Notes

Flow started edges to center and stayed in four streams for a few seconds before converging into a single stream. Flow was slightly restricted and wobbly leading to a hit of over extraction with slight. Otter tones but the taste was mostly balanced without lingering notes. Good crema. Could have stopped the shot a gram or two later to get more tiekd

Good Shot

Summary

Shot 8 on the Brazil Cerrado, pulled as a ristretto. Time and target both hit — 23s in range, yield landed at 25.5g which came in 2g short of your 27.5g target but you nailed the ristretto call. Balance 4, quality 4, clean finish with no linger. Your notes flag slight over-extraction tones but the overall taste was balanced — that's a well-pulled shot.

What the Numbers Say

Time is Fast (23s) and ratio lands at Ristretto (1.39). The ristretto target was hit on time and close on yield. Balance 4 and clean finish confirm the numbers — no contradiction. The 7g drip lag is normal for the Bambino.

The One Thing to Change

Lock grind 42.5, dose 18.3g, target 24–28g yield. You noted you could have stopped a gram or two later — next shot aim for 27–28g to recapture that range and push balance toward the sweet spot.

Everything else is working. The slight over-extraction hint in the notes tracks with the yield running 2g short of target — a marginally longer pour should smooth that edge without opening up the sour window you hit at 43 and 28+ grams.

Bean Context

Dark chocolate, walnut, and dried fig notes are showing up in the cup — the ashy burnt-chocolate character you've noted across this bag is the bean's roast profile talking, not an extraction flaw. At 16 days post-roast this is squarely in peak window for a dark natural. The slight over-extraction edge at 25.5g is consistent with the pull being a touch short — this bean rewards being stopped closer to 27–28g on ristretto.

Progress

Three of your last four ristretto pulls on this bag have landed at balance 4 with clean finishes — the dialing-in work here is done. The one outlier (shot at 43 grind, sour linger) confirmed the coarse ceiling. You're in maintenance mode.
