Loc Rung - Vietnam
Expect Papaya, Jackfruit, and Oolong Tea from this natural lot.
Lam Dong, VN · Natural

Roaster · Chattanooga, TN
14 lots in stock, mostly Yemen, Colombia and Ethiopia.
Coverage is below 50%. No Reddit or YouTube roaster-level signal is on file. 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 reflects the limited per-lot evidence plus the methodology's neutral baseline.

Per-lot signals (averaged)
Vary across lots; averaged over 14 in-stock lots.
Bonuses earned (per lot)
Base components are renormalized over whatever signals are available for each lot. SCA + Coffee Review are capped at 40% combined to keep the cupping story from dominating. Bonuses (accolades, awards, editorial coverage) and freshness decay are applied on top.
