This is my favorite way to cook beer brats. Whether you are having friends and family over to watch the game, tailgating at the stadium, or just in the mood for some good ol' fashioned comfort food that is easy to grill, this is a sure fire way to make perfect bratwurst on the grill. Here's the way I like to do it:

BRATS
1 stick butter
1 head of roasted garlic cloves
2 onions sliced 1/4" - 1/2" thick
1 24oz beer (lager)
6 -12 brats

Set up a grill for 2 zone cooking (indirect). Put butter in aluminum pan and warm. Dump in garlic. Once the butter is meted, add the onions. Add salt and black pepper.
Once the onions are soft and translucent, but not caramelized, add the beer.
Bring to a boil over direct heat then move to cold side of grill.
Add brats and cook 15-20 minutes covered in foil
Remove brats and move beer bath back to direct side of grill. Grill brats for 2-3 minutes/side until charred and whistling.
Add brats back in bath and serve. Further cook down onions if needed.
Keep covered and serve on a sausage roll with sauerkraut, and stone ground mustard. Add red pickled onions for extra flavor.

Enjoy!!!
