Our methodology

CoffeeComparer exists to answer one question honestly: which UK specialty coffee is genuinely good value? Here's exactly how we gather the data behind every page, so you can judge it for yourself.

Where the data comes from

We collect product data directly from each roaster's own online shop — prices, bag sizes, roast level, origin and availability. Most UK specialty roasters run on Shopify, so wherever possible we read the shop's structured product data rather than scraping page text, which keeps prices and variants accurate. We only add roasters that sell whole-bean or ground specialty coffee.

How we make it comparable

Bag sizes vary — 200g, 250g, 350g, 1kg — so a sticker price tells you little. We normalise every coffee to a price per kilogram, calculated from the cheapest in-stock size, so a 250g bag and a 1kg bag can be compared on equal terms. We also surface the real "from" bag price, because that's what you actually pay.

Each product is validated structurally before it's listed: it must have sensible weight-based pricing (or valid unit pricing). Equipment, merchandise, gift cards and subscriptions are filtered out so you only compare actual coffee.

How we rank

Listings and "best" guides are ordered by price per kilo — best value first — and nothing else. Ranking is never influenced by whether a roaster pays us commission. Roasters with no affiliate programme appear exactly the same as those with one. See how we make money for the full disclosure.

How often it updates

Prices and availability refresh roughly hourly, and we re-collect each roaster's full range regularly. Coffee is a moving target, though — roasters change prices, sell out, and rotate seasonal lots. We always link straight to the roaster, so treat our price as a guide and confirm the final figure on their site before buying.

Limits we're honest about

Not every roaster publishes roast level or origin, so those fields aren't always complete — we show them where we have them and never invent them. We don't take payment for inclusion, we don't run sponsored placements, and we don't publish review scores we haven't earned. If something looks wrong, it's a bug — tell us.
