Hey guys, getting ready to smoke my first pork butt tomorrow. My plan is to smoke on rack until 160 degrees then foil for the remainder. I have heard you should spray apple juice or other liquid on it during the process. I was curious what others do with spraying the meat. I was thinking of spraying it a few times before it is foiled and then one last time before wrapping it in foil. I can't imagine spraying it once it is foiled since that would involve unwrapping it. I also heard that using apple juice from concentrate is better than just plain apple juice. Thoughts and feedback would be greatly appreciated!
