Grilled 10# of Angelo Caputo's most excellent sweet Italian sausage on medium heat (with sauteed sweet peppers, melted provolone and hot giardinara) for the team at work today. It was perfect, no bath necessary.
For brats, I prefer a post-grill bath in beer with onions and butter at home. Unfortunately, since I forbid beer at work in any form, I gently par-cook the brats in beer before grilling them at the office. That's the only time any sausage I grill gets close to boiling.
