Mixologists and cocktail enthusiasts will enjoy adding this quality, all-natural mixer to aged spirits like bourbon or rye whiskey. Aged in Willett bourbon barrels to build intensity of flavor, it is highly concentrated—so a little goes a long way. Classic bittering agents like gentian root and cinchona bark combine with burnt sugar, spices and a bit of orange peel for a well-rounded result worthy of your best whiskey. Stir one part mixer and four parts spirit with ice, then garnish with an orange peel.

Bittermilk was founded by husband-and-wife team Joe and MariElena Raya to simplify the process of making craft cocktails at home. Their line of cocktail mixers is made with real ingredients, handcrafted and bottled in Charleston, South Carolina.
