For meat - hickory, Apple, cherry, and peach. For hides - Apple, cherry, oak, ash, hickory, peach, any nut tree, but make sure it is cool smoke. Run it through a long more or less horizontal stack. I prefer wood, but good charcoal works, too. It is sometimes hard to get the fruit wood, and oak and hickory are hard to come by out here. Enjoy!; I just recently got a big smoker, have gone through 2 20 lb bags of charcoal, cooking meat. Don't care much for mesquite, personally, just my opinion; other folks swear by it.
