy weigh your coffee dose and espresso as it extracts. For and 18g coffee dose you'd stop the extraction when it weighs 36g for a 1:2 ratio. Marc

[@Yggdrasil42]

Hi Uzair, Wow, good memory we did do a dial in video a year or two ago. This one was a bit more focused. Kept it basic and beginner level. Will see what we can do about getting a fine vs. coarse comparison on the Ceado. In the meantime, what are your concerns with grind range on the Ceado? Are you looking to do Turkish grind? I can say the Ceado will do a coarse grind but it's really more of an espresso specialist. Depending on how particular your are this type of grinder is probably not the best choice for coarse grind - also a real pain to use this type of a grinder if you're making large changes in grind size on a regular basis.

Love your videos. They are so helpful. i just purchased a new Breville Barista Express. Running Columbia beans (fresh) at #5. 16.5G in the porta filter. How many grams of finished coffee should i get with 16.5G of grind? My coffee seems to be running bitter. My brew time is about 26 seconds. and throwing 2.5oz of coffee (probably too much) Thoughts?

[@Wholelattelovepage]

Hi Paul, Thanks for the comment and question. Bitter indicates over-extraction. Typical brew ratio for espresso is 1:2. So using 16.5g grinds you're looking for 33g out by weight. Using volume to get brew ratio is tricky! I've done 1:2 ratio with crema producing coffees like Italian style bean blends and volume in cup including crema is 60-70ml. On the other hand single origin specialty coffees with far less crema might end at 1:2 ratio with 40ml in cup from 19g dose. I think you are right with the probably too much volume at 2.5oz but depends on how much of that is crema. Marc

Great video thanks! Do I need to pre flush for an Expobar Brewtus IV? Thanks!!

[@Wholelattelovepage]

Hi Mike, You are welcome! In general you should not need to flush a dual boiler Brewtus. Can always check for flash boiling by running a bit of water from group without a Portafilter in place. If you see lot's of bubbling and/or turbulent flow from the shower screen that calms down after a few seconds that's flash boiling and you don't want that hitting your coffee. Most likely to happen if you are running at the high end of espresso brew temps or the machine has been sitting idle but on for long periods i a warmer than usual environment. Marc

[@joseberrios8171]

Hi, great video! I am using an old Gaggia Clasic and Breville the Smart Grinder Pro and great coffee beans producing delicious crema. Any suggestion on how to control the temperature for brewing due to the lack of a thermometer in the Classic getting inconsistencies in the final shots. Sometimes too quick running water and too fast the brewing.

[@Wholelattelovepage]

Hey Jose, Thanks for the comment and question. Like all machines controlled by themostats or presurestats there is some variance in boiler water temps depending on where the machine is in its heating cycle. One tactic with the Classic is to flush water from the group head until the brew ready light goes out. Then wait until the brew ready light comes back on and pull your shot then. If you want brew water hotter wait say 20 seconds after the light comes on. If cooler do a short flush of 3-5 seconds prior to extractions. Marc

[@SirOreo62]

Great video for those of us learning the ropes with these premium espresso machines. One unrelated question triggered by the 1 bar pressure comment and gauge view at the beginning of the video for those of newbies. Should the pressure in the boiler be totally emptied when turning off the machine, does it matter?

[@Wholelattelovepage]

Hi C, Thanks for the question. No need to release the pressure. It dissipates on its own as the machine cools down. Once below boiling point a vacuum relief valve opens on the boiler to ambient pressure. Marc

Hi mark, I new in espresso machine. But I not sure what is the golden rule to adjust grinder for espresso. Could you advise on the golden rule for grind setting for espresso? What I set if I taste sour or bitter? Will there be chance that I do not have sour or bitter? Sour means acidic am I right?

