Boulder Cask Strength Bourbon 2023

On deck for review today is Boulder Spirits’ 2023 limited release of their Cask Strength Bourbon. We’ve consistently been impressed with the high malted barley bourbon mashbill being distilled at Vapor Distillery in Boulder, so we have high hopes (and expectations) for this release. You should check out our podcast with Boulder Spirits in our archives; Bourbon Lens Episode 145: A Whiskey Adventure to the Mountains of Colorado with Boulder Spirits. So let’s dive into this proofy bourbon from the mountains of Colorado.

About Boulder Bourbon Cask Strength 2023:

  • Style: Colorado Straight Bourbon Whiskey
  • Mashbill: 51% Corn; 44% Malted Barley; 5% Rye
  • Proof: 135.2 (67.6% ABV)
  • Age: 6 Years
  • Batch Size: 13 Barrels
  • Price: $75.99
  • Availability: Limited, but available now on BoulderSpirits.com.

Scott’s Tasting Notes:

Nose: Malt, maple syrup, melted caramel, and brown sugar, with a hint of charred wood and grilled peaches.

Palate: anise, cinnamon, vanilla, buttery caramel, and baked fruits.

Finish: Lingering fruitiness and maple syrup in this lengthy finish.

Closing Thoughts

This bourbon delivers. While I’m far from a consistent cask strength bourbon drinker, this one packs a lot of flavor without the overwhelming proof burn that one might expect for a 135 proof whiskey. If you enjoy high malt content in your bourbon, or you are a single malt lover looking for a bourbon to test the waters, definitely check out Boulder’s lineup. And if you miss out on this limited release, you will be equally happy with their 100 proof Bottled-in-Bond offering as well.
