Roasterlist is a working dataset of 483 active UK coffee roasters, with editorial layered on top. This page sets out how the directory is compiled, how the descriptions are produced, and how often the whole thing is reviewed.
The directory tries to include every independent coffee roaster operating in the UK. The four conditions for inclusion:
If a roaster meets these conditions, they go in. We don't curate. We don't filter for size, fame, age, or our own taste.
Each roaster on Roasterlist has its own profile page. The profile is built from two layers.
We capture a consistent set of attributes for every roaster, where we can verify them: founding year, location, roasting machine, team size, roast tendency (light to dark), origins they source, sourcing approach (direct trade, relationship coffee, broker), certifications (B Corp, Organic, Fair Trade), awards. Attributes that can't be verified from public sources are left blank rather than guessed.
Every active roaster has a written description that captures what makes them distinct. The drafting process for each one:
Descriptions are written, not generated from templates. We don't lift marketing copy. We don't paraphrase Wikipedia. If two roasters end up with similar-sounding descriptions, we rewrite at least one. The aim is a description a friend would find useful.
Each roaster is assigned to one UK region. The current approach is mixed: large urban areas use the city as the region (London, Manchester, Bristol, Edinburgh, Glasgow), and outside those, the county or recognised geographic area is used (Cornwall, Yorkshire, the Highlands).
A region page is generated automatically when at least three active roasters are tagged to that region. Below the threshold, the region exists in the data but isn't published as a page. This avoids thin pages of one or two roasters that don't help anyone.
Region boundaries are an editorial judgement, not an official standard. We're aware the current mix of cities and counties isn't perfectly consistent and we plan to standardise it as the dataset grows.
A directory page (for example "UK Coffee Subscriptions" or "Decaf Coffee Roasters") lists roasters that share an attribute. The attributes themselves are recorded on each roaster profile from public information: a roaster appears on the subscriptions directory because they actually run a subscription, not because we chose to feature them.
If a roaster's offering changes (they drop a subscription, become B Corp certified, stop selling decaf), we update the underlying record and the directory pages update with it.
A small number of pages on Roasterlist involve editorial ranking, not just structural ordering. These are the curated guides ("Best UK Decaf Coffee 2026", "Best UK Coffee Subscriptions") and any list with the word "best" in the title.
For these, the page itself shows the criteria we used, the weighting we applied, and what we excluded. The standard layout includes:
If a roaster on a "best of" list is also an affiliate partner, the page declares the affiliate relationship in line. The affiliate status is never the reason a roaster appears.
Profile data is reviewed in three ways.
Continuous. When a reader, a roaster, or a search-result anomaly flags something, we check it and update if needed. Most updates land within a week.
Quarterly. Every quarter, we run a sweep across the dataset for closures, rebrands, ownership changes, new B Corp certifications, and similar status changes that we wouldn't catch otherwise.
Annually. Once a year, we audit the full dataset. The annual audit checks every active roaster's website is still live, their region is still correct, their listed attributes still match their public offering, and their description still reflects what they're doing today.
Each profile carries a "last reviewed" date so readers can see how recently it was checked.
Roasterlist is a directory and an editorial layer, not a marketplace. We don't sell coffee, take orders, or run prize draws. We don't operate a paid membership for roasters. We don't host user reviews or ratings. Suggestions and corrections come through email; they're moderated and processed manually.
Three things we don't claim to be.
We haven't tasted every coffee. The descriptions are about what the roaster is, not what their coffee tastes like. A description tells you what to expect from the roaster's overall position, not whether you'll personally enjoy the cup.
We're not a barista guide. The directory is about roasters, not cafes. Some roasters run cafes; that's part of their profile. But "best coffee shop in [city]" is a different question that we don't answer.
We're not exhaustive yet. The UK roasting scene changes constantly. New roasters launch, others close quietly. If you know one we've missed, the suggest a roaster page is the fastest way to tell us.
