Knluk Just curious, isn’t this a bit on the longer side for dark roast?
Considering that the typical Italian recipe is 7 grams of coffee for 25 ml of liquid (say 22 grams, as there is crema?)… no, I wouldn’t say it’s long. A 1:1.something I would call a ristretto.
Then again, I don’t really buy the hokum-pokum of “3.735 seconds at 2.439 bars of pre-infusion followed by an extraction phase of 27.189 seconds - not a millisecond longer - resulting in a 1:2.154 ratio” etc. etc. - I know what I like in the cup, and I will adjust my technique to get it. 18 grams in, 45 out seems to work for me; you do you. 😊
FWIW, I’m finding it interesting that the INEI (Istituto Nazionale Espresso Italiano - National Institute for Italian Espresso - which is an association of manufacturers and has no official status, despite the resounding name) states a 25 ml ‘standard’ on their Italian page http://www.inei.coffee/it/Cose.html - but there is no similar text on the English page… (although they do mention the 25 ml on the “Cappuccino” page, so that’s another conspiracy theory busted).
The “7 grams of coffee in 25 ml” kind-of-standard (sorry - all in Italian):
Note - I’m not saying that “7 grams (for a single) in 25 ml is a rule and anything else is wrong” (heck, I’m using 9 in 30 or thereabouts!), or that the websites above are particularly authoritative. I’m just saying that it is a fairly accepted custom/standard in Italy, and - outside of competitions, where I have no idea what they do - it’s what baristas and café owners budget with.
Knluk Maybe train up your girl?
It’s nothing to do with training; it’s to do with liking. She is fine with one coffee - or fewer - a day; the other three in the family want more.
