Boulder Spirits, based in Boulder, Colorado, was founded by Scotsman Alastair Brogan with a passion for blending traditional Scottish distilling methods with Colorado's local resources. Known for producing high-quality American Single Malt Whiskeys, Bourbons, and other spirits, Boulder Spirits uses copper pot stills imported from Scotland, which bring a distinct, authentic character to their whiskeys.

They focus on crafting spirits with a unique Colorado twist, leveraging the region's high altitude and dry climate to influence the aging process.