[@Wholelattelovepage]

Hi BW, Thanks for the questions. Golden rule is adjusting your grind size such that your extraction (regardless of ground coffee dose weight) comes in 20-30 seconds. In general, sour flavor indicates an extraction that came too fast = under-extraction and bitter flavors an extraction that's to slow = over-extraction. Sour flavors might be described as bright. Marc

[@Wholelattelovepage]

Hi Madison, Thanks for the kind comment and question. Like all non-PID single boiler machines the GCP does swing in temps a bit depending on where it is in heating cycle. You can sort of see the heating cycle as the brew ready light will turn on and off. When the brew ready light comes on the machine is very close to its max internal boiler temp. When it turns off it's at its low temp point in the boiler. You can do a short flush and look for flash boiling of the flushed water at the group/shower screen. Flash boiling is indicated by extra turbulent flow. If you see that flush until flow is smooth. Should only take a few seconds to get smooth flow then you are ready to brew. If no turbulaence then no need for more flushing. You'll get used to when it needs flushing by associating the brew ready light to what you see when checking for flash boiling. Once you get used to it you'll know when you need to flush. Tip: Keep your PF in the group when machine is idle. Keeps it warm and bleeds off heat from the boiler potentially reducing the need for those short flushes. Hope that helps! Marc

[@Wholelattelovepage]

Hi KK, Thank you for the question and comment. Your appliance appears to be one which uses a pressurized filter basket. These allow okay results when using pre-ground coffee or ESE pods. They are not capable of the same espresso quality as machine grade products with standard non-pressurized filter baskets working with coffee ground fresh right before an extraction. That said, my advice for better results: Use a good coffee with a grind size appropriate for making espresso. Load the portafilter with as much coffee as possible, make sure the machine is warmed up before use as this type of machine is not great at providing a proper brew temp. Can help to run some brew water thru the portafilter with no coffee loaded to help warm it and other brewing components up right before making an espresso. Marc

[@hobbygrg-eudaimoniastudio]

Hi Mark. Enjoyed the video. A pint of clarification. When you refer to a two ounce shot are you talking about the liquid only or the total volume including the crema?

[@Wholelattelovepage]

Hi David, Thanks for the comment and question. 2oz/60ml would include the crema. If using a coffee that does not produce a lot of crema then volume would be less. Marc

[@ProfessorJones7]

I see a lot of people say that you should time shots from the moment you turn the pump on, not the first drip. That makes sense to me because extraction starts as soon as water hits the puck. Still, I'm confused about which method I should be using...

[@Wholelattelovepage]

ProfessorJones7 thanks for the question. I’ve chosen to go with first drip. Vibe pumps are slower to build pressure than rotary machines, sometimes pre-infuse... working different machines and methods one constant is 1st drip

[@ProfessorJones7]

[@RB-nv4lo]

Hi, so I have the barista touch, and was just wondering I do 18g and use the 1:2 ratio in 25-30 seconds. Is this incorrect then? And should I be always trying to get 2oz (55-60g). I’m new and I’m using a dark roast espresso blend and my coffee is always bitter, but I’m gonna change the beans

[@Wholelattelovepage]

Hi RB, Thanks for the question. Are you weighing the output or using liquid volume to arrive at 1:2 ratio? If weighing output then 18g in, 36g out in 25-30 seconds is a good place to start. If using liquid volume it all depends on how much of that volume is crema as the crema is much lighter than the full liquid espresso. If about half of you extraction is crema when you stop then 60ml is about right for a 1:2 ratio. If 60ml of all liquid then you're way over the 1:2 ratio - maybe at 1:3. Bitter flavor indicates over-extraction but could be inherent in the dark roast you are using. Dark roasts tend to do better with lower brew water temp - at cooler temp you'll extract less of the undesirable flavors. Might also try cutting the shot sooner to reduce bitter flavor. Hope that helps! Marc

[@johnvandervelde2332]

I just bought a ECM casa v from y'all. Do I need to flush prior to each shot?

