Trail's End Kentucky Straight Bourbon Whiskey, distributed by Hood River Distillers, uses a mashbill of corn, malted barley and approximately 10% rye. Aged in new charred white oak barrels in Kentucky, it undergoes a finishing process in Oregon, where it is steeped with Oregon oak and blended with glacier-fed spring water from Mount Hood. Bottled at 90 proof, it is non-chill filtered.
