You guys are working HARD to capture all this stuff! Thanks so much! This is one of my primary hangups actually and one that I'd like to try to tackle in the future. I always have a lot of light to medium roasts around and when pulled for espresso they rip my face off with acidity. For that reason I pull daily-driver espresso milk beverages with Red Bird which is a "classic profile" and save the 3rd wave stuff for pour over. I'd like to get to the point where I can tone down that acidity and this gives me good ideas. I'm using a Silvia with a MeCoffee PID which can dim the pump and result in a simulation of flow profiling (with preinfusion). So far I've been told to focus mainly on temperature (higher) which I can also do with the PID so now it's just a question of adding these other two variables into the mix. A followup video that addresses Temp, preinfusion, and flow profiling would of course be very welcome!

Hi Marc, incidentally I have started a bag of 'cheffe (11 days from roast) , just beans are smaller and more roasted than I see in your video. Beans are denser than Sumatra or Honduras, to say, and probably that's a reason why regular shot can be light and lack a bite (I've noticed it, and agree to you and Todd). As my machine doesn't change flow rate, I balance grind and time to have extraction longer than I'd use for other beans - yielding same amount (around 35 sec - similar to your 38 sec). I realise my results aren't same as with flow profiling (workaround instead of solution) but I can see use for this tech. Thanks for video! I hope ECM will do right w/ Puristika, it could be ticking most of boxes for me.

Hey MP, You are welcome! Americanos for sure. Changing flavor using flow in those will be very apparent. Let's say you have a dark roast coming off as too roasty or bitter. You could use a lower flow as the extraction progresses to reduce those flavors. In milk drinks the flavor difference is still there but maybe a little hidden. Depends on ratios. Very apparent in a short double shot flat white maybe not so much in a large single shot caffe latte. Depending on what you like you might even try to increase bitterness to balance the sweetness of the milk. Hope that helps! Marc

Hi Steven, Thanks for the comment. We will have more videos on using flow. A couple of general principles... As seen in this video: Long low flow pre-infusion for very fresh from roast specialty coffees to reduce acidity/brightness. For older coffee: Full flow to start then ramp it down as extraction progresses to avoid pulling out stale flavors. Coffee shots: Use a continuous extra low flow, medium (filter/drip) grind size with extraction time out to 60 seconds. Part of the fun with flow is trying different profiles with a particular coffee and taste the affect. Marc

@Wholelattelovepage2 жыл бұрын
Hi Josh, You're welcome for the video! Slower flow will affect medium and dark roasts as well. In most cases I tend to use a higher flow rate initially and reduce the rate as the extraction progresses for darker roasts. But if a coffee is relatively fresh from roast like within 3 weeks I'd try a low flow rate start. The low flow helps reduce brightness by allowing CO2 still locked up in the beans to off-gas prior to digging in to the extraction with a higher flow rate. Here's a video which simplifies that concept: kzbin.info/www/bejne/l160coKlbbuaa6M Marc

Hello wholelattelove, I still do not understand the difference between pressure profiling and flow rate control. From my understanding, pressure the pump generates affects the flow rate. So, if we make pressure profile, we also controlling the flow rate. Am I missing something here?
@Wholelattelovepage3 жыл бұрын
Hi HK, Pressure and flow are related but not the same. Imagine you are pulling a shot and the timing isn't quite right so you adjust the grind size. If you're pressure profiling the pressure will be the same with a new grind size but the flow rate will be different. If you're flow profiling in the same situation the flow rate stays the same with a change in grind size and the pressure will likely be similar. There's research showing little difference in dissolved solids in cup whether one extracts at 6 bar or 9 bar. Conversely changing flow rate does impact in cup TDS as it's flow which removes solids from the coffee puck. Bottom line: flow rate is more impactful. Changing pressure changes both brew pressure and flow rate while changing flow rate keeps the pressure about the same with only flow rate changing. Marc

Can anybody point me to some source explaining the difference between manipulation of flow and manipulation of pressure? For instance, in this particular case, if one had used a manual lever machine (with pressure gauge) and had chosen to begin the extraction at very low pressure, in what dimensions of flavour should we expect the result to be different to an extraction with low initial flow? What I mean is that I can "picture" in my mind the effect of grinding, the effect of tampering, the effect of pressure (the higher the pressure the "deeper" the extraction of substances from inside the cells) but I cannot figure in my mind the difference, in taste, between pressure effect and flow effect. A slow flow should simply extract slowly, a fast flow, if too fast, should simply dilute the coffee with water. It's pressure which breaks the cell membranes and extract substances, not "flow".

