Start with the claim
We distinguish what can be observed in a cup from claims requiring documents, testing or traceability. Leaf shape, aroma and wet leaves cannot independently prove exact origin, age, cultivar or grade.
Choose sources deliberately
For standards and geographical protection, use the current official record. For scientific claims, consult relevant research. Books and heritage sources provide context; retailer descriptions can document market language but are not independent verification.
Keep uncertainty visible
Tasting notes describe tendencies. Traditional stories must be labeled as stories. We do not infer medical benefits from cultural use, assign authenticity scores or describe a generated illustration as documentary evidence.
Review before publication
Every profile lists its sources and labels each one plainly: an owner-supplied draft, an editorial fact-check against reliable general knowledge, or an independently checkable primary source such as a national standard or government registry entry. A profile is only marked published, and only carries a review date, once its core claims have passed at least an editorial fact-check. A smaller, growing set of profiles go further and cite a checked primary source directly — those sources are visible on the page, so you can see which kind of check a given claim rests on rather than assuming every published page has the same evidence behind it.
