From the editors

This lot is no longer available at the roaster.

We last reached the roaster’s page for this coffee 0 days ago. It now returns a not-found or members-only response, so we’ve archived the buy link rather than send anyone to a dead page. The notes, sensory chart, and editorial context below remain useful as a record of what this lot offered.

Cherrybook Index (CBI)

Evidence-of-quality score, not a cup score. Methodology

46

Preliminary

Confidence2 of 7 signals on file

Score is partially shrunk toward a neutral 50; read directionally until more source families land.

How confidence affects the score

Coverage measures signal availability, not cup quality. This coffee has 30% of the signal universe on file. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 25% so one thin signal cannot carry the score on its own.

The math on file: renormalized base 41.7 shrunk to 43.8 + bonuses = 46.