@Wholelattelovepage4 жыл бұрын
Hi neville, I've been asked about the article many times. I need to have a go at comparing but honestly I'm rather skeptical. Here's the comment I've given numerous times with my thoughts... Better Shots? What I read is the beverage was more consistent in flavor shot to shot. Easier to get the same flavor, but was that flavor good? I've had plenty of shots with grind too coarse and lower coffee dose and they are weak, sour, lacking body - under-extracted. From the Science Daily article: "Though there are clear strategies to reduce waste and improve reproducibility, there is no obvious optimal espresso point," says Hendon. "There is a tremendous dependency on the preferences of the person producing the coffee; we are elucidating the variables that they need to consider if they want to better navigate the parameter space of brewing espresso." The article had some focus on "sustainability benefits". IDK... I like a good 12oz steak. If I and everyone else starts eating 8oz steaks that's more sustainable too. Just don't know if I'm going to be satisfied and makes no difference if all my 8oz steaks tasted the same. I don't want them to. I like it when I run into a 12oz steak with exceptional flavor based on comparison to some other really good ones. All very good steaks, but one stood out like a god shot! Honestly sounds like they're making short coffee shots and not what most would consider espresso. More consistent flavor? That might be easier with a coarser grind due to lower flow variable affects. And, maybe it's a flavor that works for some. We have a lot of former (and some current) baristas on staff here. When a new one comes on board I always ask them what percentage of their customers even know there's espresso in the latte they ordered. The answer is usually in the 20-30% range. That number goes up if they came from a specialty cafe or micro-roaster. IDK maybe weaker, consistent "espresso" works for the Starbucks crowd? Not for me. If anything I'm going the opposite direction more coffee and sticking with the finer grind. I've been on a triple shot kick for a few weeks and loving the deep, rich, straight shots with lots of body! Marc

@Wholelattelovepage2 жыл бұрын
Hi Tristan, Thanks a whole latte for the love and your patronage! Your problem is the pre-ground. There's no specific grind size that works universally for espresso. Grind size must be dialed in to match your own espresso extraction variables. Very small changes in grind size can make a huge difference in extraction timing. A grind size which works well in one machine will almost always need adjustment if it's used on another. Grind size is not set and forget. As variables change like the coffee you are using, coffee's age from roast, coffee dose weight in your portafilter, brew temp, etc your grind size will need adjustment. For that reason very few people (like near zero) using prosumer level machines like yours use pre-ground coffee. Grinding fresh right before brewing will exponentially increase youir espresso quality. Here's a video on how to dial in grind size: kzbin.info/www/bejne/oIC8aHdmZ9Nnedk What need is a quality espresso oriented flat burr grinder. One that can grind directly into your portafilter. The Mignon Facile is a bare bones lower cost grinder which has those qualities: www.wholelattelove.com/products/eureka-mignon-facile-espresso-grinder So what can you do with the pre-ground you have? Increasing the dose weight in your portafilter will slow down the extraction if you can fit more. Tamping harder might help a little too. Also be sure your flow control is set properly. Turn it 1.25 turns open from the closed no flow position. That gets you the stock flow rate of the machine without flow control and that's where you want to be when first dialing in or working with a new coffee. If you're already set there I don't think increasing the dose weight or tamping pressure will be enough to correct for shots coming 3x too fast. I hope that helps! Marc

Also my flow control kit is about 1/4 turn off from your tutorial and in another reaction to this video's 1 1/4 turn for normal flow rate.

