Stranahan's Diamond Peak 2025, the fourth batch of the Denver distillery's annual limited release, is the Local Brewer's Cask edition: a Colorado single malt aged six years in new charred American oak and then finished in barrels that held Colorado craft beers. It is bottled at 90 proof (45% ABV).
Stranahan's first ages its whiskey in new charred oak, then sends those barrels to local breweries to age bold specialty beers. For this release the barrels came back having held coffee stout, Belgian quadrupel and barleywine, and the single malt was finished in them to pick up roasted, fruity and malty layers.
Stranahan's helped found the American single malt category in Colorado, using Rocky Mountain water and 100% malted barley, and the brewery collaboration brings that story full circle.
Expect raisin, fig and chocolate-covered candied orange with espresso and old cedar, a whiskey for dessert and for beer lovers alike.
American whiskey covers a wide range of styles, from bourbon and rye to single malts and light whiskeys, and independent blenders and small producers have made it one of the most exciting categories in spirits.
