What gets listed
The directory tries to include every specialty decaf coffee available to UK buyers. The four conditions for inclusion:
- Decaffeinated. The coffee is sold and labelled as decaf. We don't include low-caffeine or half-caf blends.
- Available in the UK. The coffee is sold by a UK-based roaster, retailer, or supermarket and can be bought from a UK address.
- Specialty grade. The coffee is positioned as specialty by the roaster: single-origin or named-blend, with origin and decaf method declared. Mass-market instant and pre-ground supermarket lines are listed separately in the supermarket section.
- Discoverable. The roaster has a working website or current retail listing. We can't catalogue a coffee we can't verify.
If a coffee meets these conditions, it goes in. We don't curate by taste. We don't filter by roaster size or fame.
How a coffee is classified
For every coffee on decaffeinate, we capture a consistent set of attributes from public sources (the roaster's website, the product listing, or the supplier where stated):
- Roaster and product name
- Decaf method (see the classification scheme below)
- Origin (country, region where stated)
- Variety and processing (washed, natural, honey, anaerobic, where stated)
- Format (whole bean, ground, capsule, instant)
Fields that cannot be verified from public sources are left blank rather than guessed. If a roaster lists a coffee as "decaf" without naming the method, the method field is recorded as Unknown.
The decaf method classification
Decaf coffee is produced by one of a small number of industrial processes. decaffeinate classifies each coffee under one of these:
- Swiss Water Process. Solvent-free water-based decaffeination, branded process, certified by Swiss Water Decaffeinated Coffee Inc.
- Mountain Water Process. Solvent-free water-based decaffeination, Mexican origin, branded by Descamex.
- Sugar Cane (EA) Process. Ethyl acetate derived from sugar cane fermentation, predominantly Colombian.
- CO2 Process. Supercritical carbon dioxide extraction, no chemical solvents.
- Chemical solvent processes. Methylene chloride (MC) or ethyl acetate from non-sugar-cane sources. Listed by name where declared; otherwise grouped under Chemical.
- Unknown. Where the roaster has not declared the method publicly. We don't infer.
Method classification is based on what the roaster states publicly. Where a roaster names a specific branded process, we use that label. Where they describe the process generically, we map to the closest category and note the source.
How descriptions are written
Each coffee on decaffeinate carries a short description. The drafting process for every one:
- Read the roaster's product page in full
- Note the origin, method, processing, and any sensory notes the roaster declares
- Capture what makes the coffee distinct (single estate, unusual processing, specific decaf method, a roaster's particular reputation)
- Write a short description in plain language
Descriptions are written individually, not generated from a template. We don't lift marketing copy. We do quote roaster-supplied tasting notes when they are useful; quoted text is attributed inline.
How "best of" lists are built
A small number of pages on decaffeinate involve editorial ranking, not just structural ordering. These are the curated guides ("Best UK decaf coffee", "Best supermarket decaf") and any list with "best" in the title.
For these, the page shows the criteria, the weighting, and what we excluded. The standard layout includes a front-loaded answer, the explicit criteria, what we excluded and why, and an author byline with a last-updated date.
Where a featured coffee is also linked via an affiliate relationship, the page declares the affiliate status in line. The affiliate side is never the reason a coffee appears.
How often the data is updated
Three review cadences.
Continuous. When a reader, a roaster, or a search anomaly flags something, we check it and update if needed. Most updates land within a week.
Quarterly. Every quarter, we sweep for coffees that have been discontinued, rebranded, or moved between roasters, plus any method or origin changes the roaster has declared.
Annually. Once a year, we audit the full dataset. Every active coffee is checked against its current product page; any stale entry is marked inactive or updated.
What decaffeinate is not
decaffeinate is a directory and an editorial layer, not a shop or a tasting platform. We don't sell coffee, take orders, or run subscriptions. We don't operate paid placements for roasters. We don't host user reviews. Suggestions and corrections come through email and are processed manually.
What we don't claim to be
Three honest limits.
We haven't tasted every coffee. Descriptions cover origin, method, processing, and roaster context. They are not tasting reviews. Sensory notes, where present, are attributed to the roaster.
We don't certify methods. When we record a coffee as Swiss Water or Sugar Cane EA, we are reporting what the roaster has declared, not independently verifying it.
We're not exhaustive yet. The UK specialty decaf scene moves. New coffees launch every week, others quietly disappear. If you know one we've missed, email [email protected].
