Four Roses Single Barrel Kentucky Straight Bourbon Whiskey is made from a mash of 60% corn, 35% rye and 5% malted barley. Straight bourbon must be aged for a minimum of two years — Four Roses Bourbon is aged for a minimum of eight years in newly charred, white-oak casks.

The high rye content in the bourbon creates a rich, spicy flavor and gives the bourbon notes of nutmeg and cinnamon. A proprietary yeast culture used to ferment the mash produces a light, fruity balance to the spiciness and the aging process gives the bourbon notes of maple syrup and caramel.
