Broad comparison: 20th percentile of 15 natural single-origin lots (other named varieties, small bags); across markets in stock right now.
This group broadens origin, roast or selling market to find enough lots. It does not qualify this coffee for a value recommendation.

At 150 g, this bag runs about 8% more 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
52
Sparse signal
Confidence1 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 5% 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 88% so one thin signal cannot carry the score on its own.
The math on file: renormalized base 65.0 shrunk to 51.9 = 52.

Brew a set side-by-side. The picks vary along axes that pair with this lot; origin, process, roast, or producer; so you learn the difference, not just drink four good cups.
