Preheat an outdoor grill to medium heat, about 375-400 degrees F.
Dump or drink 1/3 of the bee,r leaving 2/3 of the beer remaining in the can. Add 2 garlic cloves to the beer.
In a small bowl mix together salt, pepper, Italian seasoning and garlic powder.
Pat the chicken dry and place it on top of the beer can by inserting it into the chickens cavity so that the bird is sitting upright.
Rub the entire bird with olive oil, then rub with dry seasoning mixture.
Place lemon wedge inside the top of the chicken sticking out slightly.
Place bird right side up on the grill NOT in direct flames. Cook for 1.5 hours or until thermometer inserted into the thigh reads 165 degrees F. (*I like to rotate the chicken around halfway through the cooking time).
Remove from grill and let sit for 10 minutes before removing beer can and carving.
The type of beer doesn't really matter here as it doesn't add flavor.
