How to Fat Wash Bourbon: A Step-by-Step Guide

Have you ever heard of fat washing bourbon? It may sound strange, but this process can add a unique flavor and texture to your favorite whiskey. In this article, we’ll explain what fat washing is, how to do it, and answer some common questions about the process.

What is Fat Washing?

Fat washing is a technique that involves infusing a spirit with the flavor of fatty ingredients such as bacon, butter, or coconut oil. The fat is melted and mixed with the alcohol, then left to sit for a period of time to allow the flavors to meld. After the fat has solidified, it is removed, leaving behind a spirit with a distinct flavor and texture.

Why Fat Wash Bourbon?

Fat washing can add a unique and delicious flavor to your bourbon. It can also add a creamy, silky texture that is not typically found in whiskey. Additionally, fat washing is a fun and creative way to experiment with different flavors and ingredients.

How to Fat Wash Bourbon

To fat wash bourbon, you will need:

  • 1 bottle of bourbon
  • 1 cup of melted fat (bacon grease, butter, coconut oil, etc.)
  • A large glass jar with a lid
  • Cheesecloth or a fine mesh strainer

Here’s how to do it:

  1. Melt your chosen fat in a pan over low heat until it is completely liquid.
  2. Pour the melted fat into the glass jar.
  3. Add the bottle of bourbon to the jar and stir gently to combine.
  4. Put the lid on the jar and shake it vigorously for several minutes to ensure the ingredients are well mixed.
  5. Store the jar in a cool, dark place for at least 24 hours. The longer you leave it, the stronger the flavor will be.
  6. After 24 hours, place the jar in the freezer for a few hours until the fat has solidified.
  7. Once the fat has solidified, use a spoon to scrape it off the top of the bourbon.
  8. Strain the bourbon through cheesecloth or a fine mesh strainer to remove any remaining bits of fat.
  9. Pour the bourbon back into its original bottle or into a clean glass jar.
  10. Your fat washed bourbon is now ready to enjoy!
