When I think of Ceylon — Sri Lanka — I think of tea, but that’s because I wasn’t alive 150 years ago. In the 1860s, coffee was the island’s most important crop. Coffee leaf rust, a fungus, put paid to the coffee, but only after a global downturn in coffee prices, and planters switched to tea. The rust, however, is not the reason the Brits drink tea rather than coffee, just one of the things I learned from Stuart McCook, who has studied the history of coffee leaf rust and what it might hold for the future.
