At 250 g, this bag runs about 2% more per ounce than a typical 308 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 this exact profile 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 lot in the comparison class, so it moves as the catalog does. 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.

Cherry's Index

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

62

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 70.0 shrunk to 61.5 = 62.
