Notes

Flow started even on both spouts at around 9 seconds, then started dripping on the right spout a few seconds later, but resolved after about 5 seconds, with even flow the rest of the shot. Bright punch of flavor at first but resolved quickly with a balanced taste. some Crema.

Slightly bitter after taste. It reminds me of chocolate. Latte art was a big blob with too much foam almost cappuccino

Analysis

AI Analysis

Great Shot

Summary

Shot 64 is your best pull on Unicorn Blood — 34 seconds, 38.1g yield, balance 4, 4 stars. Flow had a brief right-spout dropout around 9–14 seconds but self-corrected and ran even the rest of the way. Taste confirms it: bright upfront hit that resolved cleanly into balance. This is the target.

What the Numbers Say

Time and ratio both land squarely Normal. Balance 4 matches the clean finish you described — the quick-resolving brightness is the berry character on this bean, not an extraction fault. Notes and numbers are fully aligned here.

The One Thing to Change

Lock grind 40, dose 17.5g, target 36–40g yield.

The brief right-spout dropout self-corrected within 5 seconds and didn't affect taste — that's a minor puck imperfection, not a problem to chase. Hold everything as-is and keep the WDT hard cap at 30 seconds.

Bean Context

At 42 days post-roast the bag is past peak on a medium-dark washed bean, but this shot shows it's still pulling well. Freshness decline on this roast level is gradual — you likely have a few more good shots left, but expect the window to close soon. The dark chocolate, caramel, and berry notes are coming through exactly as described.

Progress

This bean gave you five consecutive problem shots — slow, channeling, uneven flow — before grind 40 cracked it. The WDT discipline is what made the difference. That's a real skill being built.
