Some people play favorites...this one is ours. Fireside Single Barrel Bourbon begins with Colorado corn, spicy Colorado rye, chocolaty malted barley. We distill in a German-crafted copper still, then age a minimum of 4 years in new American Oak barrels in our Denver rack house. We then bottle at a precise 105.6 proof. Why? Because it's 52.80% ABV and we are Mile High Spirits!
