Notes

Flow started at 8 seconds and remained mostly even throughout the shot outside of a few seconds of fast dropping on the left spout. Taste is bright which resolves quickly with a bit of aftertaste.

Summary

Shot 68 on the new Unicorn Blood bag — grind 40, 17.7g dose, 35.9g yield, 30 seconds, balance 3, 3 stars. Flow was mostly even with a brief fast-drip moment on the left spout, and taste landed bright with quick resolution and a bit of aftertaste. The recipe transferred cleanly from the prior bag.

What the Numbers Say

Time (30s) and ratio (2.03) are both Normal — right in the sweet spot. Balance 3 (slightly sour) with quick-resolving brightness lines up exactly with what you've established as berry character on this bean, not an extraction issue. The brief left-spout speed burst is consistent with minor puck variation, not channeling. 7g lag is normal Bambino behavior.

The One Thing to Change

Lock grind 40, dose 17.7g, target 34–38g yield. Nudge yield toward 38g next pull — you're at 35.9g, so aim for 37–38g to fully open up the cup.

Everything is dialed in. The only remaining nudge is yield — slightly short of the upper target range, and a bit more volume should soften the brightness and reduce the aftertaste without touching grind.

Bean Context

Flavor profile is behaving exactly as expected — dark chocolate, caramel, and berry with bright acidity that resolves fast. At 24 days off roast this bag is in peak window and extracting cleanly. Prior bag dialed in at the same recipe, and this bag is tracking identically on shot 1. No changes needed on the bean front.

Progress

Recipe held across bags on the very first shot — that's a meaningful consistency win. Grind discipline and WDT control are paying off.
