This was the single best tutorial I’ve seen so far! After much trial & error, mostly error, this finally got me the extraction I’d been aiming for! Loved the coin trick! Thank you for posting! 😃👍👍👍

[@flipthebuzzard]

I second this!!

[@joncooke2450]

I also third this! A great video, thanks

[@markjosephbacho5652]

I didn't get the part after he got the 18.5 grams. That part where he was making coffee onwards.

[@linemartel6244]

Best tutorial! I was struggling tuning my Rocket Fausto touch, and went through so much coffee without getting there. This tutorial got me where I needed in no time. Thanks!!!

[@peaceful3250]

Dialing in has been the bane of my existence. This is the clearest instruction on this topic that I've seen. Thank you. Now I won't go to the clothesline and hang myself. 😉

[@maciejz3665]

By far best coffee grinding tutorial on youtube. Made me feel miserable with my skills, and from now I had to add 0.5h extra from the time I'll wake up to the time I leave the home.

[@yttean98]

what's he is doing is coffee calibration to Optimal taste, After you calibrate, you can make your coffee for that coffee type the same everything you make coffee then it is suboptimal. That's OK, even the coffee shop's coffee is suboptimal in the majority of their shots.

[@taroman7100]

Now I'll be obsessing.

[@brandoncrampton7511]

Im confused so you put in the coin and then ground finer so you would have more space, but then increased grind size with the same weight later to get the extraction to be quicker. So didnt that just remove the head space you wanted originally?

[@samuelseager6785]

Exactly my question. He adjusted the grind size to make head room, now he is adjusting the size to change extraction time. Which one is correct. This didn't make any sense.

[@marksutton5834]

This video set me straight. I didn't realise how important the head space is but I couldn't achieve the coin setup.

[@yttean98]

Very helpful and practical. Thks.

[@MrJobcon]

Very informative. Thank you

[@SIDHATHSAGAR]

Thanks man, You explained so well. On Point.

[@johnmcguiness7096]

Great advice I just went through the procedure with my E61 Rocket and ECM S-Automatik, I am now using less coffee but finer grind, with my single shot basket and 16gm before and 32 g after, thanks for the simple to follow advice

[@KzFilya]

Hello. I have a question. How we adjust the single basket after we found the perfect proportions? I suppose we don't need to mess with the finesse and probably need to adjust it through the time the grinder works?

[@dhonepanganiban9239]

Thank you🤝

[@TomMaynard--TCM--]

5p = 1.7 mm US nickel = 1.95 mm US dime = 1.24 mm

[@domkid6723]

Neat, this comment just made me look into this. Didn't think of it when I grabbed a nickel to try. Turns out a Canadian Nickel is even closer to 5p than an American(Weight and Dims). So if Americans have some Canadian nickels around go with that. I always have some American coins around.. Though I know it's a bit more rare for Americans to have Canadian nickels around... but if you did, It's an almost identical comparison to the 5p. Maybe useless but Thanks internet!

[@mickey08love]

Its kinda crazy that its just coffee but the way it needs to be done is like a science experiment

[@sPacEc0w60y]

Making a good cup of espresso isn't rocket science. After watching this, though I'd say it's pretty close!

[@taroman7100]

Yes, it's all about the science. I'm a dolt still.

[@TheThoover]

Hello, a grind question for you. I purchase and grind my beans at Costco - I ground my last purchase a little to fine. Can I mix some slightly coarser grinds with those fine ground beans ? I'm thinking that would keep the portafilter from packing off.

[@desiastriani8691]

making a coffee is easy. Making a good coffee take knowledge

[@varunshinde6884]

Can you please make videos for manual grinder.. will big help

[@KikixPT]

can i do north south west east? instead of north south east west? it's been working better for me

[@AshisKumar]

Wow..!

[@luangoria2]

mate ahahahhahahha that is definitely a very particular technique, id rather respect the basket size which is written on it and cut the coin part. loved the video. theres no secret for dialing in.... set a starting point, lock the variables, make ajustments and taste for balance between sourness and bitterness

[@taroman7100]

You cheated on your exams---ha.

[@HollaPena]

I want to do this but I can't find a 5 pence piece in California... Can I order one online?

[@megajig]

A KRUVE Sifter would help calibrating the grinder :)

[@taroman7100]

Not all of us can follow through with fresh beans that have enough moisture to clump. With the price and availability of good quality beans growing ever higher we can only work with what we have and that is often beans on the fast track to drying out.

[@cody22cannon]

Has this channel moved or are they no longer posting anything?

[@BWWGL9]

This is more of a Set-up video, shows U, the different "variables" in the basic procedure(s). Not a Taste test, that varies with the Brand & Roast, but the Actual Set-up is the same for all Espresso Coffees. Thanks for very informative video.... :-)) Also, the GRINDER is just as important as the Machine, if not more so. I have excellent Espresso machine, BUT my Grinder cost about 1/3 MORE than the Espresso Machine. If you can't delivery the GRIND, a $3000.00 Machine is going to deliver the Espresso your looking for..... even a $10,00.00 machine! thats my 2 cents. I've been Roasting Beans for 20 years, and drinking well made Coffee for 59 years.... I just started the Espresso thing, why, because it's hard to beat a Excellent Cup of Black Coffee. I'm not much on CANDY DRINKS, they seem to cover up the Coffee.