[@Wholelattelovepage]

Hi John, Thanks for your patronage! Flushing depends on where the machine is in its heating cycle, how long since the last extraction and other more minor factors like ambient temps. The easy check is a very short flush and look for turbulent flow off the shower screen. If not turbulent your good to go right away. If it is, flush a few seconds more to smooth flow and you’re set. Do keep your portafilter in the group when not in use to keep it warm and act as a heat sink to smooth boiler temp fluctuations. After using for awhile you’ll get an idea of how to work it for good temps. Hope that helps and enjoy! Marc

Breville infusion here had it here for well over three years always used to pressurize porta filters every once in a while I'll pull out the non-pressurized and try as hard as I can to get it to work wasting tons of coffee to get it to be like the pressurized Crema and it just won't happen . The pressurize baskets are a hit and miss some days have decent shots other days well . I'm not sure if the Breville is just inconsistent on shots or if it's possibly the Breville pro grinder not always putting the same amount of grounds each time or maybe not consistent with the grind or just the combo of the two together . The only decent looking Crema I can get it set at 19 to 20 on the grind . Is it even possible with the non-pressurized porta filter and Breville pro grinder to even get a decent shot non-pressurized

[@rvandenburg8360]

Hi Mark, Question for you...So I've recently transitioned from a Breville Duo-Temp Pro to a Breville Infuser. I was Quite happy with the Duo-Temp Pro's espresso. I found everything didn't have to be SO DARN PRECISE to get a great shot pull!! I 'think' what my problem may be is the brew temp on the infuser is too high. Often my shot pulls are bitter even when dialing it down....I even went as far as to purchase the Breville Smart Grinder Pro. Because I was having such a problem with bitterness....what I did notice from the get go, in using the Infuser was the temp. was HOT. (Glass too hot to hold Hot!!) CAN that be adjusted??? Also one more Quick question....Can I Pull more than 2 shots at a time with the Infuser.....I do 6 shots and frothed milk. With the Breville Duo Temp it was NO problem. Thanks I enjoy watching Whole Latte Love videos!

[@Wholelattelovepage]

Hi RV, Thanks for the question and kind comment. To the best of my knowledge brew temp is not adjustable on these machines. I do believe there was an upgrade to the thermoblock boiler in the Infuser model. It's possible the Duo-Temp was under temp and now with the infuser working at higher temp you're getting flavor different than you were with the same coffee on the older machine. Typical corrections for bitter flavor are: Coarser grind, lower coffee dose and lower brew temp. Sounds like you've tried working with grind. As your temp is not adjustable you could try running some water (cooling flush) without the PF in place right before pulling a shot. This might cool it down but it could also make it hotter. Cooling flushes are more common on older heat exchange machines without PID. I'm not sure what happens in machines with a thermoblock boiler like yours. Hope that helps! Marc

[@Wholelattelovepage]

Hi Cole, We've done Scace testing on Rocket's EVO R and Type V Mozzafiatto and Giotto machines as well as Profitec's Pro 500 PID. All are PID HX boiler machines. Our Scace tests show these machines provide very accurate brew temps without the need for a cooling flush. The manufacturers have engineered the E61 thermosiphons with flow rates which prevent overheating of the brew water section of the HX boiler. Just to be clear, other (typically older) HX machines with pressurstat temperature control generally need a cooling flush prior to brewing. Marc

Hi Marc, Great videos, I've watching you lately. I just got a Breville BES870XL a month ago, also I've had a Capresso Infinity Burr Grinder for some time (We've used it for French Press). Some questions: 1.- I use the grinder in my Breville, should I do this or try to use the Capresso Infinity instead for my espresso shots?. Which one would give me better results? not planning to upgrade grinder, I want to work with what I have. 2.- Very Specific to the Breville BES870XL - How many double shots of espresso can you make in a row with this machine? I heard that you can only make a few and then let the machine rest. 3.- I froth the milk before my espresso, should I flush the head right before the shot or flush and wait some time and do my shot? 4.- Should I start the timing the espresso with pre-infusion or as soon as the first drop drips? I only use the double shot single wall portafilter. I'm using 18 grams of beams. Thanks in advance!

[@Wholelattelovepage]

Hi AM, Thank you for the comment and questions! 1. The grinder in your machine should give better results than the Capresso Infinity. It has finer control of grind size in the espresso grinding range. 2. The machine uses a thermoblock boiler under PID control so brew temps are accurate shot to shot. When you do many shots back to back it's possible components like the group head can heat up. But, I wouldn't worry too much about that. You'd really have to be cranking them out continuously for that to become an issue. 3. Flushing is not required after steaming. The machine automatically purges excess steam after frothing. 4. I prefer timing from 1st drip. That way things like pre-infusion do not become part of the timing. Timing shots is a basic technique and works as a guide to get you in the ballpark. In the end, I'd go with flavor. Some coffees to better with longer or shorter extractions and other variables like grind size and dosing weight play into the finished espresso. If you want to go further check out our video on brew ratios. Using brew ratios requires a scale capable of weighing an extraction in real time. Here that video: kzbin.info/www/bejne/a2i4ooN6ntd7pbc I like the double shot non-pressurized (Breville's single wall) basket with 18g doses - exactly what I would use! Hope that helps.

