Show Notes and Reviews

Colorado was long a bastion of the craft beer scene, and out of that grew a now-booming craft whiskey industry. Among the first of those whiskeymakers was Boulder Spirits (part of Vapor Distillery), who imported Alastair Brogan in 2012. His vision was clear: to create the best American single malt whiskey possible, while honoring traditional methods and embracing the distinctive Colorado environment. The Colorado microclimate plays a crucial role in Boulder Spirits' unique flavor profile. With significant temperature and humidity swings, whiskey ages differently here than in Scotland or Kentucky, experiencing higher evaporation rates that concentrate flavors more rapidly.

While their American Single Malt garners the headlines, they also make a fantastic bourbon, one that despite its relatively low proof (88) was full-bodied and flavorful. It confirmed my suspicions (piqued after chatting with Chattanooga) that I love malted bourbons, where malt is the secondary grain rather than rye or wheat. It holds up at a lower proof so much better than the other two.

Education remains the greatest barrier to growth - while we whiskey nerds love American Single Malts and different mashbills, the wider audience isn't always aware that ASM is even a thing, let alone a malted bourbon. That education is helped by collaborating with folks like Lost Lantern (that's how I first heard about Boulder) and putting out high-powered releases like hazmat single malt in armagnac casks.

I missed them by just a day while in Denver, but won't miss them the next time. Thank you to Alastair for entering the whiskey ring!
