Notes

Flow started even across both spouts at 13 seconds. There was a bit of restriction on the left side for a few seconds then evened out and accelerated at the end leading to a longer pull than expected. Taste is good and balanced with brightness that resolves immediately

Good taste and body. Tasted good as a cortado as well but decided to change it last minute. Would have been good for a change

Great Shot

Summary

Shot 4 on this bag of Decaf Aba Mecha — grind 40, 18.1g adjusted dose, 41.7g yield in 25 seconds. Balance 4, quality 5. The shot pulled long (5.5g over your Espresso target) but the taste is the story: brightness that resolves immediately, well-balanced. Best shot on this bean so far.

What the Numbers Say

Time is Normal at 25s — low end of the range, which tracks with the accelerated finish you noted. Ratio lands at 2.3 (Normal), running longer than your 36.2g target. The lag was 10g on this pull — consistent with your known pattern on this bag — so you'd have needed to stop the pump around 31–32g to hit 36g. Taste and numbers align well: balanced flavor matches the balance 4 rating, and the quick-fading brightness is right in line with what EA washed decaf on a medium-light roast should do.

The One Thing to Change

Lock grind 40, dose 18.1g, target 33–35g yield (stop pump at 23–25g to account for 10g lag).

The extraction is clean and balanced — this is the shot you've been working toward. The only thing to tighten is yield control: stop the pump earlier to land in the 33–37g range consistently. The accelerated finish at the end is what pushed you long — stopping pump earlier catches it before it runs away.

Bean Context

Melon, milk chocolate, and graham cracker are all present-adjacent in a balanced, slightly bright shot — consistent with the bean's profile. At 15 days since roast, you're well within the EA washed decaf peak window (roughly days 4–21). The quick-fading brightness here is EA washed character, not an extraction flag. No lingering sourness, no soy sauce note — the yield reduction from prior shots is paying off.

Progress

This is a meaningful step forward. Shot 2 (balance 4) had restricted, uneven flow; this one opened clean and even across both spouts from 13s with only a brief left-side wobble. Prep is clearly improving on this bean.