Hi! I know this video is old but wondering if you can help me dial in with a mazzer super jolly grinder and Astoria Pratic Avant. I just started at a cafe and though I have some espresso experience, it’s not much or enough to troubleshoot this. I’ve done all the little tests I know to do. I have the grinder set as fine as it goes and the coffee just doesn’t seem like it’s right it feels dry and light with no oil. Doesn’t compact in my hand at all, falls apart immediately. It extracts 2oz in 15 seconds and they are light, watery, have no body or flavor and no crema…could the coffee just be too old?? Could the machine be putting out too much water?

[@Wholelattelovepage]

Hi Allie, Hmmm.... 2oz in 15 is of course too fast. You should be able to grind fine enough on the Mazzer to choke the machine - meaning you'd have very little or no drips when pulling a shot. I suspect your grind is not fine enough. Even old coffee ground fine enough should choke the machine. You might try opening up the grinder and cleaning. Mazzers can be a pain as the fine threads are exposed to coffee in the grinding chamber. Threads can get gunked up and make it difficult to adjust the grind size - es[recially when adjusting to a finer setting. Should you clean the grinder make sure the threads are spotless. You may need a needle (and some patience) to thoroughly clean the threads so they don't bind when adjusting to a finer setting. Hope that helps! Marc

I have a classic old hand-pull Olympia Cremina. Your video shows a grind for a 20-30 second pull, but they appear to be automatic. When I first put my portafilter in it has a pretty steady drip but not a stream. At what point should I start my pull? And should I try to time it for 20-30 seconds?

[@Wholelattelovepage]

Hi l, Thanks for the question. When using a manual lever machine timing can be a little different. You have some pre-infusion happening with the initial set of the lever prior to release. I generally do not count that time in an extraction. Understand timing is the most basic method of appraising extraction. Useful for initial dial in of grind size. After that, let flavor be your guide. If bitter, increase grind size a bit. If sour decrease grind size. Hope that helps! Marc

Hi guys, why exactly is a double shot easier to pull than a single shot? Is it because the weight range is broader, giving you more play with dosage?

[@hankveenstra4329]

Hi there. I use a breville dual boiler and a la pavoni grinder. At its finest setting I am able to get the grind size small enough that it clumps up. However, even at this size I struggle to get my shots to pull at the desired pressure / time without using one of the pressurized filters. Do I need a better grinder to get the grind even finer? My machine is freshly descaled and cleaned. Thanks in advance for your time, Hank

[@hankveenstra4329]

By struggle, I mean that I have to put so much espresso in that I am tamping with a ton of pressure and have to push the portafilter hard into place. I can brew a good espresso this way, but it seems more physically challenging than it should. It should be noted that I almost exclusively brew single shots. I haven’t tested the unpressurized double shot filter in a long time.

[@Wholelattelovepage]

Hi hank, Thanks for the question. It sure sounds like your grind is not fine enough. But that grinder should be able to go fine enough to choke your machine. I would for sure try the unpressurized filter basket. You mentioned your grind clumps up which typically indicates a very fine grind. But, some grinders may produce a clumpy grind even at a grind size coarser than that needed for espresso. This can be caused by extra oily beans, obstructions in the grind delivery chute or just be the grinder. It's been a long time since I've used a La Pavoni grinder so I don't recall it's characteristics as to clumping. Marc

[@reuvenansh5231]

I noticed at 5:56-6:00 during pre-flush that there is clearly a stronger water flow in the center and back right, i.e. it's not perfectly even. Same thing happens in my Gaggia Baby Class. Technically the water comes from 2 larger holes and spreads into 6 smaller holes in a circle before going through the filter screen. So I'm sure that's why it's not really even; so how does that affect how evenly the water goes through the beans and the final extraction? Does it actually spread out better when it reaches the bean surface? Great video, as always -- thx!!!

