Summary

Shot 14 on the Maomi Blend came in at 29s and a 2.09 ratio — both squarely in Normal range — but it tasted sour and light-bodied. The numbers look fine on paper, but the taste is clearly telling a different story: under-extraction. The uneven flow (left spout dominant early) points to mild channeling again, same pattern as shot 13.

What the Numbers Say

29s is Normal by both industry standard and your thresholds. Ratio 2.09 is Normal. On paper this should be a decent shot. But balance of 2 (Sour) and light body are classic under-extraction signals — and they align. The flow note confirms mild channeling again, which short-circuits extraction even when time and ratio look acceptable. Your lag was 10g this pull versus your known 6-8g Bambino baseline — slightly high but not alarming given the flow irregularity. The sour taste not lingering is the one positive: this isn't a structural disaster, just under-extracted.

The One Thing to Change

Go 2 clicks finer — move from grind 33 to grind 31. Keep dose and yield identical.

You dropped from 35 to 33 between shots 13 and 14, which was a significant jump — 2 full settings. The sourness and light body suggest you still need more resistance in the puck to slow the flow and extend contact time. Going to 31 continues the directional move. The recurring uneven flow (left-dominant) may also improve as the puck gets denser. If channeling persists at 31, that's a puck prep signal worth investigating — but start with grind first.

Bean Context

Maomi Blend is low-acidity by design — caramel, cocoa, nuts — so sourness here is almost certainly extraction, not bean character. This is not a naturally bright bean like the Ándale Market was. Sourness on a full-bodied, low-acid blend means the shot needs more from the grind. At 21 days off roast you're in peak window, so freshness isn't a factor. You're 4 shots in and still dialing — this is normal at this stage.

Progress

You've now had mild channeling in back-to-back shots — both times flow started uneven and corrected mid-shot. Worth a close look at your puck prep next pull: make sure the WDT is redistributing evenly across the full basket surface and the tamp is level before you attribute this entirely to grind.
