Here we have a surprisingly good list of fun coffee facts. I'm going to have to double-check on some of these before I start using them in my pitch, but the few obscure coffee facts I do happen to know are repeated here, so that's a good sign.
Here's one I like: "It was in 1530 that the first coffeehouse was opened in Damascus, Syria. Istanbul, Turkey opened its first coffeehouse in 1554."
Feels pretty good to be part of a tradition that has lasted for 479 years.
If you see any that aren't true let me know!
