Hey Mike, here is the recipe to make bacon infused bourbon. Other fat soluble flavors can be infused too using this technique (like peanut butter, other nuts). I saw one where a spoon full of peanut butter was added to the bacon fat before mixing.
I have tasted peanut butter bourbon.Kind of fun but I wasn't a big enough fan to buy a bottle. I have seen the bacon flavored stuff but never tried it. I should infuse some for Keith @66340SEDAN he is a big bacon fan.
