At 1000 g, this bag runs about 14% less per ounce than a typical 288 g bag; that is pack size, not the coffee.

How this estimate works

A statistical model, refit weekly across the in-stock catalog, estimates what a coffee with these listed attributes typically sells for per ounce. Each multiplier compares one trait against the average lot in this market; the roaster line covers brand and sourcing together, which this model cannot separate. Bag size is shown separately, priced at the rate observed across sizes of the same coffee, because it says nothing about the coffee itself. The distribution counts every in-stock listing in the comparison group, with at least 15 listings from three roasters and no roaster supplying more than 60% of it. Decaf, blends, variety segments, processing families and bag formats stay separate. Origin, roast and selling currency can broaden as the group label indicates. Prices are converted to USD per ounce; shipping and differences in tax treatment are not adjusted. The model reads listed attributes only: the quality of the specific lot in the bag is not observable, so a price above the typical band is not evidence of overpricing.

Cherrybook Index (CBI)

Evidence-of-quality score, not a cup score. Methodology

64

Sparse signal

Confidence2 of 7 signals on file

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 81.0 shrunk to 67.8 + bonuses = 64.

About Ona Coffee

Community reputation · Reddit

Well-regarded· sentiment 84/100

Four independent Reddit threads give Ona Coffee a favorable picture. A first-time drinker said the coffee would not be their last, another called the Raspberry Candy blend an all-time favorite, and a separate poster listed Ona among roasters they had tried and enjoyed. A Liberica drinker described an aromatic cup with smoke and tobacco notes while distinguishing it from dark-roast flavor.
