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.

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 75.7 shrunk to 64.8 = 65.

One thread author expresses excitement to try four new bags from Traffic (Marcelo Flavio Competition Lot, Oma Fontule, La Colmena Geisha, and Olympus) after previously having Love Buzz. Another thread poster states that Traffic's beans are very good with clear tasting notes and amazing smells, comparing them favorably to other brands they have consumed.

4 new bags just arrived in the mail from Traffic. It’s 7 PM and it’s taking every ounce (or gram?) of restraint not to brew a cup right now. Who else is a fan of Traffic? I’ve only had Love Buzz before, excited to rip into these bags. Here’s what’s on deck: https://www.trafficcoffee.com/products/marcelo-flavio-competit

I’ve been drinking a lot of different Traffic beans lately and every single one is so good, every tasting note is so clear, they smell amazing. I don’t understand how. I’ve always bought nice beans. The others I’ve been drinking lately are monogram and process. I lived in London and drank scenery, Dak, dark arts and ot
