Process & Profile

Stranahan’s Diamond Peak Brewer’s Cask Batch 4 (2025) is a limited release small-batch American single malt distilled and aged in Denver (altitude ~5,280 ft) using locally sourced Colorado barley and Rocky Mountain spring water.

Each barrel is hand-selected and individually numbered, showcasing Stranahan’s commitment to innovation and terroir-driven character.
