Cherry's Index

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

80

Strong

Preliminary

Confidence33% coverage / 3 of 7 signals

Score is partially shrunk toward a neutral 50 — read directionally until more source families land. Coverage is signal availability, not cup quality; missing sources are dropped, the remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 18% so a single thin signal can’t carry the score on its own.

Onyx Coffee Lab is widely recognized as a benchmark roaster in the specialty coffee community. They are frequently cited as a standard for quality, consistency, and roast uniformity, often used as a control sample by home roasters. While some users debate their price point or specific brew recipes, they are consistently recommended, particularly for their "expressive" dark roasts and high-end, experimental offerings like Eugenioides.