[@pablo-zn1mg]

BWWGL9 so what’s your preferred brew method ?

[@iplaybose]

west is left, east is right

[@Mrbradstar01]

God this guy likes the word of rule of thumb

you mean 7-11 seconds for pre-infusion, not the time after pre-infusion...Right?

[@GetBennidover]

Do this at home, if I walk into a cafe and the barista is doing north east south west for two hours I'm out

[@yttean98]

This is about coffee CALIBRATION. It's done even before you enter the coffee shop.

[@showingYOUtheworld]

You are funny man 🤣🤣🤣

[@davidkennerly]

Does anyone get the idea that barista practices have the effect of unnecessarily wasting a whole lot of perfectly good coffee grounds?

[@226557547]

In absolute amounts, yes, they probably waste more than home espresso makers. In relative terms? They waste very little because this process isn't repeated except for every few hundred pulls.

[@TheByronian]

Good baristas don't throw away coffee unnecessarily like the video shows. That is an awful distribution technique. You can use "stockfleth", tapping or even a distribution tool. I don't think business owners/baristas are happy with wasting money. They want efficiency, fast workflow and make money while having their clients happy.

[@alansaxon]

I don't see the relationship between the 0.5p test and grind size. Can you explain please. Thx

[@Poraqui]

The first step in grinder calibration, according to this video, is to find out the ideal ammount of coffee for a given coffee filter/basket size. Because the coffee grounds swell during extraction, the basket needs to be filled in a way that allows space for this swelling. What he did was to simply fill the basket starting from a visual baseline grind size (compressing ground coffee with the hand), distribute the coffee (north, south, etc), tamp the grounds and insert the coin. Upon inserting the portafilter in the grouphead if there's an accentuated coin impression, this means that the basket needs to be filled with a finer grind allowing more compression after tamping. If after the grind adjustment and tamping, the coin leaves a faint impression, the right ammount of coffe for that basket was achieved. Remember, there is no TAPING down the portafilter as it is being filled by the working grinder, just a level off and only after that we procede to TAMP down the grounded coffee. The way the basket naturally fills depends on the size of the grind and in this case it has to have a size that after tamped doesnt allow the coin to be hard pressed when the portafilter is placed in the grouphead. The featured basket's optimum ammount of coffee is 18,5 grams. after this, as long as there's always this ammount, the only job left is to fine tune the grind size ( within a certain range, of course) for an extraction according to the baristasa needs.

[@RedBerryCoffeenista]

Sérgio Teixeira The only issue with this method is that once your reset your grind size to reach your ideal extraction (time/tds/extraction%/taste) you will have adjusted your headspace.

[@226557547]

Finer ground coffee compresses more.

[@iamkarandesai]

ok so it might be complete Bs cause if you notice he changed the grind size and made it finer to satisfy the coin test, and the result was the extraction took too long (overextraction) so he basically changed it to a coarser setting to pull his shot in 20-25 seconds.

[@nickmann9445]

The coin test is only to establish how much coffee to use in the basket while allowing head room for expansion of the coffee during extraction. The grind is then adjusted for brew time which is anything between 20-35 seconds dependant on personal taste and preference.

[@Felix-xj3np]

You should first press the button (on the coffee machine) Than place the cups, now there is a chance you burn the coffee.

[@Felix-xj3np]

but good explanation on how to adjust the grinder thanks!

[@suew4609]

@@Felix-xj3np First, then, not first than. Don't worry or get mad, it seems more than 50% of people make this very common mistake. "Than' is for comparison, his shoes are bigger "than" mine.

[@ellisharosli1203]

what if my grinder is set to 1 and it still isn’t fine?

[@CorrupteddSanity]

Have you tried asking it nicely? Otherwise maybe it's time for a grinder with finer settings.

[@dilshypereira157]

Get a new grinder

[@xcvsdxvsx]

Following the instructions on this video leads to the conclusion that I need to go finer, but If I go finer my espresso machine just starts blowing water out the back like I have the blind filter in.

[@Poraqui]

Some machines can't cope with some coffee fineness. If you don't want to change machines, portafilter etc, go for different coffees. And or try to get the coffee freshly roasted (forget that nonsense about having to wait 7-15 days after roast to have a good tasting coffee or some variation on that topic) From my experience, freshly roasted coffee in general doesn't need to be grinded as fine as coffee that it's not fresh. Ex. If I take longer than usual to spend the 1kg that I get freshly roasted, what I observe is that at a given point, usually about a week after purchase, I need to make the coffee finer and sometimes updose in order to have a somewhat enjoyable extraction. Humidity might play a role, but the same happens during summer time and I live in a very mild weather country.

Brew ratio 2:1? An espresso would more be 3 comma something to one...

[@fabduck9275]

nope, a common concept for espresso is 2:1, 2,5:1 is also a good benchmark but 3:1 is kinda long to be espresso, it s a lungo

The truth is while his Tecnology may be correct...most people are not willing to follow the process...nor can they taste results of his efforts...Now this is science...as people get older. They lose two,things...their Hearing and their ability to taste...so,by age 50.....30 to 50 % of both are gone..so,if your 20 years old...enjoy..but if your over 30...Good Luck
