Notes

Flow started edges to center and started to flow at 12 seconds. Taste is slightly bitter but not lingering. I am not sure if I am a fan of the bean profile but will taste more.

Summary

Shot 2 on this Uncommon Brazil Cerrado — you jumped from the failed grind 35.5 (choked immediately) all the way to 41.5, and the machine ran. 28 seconds, 25.8g yield, slightly bitter with no linger. The first shot was a failure, so this is your real baseline. You missed your ristretto target by 1.2g short on yield and ran longer than the 20–25s target window, but the extraction itself is readable.

What the Numbers Say

Time is Normal at 28s. Ratio is Ristretto at 1.43 — you came in just under your 27g target. Balance 5 (slightly bitter) with no linger is a decent sign for a dark natural: the bitterness isn't compounding, it's just the roast character showing. Flow from edges-to-center with a late start at 12 seconds is healthy naked PF behavior — no channeling flag here. Lag was 5g this shot, consistent with this equipment and bean.

The One Thing to Change

Go 1 click coarser to grind 42.5 and target stopping the pump at 20g to hit 27g yield.

Slightly bitter with no linger on a dark natural at 28s says you're in the right zone but just a touch over-extracted. One small coarser move should open the balance toward center without blowing out the yield. Your lag is 5g here, so stopping at 20g should land you right at the 25g mark — bump the target to 20g stop and see if you can get closer to 27g in the cup.

Bean Context

Dark natural from Cerrado at 10 days post-roast — you're right in the peak window for a dark roast, so freshness isn't a factor. Dark chocolate, walnut, dried fig profile is consistent with the slightly bitter, full-bodied read you got. Mellow acidity is also confirmed — no brightness to wrestle with here. This is a forgiving bean profile-wise; the question is whether the flavor actually appeals to you. Your note 'not sure I'm a fan' is worth taking seriously — dial it in one more shot before deciding.

Progress

Big grind jump (35.5 → 41.5) to escape a choke was the right instinct and landed you in a workable range on shot 2. That's solid recovery decision-making.
