Notes

Flow started at around 9 seconds from edges to center forming a clean single stream. Shot was slightly slow today generating slightly bitter tones. Taste is mostly balanced though and although dark roasts are not resonating with me is other roasts, this was a good shot

Taste is good with notes reminding me of rich chocolate. Slight bitter aftertaste. Milk steaming was a fail today so just big bubble foam on top without art

Good Shot

Summary

Shot 4 on the Uncommon Brazil Cerrado — grind 42.5, 18.3g dose, 27.6g yield, 27 seconds. Clean naked PF flow, borders-to-center merge, balance 5 (slightly bitter), quality 4. Your notes match the numbers: the extra 4 seconds vs. your last pull pushed it slightly bitter, which is consistent with a coarser grind hitting the slower end of its range on a given day. Still a solid, well-extracted shot.

What the Numbers Say

Time is Normal at 27s, just inside the good range. Ratio lands Short at 1.51 — right on the ristretto target yield (0.1g over). Target time was 20–25s and came in at 27s, so the yield was nailed but the shot ran a couple seconds long, nudging balance from 4 to 5. Flow was clean on the naked PF, no channeling. Taste (slightly bitter, no linger) matches what a 27s pull at this grind typically produces on a dark natural — not a problem shot, just slightly on the extraction-forward side of the dial.

The One Thing to Change

Hold grind 42.5, dose 18.3g, target 25–30g yield.

The recipe is dialed in. The 27s time is within normal range — the slight bitterness has no linger and is consistent with this bean's dark/ashy profile rather than over-extraction. No adjustment needed.

Bean Context

Dark chocolate, walnut, and ashy/burnt chocolate notes are true to this Cerrado's profile — low acidity, full body, dark natural roast. At 12 days post-roast it's in the peak window. Your notes across shots 3 and 4 are consistent: the profile is solid, but you're noticing the dark roast character isn't resonating with your palate. That's a preference observation, not an extraction problem — the shots are well-pulled.

Progress

Two clean back-to-back shots on the naked PF with balance 4–5 and no channeling. The Cerrado is dialed in; the remaining question is purely whether the dark/ashy profile is a bean you want to keep pulling.
