Say you were to combine two of the world's favorite drinks -- the Sazerac and the Old Fashioned. You'd get a drink very much like what you'll get from Bittermilk Mixer #4. Use with rye or bourbon, and this deeply flavored cocktail mixer will impart flavors of fennel, absinthe and bitter gentian root. After mixing, it's aged in Willet rye whiskey barrels for extra flavor. Made in South Carolina by Bittermilk.
