About Caffeine.supply

What this site is, how we source and rate coffee, and why every "Buy" link points somewhere else.

What Caffeine.supply Is

Caffeine.supply is an independent index of specialty coffee — currently 600+ coffees from 100+ US roasters. We don’t roast, warehouse, or ship coffee ourselves. Instead we catalog what roasters already sell, then make it filterable, comparable, and rankable in ways a single roaster’s own storefront never will be: by origin, process, roast level, elevation, certification, price, and more.

Every coffee page links out to the roaster’s own store to buy. We’re a discovery layer sitting on top of the specialty coffee market, not a retailer.

How We Source Data

Origin, process, roast, elevation, tasting notes, pricing, bag sizes, and certifications are compiled from each roaster’s own published listings and normalized into one consistent schema, so a Kenyan washed coffee from one roaster can be meaningfully compared to a Colombian natural from another. The catalog is refreshed periodically; coffees that go out of stock are labeled "Sold Out" rather than deleted, so rankings and collection pages stay useful as a historical record, not just a live shopping feed.

Rating vs. SCA Score — What’s the Difference?

Two different numbers show up on coffee pages, and we keep them deliberately separate:

Rating is Caffeine.supply’s own editorial score (out of 5), used to sort and surface coffees across the site — in rankings, collection pages, and the homepage grid. It reflects our own curation, not a certified lab or panel process.

SCA Score, shown only on coffees that have one, is the Specialty Coffee Association’s official 0–100 point cupping-protocol score, as reported by the roaster. It’s the industry-standard measure of cup quality — 80+ is the threshold for "specialty grade." See our glossary entry on SCA Score and the highest SCA-scored coffees for more.

How Rankings & Collection Pages Are Built

Every ranking (best value, highest-rated, highest SCA score, and 30+ more) and every facet collection page (by origin, process, roast, certification, price band, and others) is generated from the same underlying dataset using a fixed, disclosed filter and sort — not manual picks or paid placement. If a coffee qualifies by the stated criteria, it appears; when it’s sold out, it’s labeled, not hidden.

Frequently Asked Questions

Does Caffeine.supply sell coffee?
No. Caffeine.supply is an independent index and discovery site — every "Buy" link on a coffee page goes directly to the roaster’s own store. We don’t take a cut, hold inventory, or ship anything ourselves.
Is the star rating a certified SCA cupping score?
No, and we’re explicit about that distinction. The rating shown on each coffee is Caffeine.supply’s own editorial score, used for sorting and browsing. A separate "SCA Score" field — shown only on the coffees that have one — is the Specialty Coffee Association’s official 100-point cupping-protocol score, as reported by the roaster. We keep the two labeled separately rather than blending them into one number.
Where does the coffee data come from?
Origin, process, roast level, elevation, tasting notes, pricing, and certifications are compiled from each roaster’s own published listings and product pages, then normalized into a consistent format so coffees can be compared, filtered, and ranked side by side.
How often is the catalog updated?
The dataset is refreshed periodically as roasters add new coffees, retire seasonal lots, or change pricing. Sold-out or discontinued coffees are labeled rather than removed, so rankings and collection pages stay historically useful.
How are the Rankings and collection pages built?
Every ranking and facet page (origin, process, roast, price band, certification, and more) is generated from the same underlying dataset using a fixed, disclosed filter — there’s no manual curation or paid placement involved in what qualifies or how it’s sorted.
