Broad comparison: 62nd percentile of 168 washed single-origin lots (other named varieties, retail bags); USD listings; roast unlisted 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.

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.

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 84.1 shrunk to 69.6 + bonuses = 66.

Cult favorite· sentiment 88/100

Two independent Reddit comments give Proud Mary Coffee strongly favorable marks. A Portland customer praised its food and fun coffees and named Ghost Rider a favorite under $20. Another visitor said a Proud Mary coffee had impressed them more than a consistently good local comparison.

    The Proud Mary in Portland has some insanely good food and really fun coffees. They’ve recently cut down on their specialty pour over menu which may just be seasonal. I’ve never seen this much selection of bags and tins here though. Ghost Rider is my favorite sub $20 from them

    Regarding heart vs proud Mary — I was in Portland not all that long ago and had both. Heart i think has a really high level of consistency but it’s rare that I’m wowed by a coffee (and shot) like I was at Proud Mary. Just my 2c

The shop features a wall-mounted freezer system for storing multiple coffees, custom-modified grinders, and a specialized dosing system that allows for precise, multi-functional brewing.

Inside this video

From Brian Quan and Proud Mary Coffee:

“It's a freezer mounted on the wall. It can hold 12 different coffees.”
“The fun thing on this one is a custom collar here with millimeter scale. I wasn't a fan of the degrees. I like the millimeters.”
“This is the tightest setup here. Look at that. That is so cool.”
