Cherry's Index

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

Noted

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.

Well-regarded· sentiment 75/100

Bonanza is recognized by the community as a high-quality roaster, often grouped alongside other respected European specialty coffee brands like The Barn. Users view them as a reliable benchmark for quality, suggesting that if a home brewer is struggling to replicate cafe-quality results, the issue likely lies with the user's water or technique rather than the beans themselves.
