This is excellent, I’ve only been getting about 18seconds for the extraction but this was from when the droplets appeared as I was “told” I was supposed to wait to time it. This now means I’m probs closer to 27/28seconds for the whole thing for 38g from 18g in which sounds pretty close. Thanks!

Been watching that transition from mouse-tail to 'wobble' for many years without thinking too much what that meant. Appreciated learning the explanation of that, plus a few other fine points (such as new vs old coffee expansion). All laid out clearly and logically, and very easy to follow. Very useful information that will likely help transition to a new coffee more quickly. Also I've not used the prebrew function of my late model GS3-AV as much as I should have, but will try your 2s 'on' +2s 'off' + 'finish' a try now that I know what to look for (I might have been overdoing it).

Great video, but left me with a couple questions. First, should you have stopped at 1:1 (at 5:25), can you call that a ristretto? Second, is the "wobble" as easily noticeable with bottomless portafilter? TIA for this and all the knowledge I've gotten watching your channel.

[@ArtistiCoffeeRoasters]

A 1:1 is a ristretto, you can stop there if that’s what you want to achieve, seeing the wobble is the bottomless is a bit harder, it will be a faster pour and very pale.

[@ArtistiCoffeeRoasters]

No as it’s a vortex, look for the blonding and weigh your shot for your recipe end weight

[@coyzmann]

Great video Question though : If we already dialled in with ratio 1: 2 in 30 secs, If we want lesser ratio, say 1 : 1,5 (ristretto) do we reduced time to around 20 - 23 seconds, or do we grind finer to reach 30 sec for that ratio?

[@ArtistiCoffeeRoasters]

Keep the same Recipe, don’t change the grind, stop the time at the ratio you desire. 👍🏻

[@oracla]

Actually a ristretto requires a finer grind. However that would be a nightmare for a cafe, so the don't do it like that.

[@nimitzg]

@@ArtistiCoffeeRoasters sounds off to me. if you need a lower yield and would like to keep that great taste of recipe you need to re-dial in your shot: lower your dose in,keep ratio,change grind (resistance has changed) wish for the best and taste.re-adjust again by taste. If you just stop the shot earlier you'll get it sawer/salty.

[@anthonybotonis5841]

Artisti coffee knows whats going on. A ristretto means (restricted) as in restricted espresso. The last part of an espresso extraction gives a watery bitter taste which balances out the espresso taste. A ristretto is a punchy sweet shot with a heap of body which is what a espresso is 2/3 of its extraction so thats where you stop the shot about 22sec in from a 30 sec 1 to 2 ratio espresso

[@lloix]

As always, a thorough discussion of a topic we've all wondered about. I'm going to be watching out for that wobble! One question: any tips for those mere mortals among us who have to rely on a semi-auto without a pre-infusion option for their daily brews?

[@ArtistiCoffeeRoasters]

It’s not a shame to have a semi auto, it’s better than instant! 😂 find fresher roasts and allow the beans to expand as they usually can’t grind fine enough so use the puck expansion to your benefit

[@lloix]

@@ArtistiCoffeeRoasters Yay! I'm regularly getting my roasts within a day or two of the roast date (although I age them exactly as long as each roaster recommends), and I have a Ceado--that must be why my pedestrian palate has been so happy with my home brew!

[@ksquire1]

Would it still work to aim for 30-32 seconds, but for a much smaller dose like 15g in, 30g out?

[@ArtistiCoffeeRoasters]

Yes, you may fine it’s more like 28-30 but if it’s not and acidic coffee you can push the pre infusion a little longer to say 10 sec and get super syrup drips at the start

[@robbob1492]

@@ArtistiCoffeeRoasters Not sure if I understand. For a 15g basket, 30 grams out, in how much time? From when you start the group head or when water hits the cup?

[@ProperCh]

@@robbob1492 the exact time doesnt matter to be honest. Its just a measure to see how long the water contacts the coffee for propery extraction. If its too fast the extraction will most likely be underextracted if its too slow its most likely to be overextracted. Its more important to watch how ur shot flows and how it taste in the end than shooting for an exact extraction time. Thats why the recommended range for time is 20-30 or 25-35seconds. You can measure from first drip in cup or first button press. When comparing times it will be the same if ur consistent with how you time.

[@ArtistiCoffeeRoasters]

The 18g etc is the lower smaller baskets. We like the larger dose to help with the larger milk volumes.

[@fabricedevos4273]

Thanks for this very instructive video. I think I have understood why sometime, after having brew a coffee, the puck is stucked to the grouphead (so when I remove the porta filter, surprise! it is empty...). Probably because there is a too small amount of coffee and the grind size is too small and need to be ground coarser.

[@mannyk7634]

too small amount of coffee usually results in the opposite problem - of the puck breaking up or have dents and holes on the top. Sticking to the group head usually means too much coffee or too shallow tamp

For example, if I'm aiming for 20gr in to 40gr out in say 30 sec. Am I counting pre-infusion as a part of that 30 secs? Or do you ever say your pre-infusion time then do your 30 secs of regular extraction? Thanks! Troy from Kansas City, Missouri USA!!!!

