In a small bowl combine chipotle pepper, cumin, salt, and pepper. Set aside.
Form beef into 4 8ounce patties, slightly larger than your bun. Make a slight indentation in the center of the burger to prevent it from doming up in the center. The indentation will rise as your burger cooks. Sprinkle burgers with seasoning mix. Gently press
Grill until golden brown and slightly charred (about 3 minutes), turning once (cook for 3 minutes on the other side for medium). Try not to press down on your burger with a spatula. It will cause the juices to escape and will create a dry burger!
Toast buns on low or indirect heat.
Pour 1/4 cup barbecue sauce on toasted bun. Place burger on top. Pour beer cheddar sauce over top and 4 slices of bacon.
