Cocktail clarification involves mixing all ingredients - spirits, citrus, fruits, bitters, sugars, etc. - with milk, resulting in a transformed drink by removing suspended particles. This method produces crystal-clear cocktails with unexpectedly smooth, silky, creamy textures.

While bovine milk is traditionally used for clarification due to its unique curdling properties, plant-based milks don't curdle the same way. To address this, we freeze the cocktail, allowing plant-based milk to curdle effectively.

In our Clarified Koatji Old Fashioned, we elevate the classic flavors with an umami boost from our star ingredient, Koji, and create a silky, smooth version of this beloved cocktail.
