Benjamin Rosen of Onyx & Amber on Making Unconventional Whiskey in Colorado

by | Sep 27, 2025

Randy Warren talks with Benjamin Rosen of Onyx & Amber about breaking whiskey’s quiet rules. Discover why Onyx & Amber is not a distillery, but sources barrels from MGP Distillery and others, then transforms them through Colorado’s extreme barometric pressure swings. Learn why he prices 18-year whiskey at a fair $74.99, avoids “middle flavors,” and runs his five-person operation from Boulder warehouses. Ben also explains how high-altitude aging creates unique flavor profiles without actually speeding up time.
