Notes

Flow started at around 9 seconds from the edge of the portafilter to the center, forming a few single streams first and converging at the center. A few sprays. Taste was bright that resolved quickly with a balanced overall flavor

Great Shot

Summary

Shot 7 on the Decaf Aba Mecha (bag 25) — clean border-to-center flow on the naked PF, hit your Espresso target almost exactly (36.3g vs 36.6g target, 26s within the 25–30s window), balanced flavor with brightness that resolved quickly. Grind 40 is working.

What the Numbers Say

Time 26s (Normal), ratio 1.98 (Short) — both solid. Balance 4 and quick-fading brightness on an EA washed decaf is exactly what you want; no lingering sourness, no over-extraction signal. Lag 9g noted — normal for this machine and bean. The naked PF border-to-center flow with a few minor sprays is healthy extraction, not a prep flag.

The One Thing to Change

Lock grind 40, dose 18.3g adjusted, target 34–38g yield.

Seven shots in, grind 40 has now produced balance 4 with clean flow twice consecutively. The recipe is dialed in — hold it.

Bean Context

Melon, milk chocolate, graham cracker profile is showing up as brightness that resolves cleanly — consistent with the bean's notes and EA washed processing. At 24 days post-roast this bag is in its prime window (4–21 day range shifts later for EA washed; roaster recommends 10+ days and you're well into that). No freshness concerns.

Progress

Shots 6–7 on this bag are back-to-back balance 4 with clean flow — the right-side WDT bias work from earlier bags is clearly carrying over. Solid consistency.
