Boulder Spirits Colorado Straight Bourbon Single Cask

Real Mountain Bourbon

For our Summer of Bourbon products, we have created a Virtual Roadtrip with a stop for each distillery! Check out this product’s stop here.

Lost Lantern hand-selected this cask from Boulder Spirits in Colorado. The distillery was founded by Scotsman Alastair Brogan, who has brought Scottish whiskymaking traditions to the high peaks of the Colorado Rockies. This dry, high-elevation environment makes for bold and unique spirits.

This six-year-old straight bourbon whiskey was made from an unusual high-malt mashbill (51% corn, 44% malted barley, and 5% rye) that adds great heft and a hearty texture. It has a very rich nose, with notes of dark chocolate and warm apple strudel. It is warm, spicy, and sweet on the palate, with a very long finish.

An older and bolder follow-up to our first Boulder Spirits bourbon single cask, which scored 98 points in Wine Enthusiast–their top rated bourbon of 2022.