Hi g, Thanks for the questions. Machine gauge read 8.5 and group was 7.5 - likely because the grind was a bit coarse. But, not concerned at all with the brew pressure. There can be some variation in flow rates based on valve position. Also minor errors in calculation. For flow rate at valve position: One thing to check is if you get no flow when the valve is closed. Not unusual for the sleeve on the shaft of the flow control to drop down a little when the valve is open. Then when you go to close the sleeve prevents the valve from closing all the way. Marc

@Wholelattelovepage2 жыл бұрын
Hi Ben, Thanks for the questions. When doing flow control pressures can go lower - often much lower than the standard extraction 9 bar. You do not need to always be at 9 bar and it's very common to not be. In reality I often pay little attention to pressure when running flow profiles. There's some good research which shows very little difference in extraction yields from espresso pulled in a range of 6-9 bar. Yes, setup your machine and make some espresso aty normal flow rates. On ECM/Profitec machines normal flow rates are obtained with the valve open 1.25 turns. From there do experiment with flow and taste to see how various rates change the flavor. Here's a link with more info about stock flow rates and graphs of 5 flow profiles for use in differenr coffee situations: www.wholelattelove.com/blogs/articles/intro-to-calculating-flow-rate-on-e61-group-machines The profiles in the article were developed by me.

Sorry to be so in the weeds nerdy. Just trying to understand.

Hi CM, You can adjust brew pressure with the flow control installed - works like a blind basket. Just close it and lift the lever. Then adjust to 10 bar on the machine gauge for vibration pump machines and 9 bar for rotary pump machines. You can do prior to FCD install using a blind basket and set to pressures stated above. Hope that helps! Marc

I think I gonna build mine back. I really think it's just not worth it for me at least. I mean I have a nice preinfusion by default from my Mara X and I only drink dark roast, no fancy "single origin 100% arabica washed Ethiopian" . It's just not for me. It's expensive, it's a little struggle to get into, you could break something easily if not mindful while installing. So with that being said.... Does anybody want to buy a Flow profile Kit with a paddle for a Mara X ? 😂

i would love to hear your thoughts/experience on profiling (and any specific starting points) for milk-based drinks, which are typically my go-to. while there is great joy in experimenting with the paddle for straight-up shots, i have experienced an issue whereby a standard 1:2 brew ratio (which worked wonderfully on my older/way cheaper Breville, same beans and same dose) no longer "cuts" through the milk, resulting in a weak milky drink. a ~1:1 ristretto with paddle full open gave me much better results, but i feel like i have yet to maximise the potential of the beans. what are your thoughts on flow profiling/recipes for milk drinks? cheers.
@Wholelattelovepage4 жыл бұрын
Hi Shing, Thanks for an interesting question. I have not done profiling in an attempt to get more coffee flavor through the milk. I honestly am not a big milk-based drink drinker unless it's a cortado, flat white or random wet cappuccino. I dislike gulping straight milk. I want the espresso to be featured so my milk drinks tend to be a 1:2 or lower espresso to milk ratio. If using flow control on espresso for those I'd do what I think is best for the espresso without much thought to the milk. So taming brightness in very fresh from roast coffee with long low flow pre-infusion to first drip at ~15 seconds then increase to a medium flow rate. Or hitting bean blends or older coffee with high flow to start then a linear ramping off of flow/pressure to avoid bitter or stale flavors. I will say that with some coffees like bolder Italian style blends I'm okay with them go long as the bitterness gets tamed a bit by the milk and helps the espresso cut through. Marc

If so, wouldn't it be better to measure the pressure/flow by the pressure gage, i.e. 1/4 turn for 15 seconds and then a 1/2 turn and 6 bar until desired yield is reached? Great video by the way, you guys are the best. No flow control for the ECM Technika V Profi PID?

Hi Jesse, Yes, flow rates at valve positions represent maximum potential flow rates. One can chase pressures if desired. I prefer considering only the flow rate. The pressure gauge provides some information like showing pressure drop at a constant flow rate as the puck gives up solids. That information could drive flow rate adjustment during an extraction.

While the flow rate is fine, the espresso seems thinner. On this video, the gauge didn't show 9 bar either when you ran it open. Is there something I need to do to restore the pressure at the head?

