At 340 g, this bag runs about 2% 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.
Some listing details are missing or have limited model coverage, so the typical band shown is wider than usual.

70
Noted
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 83.9 shrunk to 69.5 = 70.

About JBC Coffee Roasters
Community reputation · Reddit
Cult favorite· sentiment 85/100
Six live Reddit sources are predominantly positive about JBC. Contributors call the roaster amazing and great, describe a Gesha as unusually memorable, praise a fruit-forward Ethiopian, and report a floral and fruity Nano Genji espresso with chocolate on the finish. Two posts also describe JBC beans as high quality and complex, though one brewer sought help reproducing the listed tasting notes.

I am also happy to vouch for JBC, they are a great roaster. I lived in Madison for several years and would stop by their offices every now and then (them and Colectivo were my primary source of beans during my time in Wisconsin), although my most recent purchase with them was the Ninety Plus Gesha Estates #227.

My first step into coffees of complexity was with JBC's (Madison, WI) Refisa Ethiopia and now Bella Carmona, each brewed in a French press. I gave my son (age 13) a taste, and he likes it. Now, he doesn't like the Starbucks Cold Brew or Iced Coffee from the grocery because it tastes like 'nothing' to him now. His mom l

I ordered Ethiopian's this month from heart hydrangea and JBC and JBC might be the best of the three. I regularly order great Ethiopian coffees from top roosters and I was pleasantly surprised by JBC. It doesn't get as much buzz on here but when I did a little research they have good roots and great reputation. Some ha

I’ve been making what I believe to be some pretty damn good cups of coffee lately with some high quality beans (I’ll be referencing Buna Boka #1 from JBC Roasters here), but I’m missing those tasting notes that are on the bag.
