Cherry's Index

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

Strong

Preliminary

Confidence28% coverage / 2 of 7 signals

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. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 30% so one thin signal cannot carry the score on its own.

Cult favorite· sentiment 85/100

Proud Mary is widely recognized as a top-tier roaster, frequently mentioned alongside other industry leaders like Onyx and Tim Wendelboe. While they are highly regarded for their "deluxe" and exotic coffee selections, some customers find their cafe pricing and recent bag size changes to be steep or frustrating. There was one report of a recent decline in roast quality for subscription beans, but the company's responsive customer service in that instance was noted.