Hi scott, thanks for for an excellent question and your patronage! Your timing is perfect. I'm currently working on a video covering the basics of brew pressure. I'm using an ECM Classika machine with flow control in the video. What you are seeing is normal - and look for my video on brew pressure basics to post tomorrow 3/5. During an extraction you are seeing "dynamic" brew pressure indicated on the gauges. During brewing the group mounted gauge will almost always read lower than the gauge on the machine face. It's measuring pressure in the group so much closer to where pressure is releasing from the filter basket. The machine gauge measures pressure much further up the brewing system hydraulics. What you'll see in my brew pressure video is a drop of .8 to 1.2 bar between machine gauge and group gauge depending on grind size. ~1 bar drop is normal for a dialed in extraction. Thinner espresso may be due to other variables like grind size etc. 8 bar at the group is perfectly fine and normal. One thing I should mention... You may want to close the flow control a bit and not run wide open. At wide open potential flow rate is a few grams per second higher than on a machine with standard mushroom valve. Hope that helps!

Hi Marc, awesome video, I am thinking of getting the flow control device for my Profitec 700. Would you say the pre-infusion without the flow control device is kind of useless in the Profitec 700? I have tried doing pre-infusion but it is not turning out great for me, as soon as I see the first drops, I put the lever up but the shot comes really fast and makes a mess.
@Wholelattelovepage4 жыл бұрын
Hi Mario, Thanks for the comment and question. Flow control opens up a new world of possibilities for sure. I do not believe pre-infusion is useless without the flow control. It's just not as controllable. On a plumbed in Pro 700 one can do a long low flow/pressure pre-infusion and tune the pre-infusion with a pressure regulator on the plumbed in connection. That will definitely help take the brightness bite out of very fresh from roast single origin coffee. If your shot is coming too fast after a pre-infusion that's typically an indication grind needs to be finer. Might try dialing in your grind with no pre-infusion and then use that grind size when you do pre-infusion. But, there is no doubt controlling the flow rate gives one more possibilities. Marc

Hi Jonathan, Congrats on your new machine! Which ECM did you get? You must watch one of my more recent videos on flow control. You can have too much flow! Never run with the flow control wide open. Stock flow rate without flow control is ~11g/s on rotary pump machines and ~8g/s on vibration pump machines. Open your flow control all the way and you'll get close to 30g/s on a rotary machine. Here's a live stream (it's long) I did a couple of weeks ago on flow control. It goes through the calibration procedure so you know how to set for a stock flow rate then goes into some ways to use flow: kzbin.info/www/bejne/eJzagWaAjteeY6M. Starting this Thursday, April 30 I'll be doing a series of live streams over a couple of weeks featuring different flow profiles. This week's is a profile for working with very fresh from roast high-altitude specialty coffee. Marc

Could he be chasing a certain preasure instead of focusing on flow rate?
@Wholelattelovepage3 жыл бұрын
Hi s, Thanks for the question. Sure sounds like someone is chasing pressures. While that can be done IMO it's not the best way to approach using flow control. In most cases I give very little regard to pressure reading. Depends on what type of profile you are using but in my experience and in research there's little difference in extraction quality in brew pressures ranging from ~6-10 bar. That's a simplification to some extent which does not consider edge use cases. IMO and that of the coffee pros I work with around the world flow rate which determines brew water contact time with coffee is far more important than brew pressure and a much easier variable to work with. Marc

@@Wholelattelovepage Hi! A follow up question here. When profiling by using flow rate is that in a way relative to your machines flow rate? What I mean is the machines you have with rotary pump have a flow rate of about 11 ml/s, the ones with vibration pump about 8 ml/s, there are also machines with about 5,5 ml/s, still I guess all machines have about the same flow rate through the coffee when having 9 bar. Will this mean that when profiling your espresso the flow rate will be relative what machine you are using. 50% in one machine is totally different from another. Hope you understand what I mean! :)

Hi, I fitted flow control to my ECM Sync with the new spring included but find the flow builds very fast from Off to 4g/sec in 1/8 turn, beyond 1/8th almost unusable flow its so high. Should I be adjusting the pump? Pump shows 9 bar, 9.5 in group with blind filter. Any advice Thanks Graham
@Wholelattelovepage3 жыл бұрын
Hey Graham, No need to adjust your pump. 9 - 9.5 bar with blind is perfect. Sounds like you may need to adjust position of the sleeve on top of the flow control to allow the valve to fully close. Can check if this is problem by running pump with no PF in place. If you fully close the valve do you still get flow from the group? If so, then that's the problem. Sleeve is held in position by turning the control knob. If that sleeve is loose on the valve stem it can drop down and prevent valve from fully closing. To fix loosen the control knob so the sleeve over the valve stem can move up and down on the stem. Then fully close the valve so there's no flow from the group with pump on. Then raise the sleeve on the valve stem a bit so it's not bottomed out when valve is fully closed. You can put a thick card under the sleeve temporarily to hold it's position up a bit while tightening the control knob to hold the valve sleeve in position. Hope that makes sense and solves your high flow rate! Marc

