Notes

Flow started front to back and merged into a single stream at the front. Some spraying throughout. Taste is balanced and rich, but the dark roast is still a detractor for the score

Really good drink without sharp notes. A bit of the dark roast noticeable. Taste like chocolate. Latte art was good with a well formed simple hart and milk frothing was wxcellent

Summary

Shot 6 on the Uncommon Brazil Cerrado, back at grind 42.5 after last session's coarse miss. Nailed the ristretto target — 23s, 28.3g yield, balance 4, quality 4. Some spraying noted on the naked PF throughout, but taste landed balanced and rich. Dark roast profile remains a personal detractor for Diego, which is a palate fit issue, not an extraction one.

What the Numbers Say

Time is Fast at 23s, within your ristretto target window of 20–25s. Ratio is Short at 1.55 — hit your 27.3g target within 1g. Balance 4 is exactly where you want it. The spraying on the naked PF is worth noting: it suggests minor distribution inconsistency, but since taste is balanced with no linger, it didn't produce a meaningful channel — just some turbulence early in the shot.

The One Thing to Change

Lock grind 42.5, dose 18.2g, target 26–30g yield. The spraying is worth monitoring — if it worsens or balance dips sour, bias the final 10s of WDT to the front/right quadrant.

Shot is dialed in. Taste is balanced, target hit, and the coarse regression at 43 is confirmed fixed. The spraying is mild enough that no change is warranted unless it correlates with a taste shift.

Bean Context

Dark chocolate, walnut, and dried fig profile is consistent with what you're tasting — ashy and burnt chocolate impressions are characteristic of dark natural Cerrado at this roast level, not extraction issues. At 14 days post-roast this bag is squarely in peak window for a dark natural. The profile just may not be your style, which is valid — but the extraction is clean.

Progress

Recovery from the grind 43 regression was immediate — one shot back at 42.5 and you're balanced again. The coarser limit on this bean is now clearly established.
