Metric · Decaf Huila Pink Bourbon

Grind 29 at 18g dose, 38.1g yield, 29 seconds — clean numbers right in the target zone. Balance logged at 2 (sour), but your notes say the sourness dissipates quickly after mixing, which is the bright EA Washed character you've seen before on this bean, not an extraction fault. Solid shot on paper, though the fast dripping near the end warrants attention.

Time (29s) and ratio (2.12) are both Normal — nothing to chase here technically. The balance 2 with quick-fading sourness after mixing is consistent with the pattern you've already identified on this bean: it reads sour on the surface but opens up when stirred. The fast bilateral dripping around 25 seconds is worth noting — this is likely the natural puck breakdown toward the end of extraction rather than mid-shot channeling, since flow was even at the start and both spouts dripped simultaneously rather than one lagging behind. No red flags in the numbers.

EA Washed Pink Bourbon at 12 days post-roast sits right at the edge of the estimated peak window for this process type. That's actually ideal — the bean has had just enough time to degas without losing the brightness that defines it. The Luxardo and orange peel notes are consistent with that quick-fade citric sourness you're tasting. This bean is inherently forward and bright; balance 2–3 with clean finish is likely its ceiling, not a sign you need to go finer.

Two consecutive even-flow shots at grind 29 with no left-spout lag — the channeling issue from grind 28 and 28.5 is definitively behind you. Grind 29 is confirmed.
