How CoffeeLabAdvisor knows what it knows

Every answer says what we actually know

Most sites make every product sound intimately known. We would rather tell you which of these four things is true — the same rule the CoffeeLab Awards are decided under.

Independently evaluated

We evaluated it under our published methodology: a review, a profile, a brand hub, a pairing page or an award. The Advisor sends you to that page and adds what it is best suited for.

Specification verified

We read and dated the maker's (or the listing's) specification. We say what it is and who it may suit — each line derived by a written rule from a field on that specification — and we say plainly that we have not evaluated it.

Identified

We can identify it and say where it appears on our site — a listing on a guide, a roaster's bag on our roster, a machine named on an award page. Nothing more.

Not yet evaluated

We have not evaluated it and it is not something we can identify. We say so, show the nearest things we do cover, and put it on the list of what we write next.
