Heat up the bacon strips or pieces until it renders out the fat. Reserve infused bacon meat for food use.

Pour your bourbon and bacon fat into a container such as clean Tupperware and shaking gently to combine.

Allow the combined liquid to set for approximately an hour and then freeze overnight so the fat separates and hardens.

Once set scrape the fat off or use cheesecloth and strain the liquid to remove.

Most likely, a combination of both will be required; plan on having to strain the bourbon two or three times to thoroughly remove the unwanted solids.
