I'm pretty new to this smokin thing and have a question about wood. I have an offset smoker and up until now have pretty much used charcoal exclusively. I recently ran into a fellow with a saw mill that said I could have all of the oak and hickory slab wood I wanted. I picked up a pickup load, cut it up and piled it. Here's my question. quite a bit of it has some amount of bark on it. Will that have any negative affect on the taste of the meat? Do I need to knock ALL of the bark off the wood before I put it in the smoker?
