Evan Williams White label is our signature 100 proof, Bottled-in-Bond Bourbon. To be labeled as Bottled-in-Bond, a spirit must be the product of one distillation season and one distiller at one distillery, bottled at 100 proof and aged for at least four years under U.S. government supervision. Evan Williams White is bold and full-flavored, with all of the kick that you would expect from a 100 proof Bourbon without sacrificing any of the smoothness. Perfect in a classic cocktail, as well as neat or on the rocks.
