I'm a new egghead and would like to build some inventory of different types of wood chunks to use for smoking. I was wondering what people used the most, and for each type of wood, what do you normally cook with it. Also has anyone tried using bourbon or wine barrel staves? Does anyone have a good online retailer for wood chunks that they recommend and that doesn't charge an arm and a leg for shipping (or has free shipping)? Thanks for the help!
