How long to grill bratwurst depends on how you grill them. You can throw them straight on the grill which will take about 25-30 minutes or boil the brats in beer, wine or water for about 20 minutes. After boiling, then they are grilled for 4-6 minutes.
Prick bratwurst with fork to prevent them from exploding as they cook. Place in a large stock pot with the onions, butter, and beer. Place pot over medium heat, and simmer for 15 to 20 minutes. Preheat grill for medium-high heat. Lightly oil grate. Cook bratwurst on preheated grill for 10 to 14 minutes, turning occasionally to brown evenly.
