How Cherry’s Index is calculatedavg coverage 33% · limited data

Coverage is below 50%. Most of this roaster’s lots are scored off roaster-level signals (Reddit + YouTube) without per-lot SCA grades, Coffee Review entries, or published buyer reviews. With limited signal, scores are also pulled toward a neutral 50 baseline by the Cherry’s Index methodology, so lots can read flatter than the actual cup quality differences between them. The avg Cherry’s Index reflects general reputation more than per-lot quality.

Glitch Coffee & Roasters is widely recognized as a premier destination in the Japanese specialty coffee scene, frequently mentioned alongside other top-tier roasters like Apollon's Gold and Kurasu. They maintain a strong international presence, often appearing at major coffee festivals and being sought out by enthusiasts traveling to Tokyo. While their main shops are noted for a specific, sometimes "dark-ish" aesthetic, they are highly regarded for the quality of their beans, with some users finding their flavor profiles difficult to replicate with US-based roasters.
