It can be hard to remember, but coffee isn’t just a delicious liquid drug — at its most basic level, it’s a plant that people sow, grow, and harvest. There are plenty of kinds of coffee, too, and none as significant on the global market as coffee canephora, also known as robusta. That’s one of the hardiest, most caffeinated varieties of coffee. And while its counterpart arabica gets more attention for having a wider flavor profile, robusta is far less likely to be classified as “specialty” coffee. Both kinds’ global popularity is thanks to Europe’s carving up of coffee-growing regions such as East Africa and Southeast Asia for export: The Dutch taking coffee to Indonesia and enslaving locals is how we got the now-common term “java,” for example.
