Notes

Flow started edges to center around 10 seconds in. Flow seemed slow but was even and centered across a single stream. Taste is bright but resolving

Great Shot

Summary

Shot 2 on the new Matas bag (bag 30). Clean 32s pull at 18.6g in / 27.9g out — ristretto ratio, even centered flow on the naked, balance 4, quality 4. The bright-but-resolving taste is exactly what you want to see: acidity that fades rather than lingers. Big improvement over shot 1's spraying and sour linger.

What the Numbers Say

Time is Normal at 32s. Ratio lands at 1.5 — Ristretto. Balance 4 is centered. Shot 1 had spraying on the naked and lingering sourness at grind 38; this shot at 38.5 gave clean even flow and a quick-resolving brightness. The numbers and the taste tell the same story: extraction is working.

The One Thing to Change

Lock grind 38.5, dose 18.6g, target 26–30g yield. Bean is at exactly 10 days post-roast — right at the minimum rest per roaster guidance, so expect flavor to continue opening over the next few sessions.

Clean flow, centered stream, balanced taste, no linger. The half-click finer from shot 1 fixed the distribution issue and landed you in the right place. Nothing to chase.

Bean Context

Peanut butter brittle and cocoa with a hint of lemon matches the bright-but-resolving character in the cup. At exactly 10 days post-roast this bean is just entering its window — the roaster notes dense coffees may keep improving for six weeks, so flavor complexity could develop further. No freshness concern; this is a good time to lock the recipe and let the bean evolve.

Progress

Shot 1 spraying and sour linger → shot 2 even centered flow and balance 4. Half-click finer and the naked portafilter confirmed the fix immediately — that's the diagnostic value of the bottomless working as intended.
