Preheat the smoker to 270 degrees F. I like to use a mix of oak and cherry woods for smoking.
Trim any excess fat from the pork. Generously season all sides of the wings with the Rib Rub, or your favorite seasoning.
Place the wings on the smoker, close the lid, and smoke for about 1 hour, or until the internal temperature of the wings is about 155 degrees F.
Remove the wings from the smoker.
Place 1 tablespoon of butter on a large piece of tinfoil sprinkle with about 2 tablespoons of the brown sugar. Place one wing on top of the butter/sugar. Repeat with the other wing.
Sprinkle the tops of the wings with about 1 tablespoon of brown sugar, each.
Form the tinfoil around the wings to form a bowl. Pour the beer around the wings. Be careful not to pour the beer on the wings.
Securely wrap the tinfoil around the wings. Place back on the smoker. Increase the smoker heat to about 300 degrees F. Smoke for about 45 minutes, or until the internal temperature of the wings is 205 degrees F.
Remove the wings from the tin foil and place directly on the smoker. Reserve the cooking juices. Baste the wings with BBQ sauce and cook for about 5 to 8 minutes. Remove and baste with the reserved juice before serving.
