At 250 g, this bag runs about 2% more per ounce than a typical 306 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.
Some listing details are missing or have limited model coverage, so the typical band shown is wider than usual.

Cherrybook Index (CBI)
Evidence-of-quality score, not a cup score. Methodology
47
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 44.6 shrunk to 46.9 = 47.

One thread author reports finding a great decaf on the 19grams website, describing it as a light to medium roast with complex, pleasant fruit notes and an orange peel-like aftertaste. Another thread author describes the 19grams advent calendar coffees as boring, noting that they tasted like chocolate, grass, and fermentation, lacked variation, and were easy to overextract with a bitter aftertaste.

…you a complex, pleasant cup with noticeable (not too pointy) fruity notes and a very nice lingering aftertaste (is it orange peel?). You can purchase it on the 19grams website, although it seems a bit hidden in there for some reason. But they also have their own webshop. So happy to finally have found a decaf that doe
