At 408 g, this bag runs about 3% less 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.

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 79.1 shrunk to 66.8 + bonuses = 62.

Two Reddit posts praise Sump. One poster says they enjoyed trying it; another calls a Costa Rica coffee exceptional, juicy, full, easy to brew, and highly recommends it.

Finally got to try Sump from St. Louis. Enjoyed it but I used a little too much water. Any thoughts on Sump, their coffee, or ways to prepare it?
- r/Coffee · 5↑ · [STL] Coffee Recommendation: Sumps's Costa Rica Las Lajas
For all you STL peeps, Sump's most recent batch of Costa Rica is exceptional. Very juicy, very full. Very easy to brew at home on a V60, too. I'm doing 25:350 at a 14 grind (on a Baratza), 50g bloom, water in by 1:45 and dripped by 2:20. If you can pick up a bag or find a cup in a local shop, I highly recommend trying.
