If you have one that is adjustable to a really fine grind, it's worth a try! If it works, make sure you only use it for coffee only, though, unless you want to have coffee-flavored pepper after that. Or if you've already used it for pepper and want to start using it for coffee, grind dry rice to clean it, I don't think you should wash it. If it doesn't work, I've read good things about Sozen Turkish grinders.
