Trim excess fat from top of butt and score fat cap on bottom of butt.
Rub the butt liberally on all sides for maximum bark.
Smoke at 225-250 with a mix of hickory and fruit wood for at least 5 hours.
If using a grill with indirect heating, rotate the butt every hour so each side cooks evenly.
Spray every hour for first 3 hours with apple juice and sprinkle more rub.
Place pork butt in aluminum pan and wrap tightly with foil. Place back in smoker (or oven) until internal temperature hits 200. For a 10lb butt this usually takes me 10 - 12 hours.
Let rest for an hour before pulling.
Notes
When to wrap the butt is more of a personal choice than an exact science. I like to wrap after the butt has smoked for about 5 hours.Wrapping the butt protects the color of the butt, prevents it from taking on too much smoke flavor, saves juices and speeds up the cooking process.