Hey guys I am going to create a coffee bar in the near future. Right now I have a Breville barista express. This machine has served me well making on average 4 milk based drinks a day for 3 years. I currently have my water running through a softener then and RO system. As I fill the tank with RO water I add drips of minerals back in. I have a couple questions? 1. If I plumb in water line will the inline filters that use ion exchange still work if the water has been through and RO system. Not sure if those filters rely on calcium being present in the water to complete the exchange of minerals 2. I have narrowed it down to Prof Pro 700 and Bez duo. I like the volumetric on the Bez, but really like the organization of internals on Prof. What is the difference in group heads when it come to maintenance and temp stability. Also which machine in your opinion will is better in terms of reliability and taste in th cup? Thank you
@Wholelattelovepage4 жыл бұрын
Hi M, Thanks for the questions. 1. If referring to a BWT Bestmax Premium inline ion-exchange filter I would not connect that directly to the output of an RO system. You can use an inline BWT BestMin cartridge to remineralize RO water: www.wholelattelove.com/products/bwt-bestmin-premium-m-filter-cartridge Perhaps your situation is similar to the one in this customer comment on the Bestmin page linked above: "Well water with 25 grain hardness is softened leaving 450 ppm NaCl which is removed by RO. RO water is treated through this unit yielding TDS of about 90 making great coffee with an ECM double boiler machine. Highly recommended." 2. The Pro 700 and Bezzara Duo DE are both nice machines. The Duo uses Bezzera's BZ group which is electrically heated and temp controlled using PID. The Pro 700 uses an E61 group with thermosiphon for heating. The electric heating of the BZ group helps to warm up the machine faster. Both provide accurate brew temps and if warmup time is concern you can power the Pro 700 through properly sized smart plug for automatic turn on so it's ready to go when you are. The Pro 700 is a lot less complex internally than the Duo. Long term it's the more reliable machine IMHO. For about the same price as the Duo you can get a Pro 700 with Flow Control on the E61 group which opens up a world of possibilities. Here's a link to a side by side spec comparison with current pricing for both machines: www.wholelattelove.com/pages/compare?products=MTU0NjAwNDEzNTk5NSwyMDM4MTQ2NzI3OTkw Hope that helps! Marc

Hi, I like this video and the setup a lot, especially the before/after and the approach with scales etc. However there are two things that I don't understand, maybe you can help me out here: 1) in the first shot, to me it looks like you have really massive channeling, right at the start of the shot, which is .. well, very bad. I would assume that the extraction is pretty uneven, and that you would taste this. You mention channeling briefly, but like as an aside. If this were in the last third of the shot, I would be less concerned. But here, you almost have spurts to the side. That's really bad. And I would assume that this is either due to bad prep (grind distribution / tamping etc), or not the grind is already too fine. Are you sure this is not due to "leveling only", and lack of tamping? 2) you do a slow, long pre-infusion, then you go up to 6 bars of pressure. I would be curious to know why you did not go higher than that (classic 8-9 bars) - is there a reason? Don't get me wrong - I like the setup and I think the video is great!
@Wholelattelovepage3 жыл бұрын
Hi j, Thanks for the comment and questions. It's been a long time since I did the video so not certain on #1. It's entirely possible there was channeling. With proper leveling I get more consistent shots than with tamping alone. IMO hard tamping is over rated. You can only compress coffee so much. Also I tend to grind finer. On #2... Long slow pre-infusions and lower flow rate extractions are a common way of taming the brightness in fresh from roast specialty coffees. I'm not very concerned with the brew pressure. It's more about the flow rate of water through the coffee. Flow and pressure are related but not one in the same. There's some good research showing little difference in extraction of solids in brew pressures ranging from 6-9bar. Marc
