Notes

Flow started at around 8 seconds through both spouts, but quickly changed to just the left and rapid dripping on the right, then it went uneven at times on both spouts. Flavor is now on the bitter side but much more balanced than previous drinks

Drink was balanced with slight bitter notes from the coffee. Reducing the bitterness and increasing the sweetness would continue to improve the drink

Summary

Shot 21: grind 28, 18g dose, 36.4g yield, 33s — right in the Normal/Normal zone. Balance flipped to 5 (slightly bitter) and quality jumped to 4 stars, your best decaf shot yet. The flavor is landing, but the flow was messy — uneven spouts and right-side dripping point to channeling during this pull.

What the Numbers Say

Time at 33s is solidly Normal (25–35s industry standard). Ratio at 2.02 is Normal — you finally broke out of Short territory, hitting close to the 37g target (36.4g, just shy). The taste numbers tell a good story: balance 5 is slightly bitter but dramatically better than the sour-dominant shots at 34g yield. Quality at 4 is a real improvement from 1s across the last two pulls. The contradiction to flag: the channeling described in notes (right spout dropping out, uneven flow) typically means uneven extraction — yet the flavor came out reasonably balanced. That's either lucky distribution in the basket or the bitterness is masking residual sourness. Don't ignore the flow issues just because the cup was decent.

The One Thing to Change

Go 1 click coarser — grind 29 — and hold yield at 36–37g.

You went 1 click finer to 28 without logging it as an intentional change from the last recommendation (hold at 29). The result: slight bitterness and channeling. Grind 28 may be compressing the puck enough to cause uneven resistance and the right-spout dropout you noted. Back to 29 — which had even flow on both spouts last shot — and keep the yield where it is now (36–37g). The 34g yield was driving lingering sourness. You've fixed that. Don't chase the bitterness with a coarser grind yet — go back to the confirmed-flow grind first and see if the flavor lands at this yield.

Bean Context

At 9 days post-roast, this EA Washed decaf is right at the edge of its peak window (day 4–21 for EA Washed). Flavor notes are ganache, orange peel, Luxardo — the slight bitterness at balance 5 is plausible for this profile, but it's not a target. The channeling is more likely the cause of bitterness than the bean itself. Pink Bourbon at high elevation can read bright when under-extracted and chocolatey/slightly bitter when over-extracted — you're threading that needle. Grind 29 at 36–37g yield is the shot to confirm.

Progress

Quality at 4 stars is your highest rating on any bean so far — and you got there by fixing the yield issue, not by chasing the grind. That's the right instinct.
