Soak the wood chips in water at least an hour before starting up the grill.
To get the grill started, put a drip pan filled with beer on one side of the grate, and the coals on the other. You will be cooking the birds over the drip pan.
The Rub
If you have a small food processor, put everything in the bowl and mix thoroughly.
If you don't have a small food processor, then put all ingredients in a non-reactive bowl and mix everything thoroughly. Break any lumps of brown sugar using the back of a spoon, or use your fingers.
Use about 2 to 3 tablespoons of rub for every 2 pounds of chicken.
The Glaze
Stir the glazing ingredients until you have a smooth sauce.
Flatten Birds
Cut out the spine,
Blot dry using paper towels,
Fold it open and push it flat,
Stick in two steel skewers crosswise to keep it flat,
Use your fingers to rub the dry rub on the skin and all the crevices. Make sure that you put some in the cavity of the chicken, too.
Put the chicken skin side down, legs facing the coals over the drip pan, and roast for a half an hour
Turn skin side up, legs facing away from the coals, and start putting the glaze on. Glaze every five minutes or so.
Brush the glaze on all sides of the meat during the last half hour of smoking. Make sure you cover all corners and crevices!
Repeat mopping every five or ten minutes or so in order to build up a nice and thick layer of shiny glaze.
You should be all done in an hour. The chicken is done when it reaches an internal temperature of 165 F / 73.8 C. Use an instant-read thermometer in the thickest part of the thigh.
