Score is heavily shrunk toward 50; treat as a placeholder until more sources arrive.
How confidence affects the score
Coverage measures signal availability, not cup quality. This coffee has 23% of the signal universe on file. Missing sources are dropped, remaining weights are renormalized, and the result is shrunk toward a neutral 50 baseline by 43% so one thin signal cannot carry the score on its own.
The math on file: renormalized base 67.2 shrunk to 59.9 + bonuses = 66.

Three Reddit contributions give a mixed-to-positive view of Onyx Coffee Lab. One poster said a $40 Onyx bag was not better than coffee they roasted at home. In another thread, a commenter called Monarch their favorite from Onyx and an easy first recommendation for espresso. A home roaster wrote that an Onyx Kenyan AA control sample was much more uniform in roast degree and bean size than their own batch, and said the consistency made them jealous.

So I went crazy and spent $40 on a bag of this Onyx coffee just to see what all the hype is about. Honestly it isn’t any better than the stuff I can roast at home. Am I missing something?

Monarch is my favorite from Onyx. For anyone that is looking for an easy recommendation or go-to espresso, its usually my first pick.

...or there in my dosing cup that I remove before grinding. While the roast looks uneven, it tastes phenomenal! When compared to a bag of Kenyan AA beans I bought from Onyx as a control sample, I found their beans are much more uniform in roast degree and size. Granted these came from a different farm, but the consiste
