I know you can get bacon flavored vodka by cooking the bacon over a cookie sheet, then pour the grease into Vodka. Let it marinate there for a few days or a week, then freeze the mixture. Bacon grease sits on top and vodka won't freeze. Decant vodka and re-freeze and decant until you're confident you got all the grease & bits out.
Don't ask me how this will taste in beer, but it makes a bitchin Bloody Mary!
