Corrections are the most useful thing you can send. If a figure here disagrees with a source you trust, tell us which source and we will check it.

What to include

For a correction: which record, which figure, and where you are reading otherwise. A link to a producing board, a standard or a research publication is worth far more than a general disagreement, because the whole method of this site is that a figure is only as good as the document behind it.

For an origin or variety you would like added: the name, and any primary source that publishes real data on it. We add records where there is something to record.

What we do not do

We do not review or rank coffees, accept paid placements, or publish guest posts. Requests for those will not get a reply.
