Since I have limited storage space for wood I use BBQr's Delight pellets and a BBQr's Delight Smoke Pot. Costs a little more than wood but I can have all the flavors on hand and store them in a very small space. The Mesquite, Hickory, Cherry, Oak, Apple, Pecan, Mulberry, & Alder pellets are 100% wood. They have some other flavors that have herbs and such. They even have some made from the Jack Daniels filtering charcoal.
