How Cherrybook Index is calculatedavg coverage 23% · limited data
Coverage is below 50%. Available roaster-level evidence comes from Reddit. Per-lot evidence from SCA grades, Coffee Review entries, and public on-shop product ratings is limited across the catalog. With limited signal, scores are also pulled toward a neutral 50 baseline by the Cherrybook Index methodology, so lots can read flatter than the actual cup quality differences between them. The average Cherrybook Index therefore leans more heavily on roaster-level reputation than per-lot quality.