[@Wholelattelovepage]

Hi RA, Thanks for the question. Some machines provide a better more even flow from the shower screen than others. Uneven flow can have an affect especially if the filter basket is too full so water is forced directly into specific areas of the coffee puck. If you are getting an impression of shower screen in puck after brewing then your basket has too much coffee in it. We do want some space between shower screen and coffee puck to allow for even saturation of the puck. Marc

[@reuvenansh5231]

@@Wholelattelovepage Great point, you're saying that having some space b/t the shower head and puck will usually allow for an even enough extraction. Just now viewed an interesting idea where an aeropress filter was trimmed and placed 1 above and 1 below the puck significantly increasing the TDS from around 9.5 to over 10 for a better extraction - although not really so practical.

As coffee gets older do you generally have to grind slightly finer or courser?

[@Wholelattelovepage]

Hi Sam, Thanks for the question. In general, as coffee ages one will need to grind finer for the same extraction rate. But I have experienced exceptions. We recently ran an experiment using an Ethiopian Yirgacheffe that was 4 days from roast. We dialed-in grind for a 25 second extraction and did one extraction per day for 30 days without changing grind size or coffee dose. For about 20 days extraction timing increased reaching about 50 seconds. Then timing started to decrease and around day 26 it returned to about 25 seconds. Marc

[@pip5461]

It looks like you're judging the amount of coffee out by the crema surface, but if you wait till the visible coffee reaches the line it would take longer. As crema differs, which is correct... "The crema level, or the liquid level" to reach the mark line... ?

[@Wholelattelovepage]

Hi Pip, Thanks for the question. This is a basic technique video. I'm assuming those watching are newer to espresso and do not have a scale capable of accurately measuring weight of espresso as it extracts. Without a scale, one must make an estimate. I'm using my experience to make that estimate and it's a good place to start for typical coffees and there crema production. More accurate method is using a capable scale to weigh the coffee dose and the espresso extracted. Typical espresso brew ratio is 1:2. Meaning weight of espresso out is double the weight of the ground coffee used. So 17g ground coffee produces 34g of espresso in 20-30 from first drip. Be aware one cannot translate liquid volumes to weights with accuracy. While pure water weighs 1g per 1 ml, Espresso does not - especially the airy crema which is much lighter.

Very informative video Marc. I have a Gaggia Classic. Should I be pre-flushing, and for how long? Any additional hints on using the Gaggia Classic? Thanks for your assistance.

[@Wholelattelovepage]

Hi Allen, Thanks for the comment and question! First thing to do is bookmark our support wiki for the Gaggia Classic: wiki.wholelattelove.com/Gaggia_Classic Loads of use and maintenance info in written and video form there. Also manuals, diagrams, etc. On flushing... answer is yes! There are many techniques for getting the Classic to proper brew temp. Single boiler machines like the Classic have dead bands in heating cycles. Boiler gets up to temperature and machine indicates it's ready to brew. Then temperature in boiler starts dropping until the drop is enough to kick the heating element back on. One technique is to flush the machine until the heating element comes on then stop flushing. Then wait until the machine indicates it's ready to brew and do so immediately. If nothing else, flush without the PF in place until water flow is smooth from the group with no indication of flash boiling/excessive steam. This should only take a few seconds but duration will vary based oin where the machine is in its heating cycle. Here's a video which explains dead bands and a technique for getting consistent brew temps. It's demo'd on a Rancilio Silvia but a similar technique can be used on the Gaggia Classic: wiki.wholelattelove.com/Gaggia_Classic Hope that helps, Marc

Hi d, Thanks for the question. Honestly I do not use a Silvia very often. I do know there's quite a bit of variation of in boiler temps depending on where the machine is in the heating cycle. That variation gets smoothed out a bit as water moves from boiler to the coffee. Personally I'd do a flush and watch/listen for flash boiling indicated by turbulent flow from the empty group and or hissing (steam). I'd flush until flow smooths out and then brew. Marc

I have the Quick Mill Anita evo. Flush required?
