Coffee Science: Coffea Arabica Origins and Genetics

Coffee research papers focused on the origins of C. Arabica and related genetics

These are a set of article PDFs about coffee varieties, the origin of Coffea Arabica and other types, coffee genetic diversity and such. There are also a few historic documents, the fascinating 1833 tract about coffee in Havana, the work of the FAO in Ethiopia in the mid 1960s, and a trip to Gesha Ethiopia 1936.

(There are also articles about coffee culture and some papers characterizing local coffee in a system of geographic appellations below.)

This is one of 5 groupings of articles. Head back to the main Coffee Science page for links to the other sections!

I have collected over time from a variety of “open source” sites, shared directly with me, or other public archives. I am pretty fascinated with the research work focused on coffee and related issues. I am also not a scientist, economist or involved in Academia. I have an MFA!

If you are an author or are aware that any of these papers should not be available here, please contact me and I will respond promptly. I think it’s possible some work here that was emailed direct to me might not have been published for public access, but it’s hard to tell by the file itself. So please just communicate with us: [email protected] -Thompson



Coffee Culture and History

This is a slim section of articles, avoid all the usual hooey and myth from the usual coffee books.

The article on Buna Qalaa, roasting whole coffee cherry for an amazingly rich milk drink, is super interesting. (I have enjoyed this in rural Ethiopia myself, served usually for special occasions like weddings). I also include a couple papers about regional coffee indicators, GIS stuff.

The H Renes article about Aceh coffee is amazing too!

I repeat a couple old archival docs from other sections here.
