Tin Cup Colorado American Whiskey is aged in new charred white oak American barrels and cut with rocky mountain water. It’s blended and bottled in Denver, Colorado. Legally speaking, it’s bourbon, but what makes Tin Cup unique is its high rye content which gives it a bold and spicy flavor. The cap screws on and can be used for drinking. The Mash Bill is 64% corn, 32% rye, & 4% malt. Tincup, CO is an old mining town in Gunnison County, set on the western side of the Colorado Rockies and named for the old cups the miners would drink from.
