Oracle Touch - Time to first drop relevance?
the touch runs you through a tutorial at the beginning, telling you to set the grinder to 30 and just look at how long it takes for the first drop to come out of the portafilter.
(if it's below 8-12s, it asks you to grind finer)
I played around a fair bit, set the inner burr to 4 (from 6) and my last bag of beans had me at 20-21 grind setting to get within those 8-10s and to a nice 1:2.5 - 1:3 ratio within 25s (default time) with the single filter basket..
the coffee was good, Espresso not so much..
I just switched beans and got like 1:6 in 25s..
eventually, I was at 5 on the grinder to get 8s before the first drop, but then it took 40+ s to get 1:2 ratio 🤣
when I went up to 10 on the grinder (always cleaning and flushing the grouphead, and "purging" some powder with the grinder after adjusting) I got a nice 1:2 ratio, but the first drops after 4 or 5 seconds . (it is NOT too watery, though..)
so,
TLDR:
Does anyone care about these 8-12s to first drop or do you simply use a balance and dial in for 30-35s total time?
(I honestly don't understand this extraction time yet.. the Touch doesn't pre-infuse or anything.. it just begins pumping.)
