CHIZU — the atlas of coffee research
Coffee research in Indonesia
Two limits come with this count. Only 100,474 of the 190,643 searchable papers (52.7%) carry an author affiliation country. The other 90,169 (47.3%) carry none. So these 22,248 papers are 22,248 out of the 100,474 whose affiliation is known. And a co-authored paper is counted once for every country its authors sit in. Per-country counts therefore do not add up to the whole.
Indonesia is a coffee-producing country.
Check it yourself
This is not our word for it. You can run the same query against the same index.
When they were written
1970–2026
22,245 of the 22,248 papers carry a year. The rest have none.
Years before 1600 are treated as unknown. The upstream data (OpenAlex) sometimes writes 1400 when the year is missing, and that is a placeholder, not a measurement.

Which stage of coffee
Only 30.2% of the whole index carries a stage label. Of this country's 22,248 papers, 7,254 carry one. The breakdown below is about those 7,254 papers only — the rest were never candidates for it.
One paper can carry several labels, so the breakdown adds up to more than that number.
Which field
Only 75.9% of the whole index carries a field label. Of this country's 22,248 papers, 17,195 carry one. The breakdown below is about those 17,195 papers only — the rest were never candidates for it.

What language
"undetermined" means the upstream record carried no language. We did not guess one.
Knowledge is not evenly spread
22,248 papers makes Indonesia the largest of these 72 countries. The smallest, Liberia, has 1 — a factor of 22,248.
That gap does not follow where coffee is grown. Research gathers where the means to do research are, not where the coffee is. Making that visible is why CHIZU exists.