It’s counted in the 30 sec, so you can assess the how the coffee is reacting

[@KatinkaEnglish]

How much water do you have programmed to come out of the machine in order to get your 45ml espresso at the end?

It is not about programming the water amount, it more about getting the extraction perfect then you set the volume based on the espresso you get not the amount of water that goes into the espresso

The yield should still be 1-2, time is flexible so try a longer and a shorter time and then taste, some coffees do change recipes, these are a standard to work from and use taste to adjust. If over extracted taste lessens the time

[@emmanoble5498]

What is a general rule of thumb when it comes to pre infusion times? Between 5 -10 seconds? From spout to cup? Does running the shot down the side of the cup as opposed to in the centre make any difference to the crema? And the pour,is 30 secs roughly optimal ? What does the perfect start of the pour look like? , (optimal drip to mouse tail ratio?) What is too old for bean age? How Does room temperature changes from colder in the morning to hotter/humid later in the day affect the variation of extraction?( I know it does affect the grind) does it affect dialing in the weight of your shots? with a sometimes 20 degree temp to 80 % humidity shift ? How do you nail the extraction of pre ground decaf, Without losing your dignity and the will to live ? Lol

Nova simonelli Apia versions came up with a "Soft infusion" system which throws out these classic look outs out the window. Now usually a gush of liquid comes out as soon as you press, then slows down (even to drops) later. I personally don't like Nova simonelli's approach. How ever I have to admit, the soft infusion, does reduce channeling significantly, that we used to get in VBM.

[@StefanHanrath]

Try to get a very freshly roasted bag of beans (ideally roasted a week earlier). If impossible to get a fresh roast, perhaps illy will work in a pinch (their cans are well sealed), and try with a darker roast (with darker roasts, to counter bitterness you may need to adjust grams of ground coffee : water ratio, to less water output, e.g. less than 1:2, more towards 1:1,5) Low temperature may also lead to underextraction (sour / salt) if your machine & filter holder aren't heated up properly.

[@ArtistiCoffeeRoasters]

What a great reply, thanks Stefan. The coffee your using will play a big part in this. Try find a coffee the is aged between 10-20 days. If coffee is too fresh (under 7 days) it will be more acidic and can be sour. I can only assume your trying this black? If you're drinking it with milk, I'd be questioning the milk too. Sourness is usually representative of under extracted coffee. Going finer isn't always the answer, especially if you've got not a large dose. I'd be trying to increase your dose rather than reduce it. Hopefully this helps, let us know how you go.

[@JuanPablo-kj9dg]

@@ArtistiCoffeeRoasters I'm using the Illy and it's fine, the other one at the same settings is still acid, I'll try to reduce the dosage and see what happens.

[@riaanventer1816]

Does it depend on the type of the coffee or how much you put?

[@ArtistiCoffeeRoasters]

its is more about the amount of coffee, as the varying grind amounts slow down or increase the flow giving you more or less time

[@jackmesiha960]

Thx alot

[@nguoffroosvelt9133]

Good time

[@ArtistiCoffeeRoasters]

👍🏻

[@Bernard-p5y]

Please note the timer should start when liquid espresso enters the empty cup which has already been tared and is at 0 grams. How can you properly time a shot since different machines may or may not have pre-infusion with a delay following infusion. Also different machines may have different start times due to the type of pump or inherent differences in the machine. I will re-iterate. The timer should start immediately when it detects a change in weight of the auto-tared vessel and end timing when weight change terminates. This is how I time a shot even when using different machines. Weight of coffee grinds in to weight of liquid out determines the ratio while keeping extraction time to 20-35 seconds. Above or below these times adjust grind levels

[@oracla]

I would argue the explanation about the puck "floating" is incorrect. What happens with finer grind is you wash out more of soluble material and the puck actually shrinks and reduces its pressure to the walls of the basket (also, the soluble material is inherently sticky and with a good extraction there is less "glue" in the puck left). This is not a problem as the puck only "floats" when the solenoid valve kicks in and there is a moment of reduced pressure in the group head which pulls/lifts the puck.

[@MarFor0]

+1

[@ArtistiCoffeeRoasters]

Hmm.. thanks for the info, what you are talking about I will assume your have watch the clear naked handles videos on extractions. Yes the exhaustion of pressure from a solenoid valve or a manual leaver closing will such the coffee puck up or show up cracks in a puck. But it will not effect the flow of the coffee (while water is still flowing) which Is presented as a very fast flow at the end or about 2/3 through the extraction.

[@oracla]

Ok so I guess we agree. The puck is not at any point floating during extraction but after the fact. The reason for the fast flow is simply because the puck erodes. FIlter baskets are usually slightly curved at the bottom and we usually use flat tampers, so the puck is a bit thinner on the outside, that is where extraction (given the technique was generally good) and also over extraction (fast flow) begin. This can be seen on a naked handle.

[@SanMartan]

I stopped worrying about time along time ago...more what I can get out of each coffee using different pressures throughout the extraction
