Questionable.
Do coffee plants grow on the Arabian peninsula? I believe they grow in tropical highlands – don’t think there are many of those in Arabia.
Arabica coffee (Coffea arabica) actually comes from the mountains of Ethiopia, and it prefers cooler temperatures (but where it never freezes). It’s mostly grown in tropical highlands. Yemen has mountains over 12,000 feet, which is why coffee was cultivated there.
Robusta coffee (Coffea canefora), which is more bitter but has more caffeine, grows in tropical lowlands. It’s the main coffee grown in Brazil.
Now this post is why I can’t ever leave the Dope. I learn stuff here. I never knew there were two types of coffee beans, with such different properties.
I’ve recently had to learn a lot about coffee since I’m working on a new Museum of Coffee scheduled to open in Panama later this year. Last year I did an exhibit on coffee for a visitor center in Panama’s western highlands. (Panama doesn’t grow a lot of coffee, but it does produce the most expensive variety in the world, Geisha. (The name has nothing to do with Japanese geishas - it’s named for a district in Ethiopia.)
Nearly all coffee you would buy for its taste is arabica.
Robusta is used mainly for instant coffee and filler, although it is also used for espresso.
Strongest coffee I ever had was in Iceland. When ordered there instead of a cup you get a carafe with about a liter in it, kind of like some coffee shops here do. Now, being in the Navy, I knew something about coffee (see post 21) and, not being snipes, never did the salt thing but we did make it strong. After a carafe (or a bit less) of Reykjavik coffee about one in the afternoon, I’d still be vibrating at ten that evening.
