Description

This is a 4-year-old Straight Bourbon Whiskey from Boulder Spirits in Colorado, bottled in bond at 50% ABV (100 proof). It is distilled by Vapor Distillery in Boulder, Colorado. The bourbon is aged in new charred American white oak barrels. It features a non-traditional mash bill of 51% corn, 44% malted barley, and 5% rye, resulting in a malt-forward and less sweet character. The whiskey is known for its rich and developed profile.
