291 Colorado Rye is the flagship product from Distillery 291 in Colorado Springs. This rye whiskey is a single barrel release distilled in a copper pot still, made from a mash bill showcasing malted rye and corn. After approximately one year maturation, it's then finished with charred aspen staves, the distillery's signature treatment. 291 Colorado Rye Single Barrel is bottled at 50.8% ABV.

Dark chocolate is showcased on the nose, with apricots, raspberries, and syrupy trail mix. The palate is rich, with chocolate and spearmint to the tune of thin mint cookies, as well as salted chocolate truffles, cedar box, and baking spices. The finish continues hitting on rich sweetness highlighted by dark chocolate.
