Cherry's Index

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

Sparse signal

Confidence23% coverage / 2 of 7 signals

Score is heavily shrunk toward 50; treat as a placeholder until more sources arrive.

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 43% so one thin signal cannot carry the score on its own.

Taste this against three others Cherry picks.

Brew a set side-by-side. Cherry varies the picks along axes that pair with this lot; origin, process, roast, or producer; so you learn the difference, not just drink four good cups.

About PERC Coffee

Community reputation · Reddit

Cult favorite· sentiment 85/100

PERC Coffee is well-regarded by specialty coffee enthusiasts on Reddit, particularly noted for standout single-origins like their Ethiopia Benti Nanka (frequently praised as a massive blueberry 'fruit bomb') and strong value offerings like their Juggernaut blend. Community members often highlight their accurate tasting notes, fun flavor profiles (such as chocolate raspberry cake notes in their PNG offerings), and appreciation for their periodic flash sales.
