Notes

Balanced shot with slight bright and bitter notes. Taste reminds me of chocolate. Flow was slightly fast but even across both spouts throughout. More lag than usual which might indicate some minor channeling

Very balanced drink without harsh notes. A bit too much foam still, big bubbles and blob latte art

Great Shot

Summary

Shot 66 — grind 40, 17.5g adjusted dose, 39g yield, 24 seconds, balance 4, 5 stars. Fast time but even bilateral flow throughout, chocolate notes, and a balanced finish. Your best shot on this bag.

What the Numbers Say

At 24 seconds this lands in the Fast band — below the Normal floor of 25s — but the taste tells a different story entirely: balance 4, 5 stars, chocolate notes, clean finish. Fast time with even flow and no taste penalty is a common signature of a well-prepped puck on a medium-dark bean where resistance is naturally lower. The 8g lag is normal Bambino behavior — not channeling. Your own note flagging it as possible channeling is the one thing to set aside here: even bilateral flow throughout contradicts that read, and the taste confirms it.

The One Thing to Change

Lock grind 40, dose 17.5g, target 37–41g yield.

This is your cleanest shot on Unicorn Blood — balanced, chocolate-forward, 5 stars. The fast time is a non-issue when flavor is this good. Hold everything exactly here.

Bean Context

Dark chocolate from a medium-dark washed Honduras/Guatemala blend is textbook on-profile. At 43 days post-roast the bag is in 'use soon' territory but clearly still has life — this shot shows no staling signs. Finish the bag at these parameters.

Progress

Shot 64 locked the recipe, and shot 66 just confirmed it with a 5-star pull. The WDT hard cap is doing its job — two clean shots in a row with no channeling drama is the pattern you've been building toward.
