Cajamarca, PE · Washed

Roaster · Chicago, IL
5 lots in stock, mostly Peru, Colombia and Guatemala.
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.

Per-lot signals (averaged)

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.

Two Reddit contributors describe very positive experiences with Halfwit Coffee Roasters. One ranks Halfwit among their top three. Another says Halfwit's Yirgacheffe had an explosion of intricate flavors and that they strongly preferred it in a side-by-side comparison with instant coffee.
Freaking halfwit is top 3 in my book! Second only to Rwandan Bourbon, change my mind!
So I decided to test it out. I made a pourover of Halfwit's Yirgacheffe, a roaster out of Chicago. I made a cup of his instant coffee next to it. To me, the difference was HUGE. The instant was just dishwater, while the yirg had an explosion of intricate flavors. I put them into the same cups and mixed them up so even.
