Stranahans Diamond Peak Local Brewer’s Cask 750ML

Stranahan’s Diamond Peak Local Brewer’s Cask 750ML is a 90-proof (45% ABV) Colorado American single malt whiskey finished in local craft beer barrels. This limited expression earned an A- rating from Good Spirits News and stands as a distinctive collaboration between Colorado’s first legal distillery since Prohibition and some of the state’s most acclaimed breweries.Quick Facts: ABV: 45%  |  Origin: Colorado, USA  |  4–6 Year Base + 18-Month Beer Barrel Finish  |  Distillery: Stranahan’sProduction & HeritageStranahan’s holds the distinction of being Colorado’s first legal distillery since Prohibition and currently ranks as the nation’s top-selling American single malt whiskey. The Local Brewer’s Cask expression uses an innovative “boomerang” barrel technique: new American oak barrels that initially aged Stranahan’s 100% malted barley whiskey for four to six years were sent to partner Colorado breweries to hold bold craft beers—including Coffee Stouts, Barley Wines, and Belgian Quads. Those seasoned barrels then returned to the distillery, where they were filled with a blend of four- to six-year-old American single malt and finished for an additional 18 months. The final spirit is cut to proof with Rocky Mountain water and bottled non-chill filtered, preserving the full spectrum of flavor imparted by this dual-stage maturation.Tasting NotesAroma: Raisin and fig lead into chocolate-covered candied orange, with undercurrents of espresso and old cedar. As the whiskey opens, dried apricot and crème brûlée emerge alongside roasted malt and subtle coffee undertones.Taste: The entry delivers rich chocolate malt and a medley of dark berries, transitioning at mid-palate into semi-sweet chocolate chips and bright orange slices. Hazelnut and brown sugar sweetness round out the peak, balanced by a malt complexity that traces directly to the beer-barrel influence.Finish: Medium in length with a notably thick, mouth-coating texture. The close runs dry, leaving traces of roasted malt and dark chocolate lingering across the palate.How to Drink Diamond Peak Local Brewer’s CaskThe beer-barrel influence and non-chill filtered body make this whiskey particularly rewarding neat or with a few drops of water to open up the layered malt character. For cocktails, try an Old Fashioned, where the chocolate and berry notes add depth against bitters and sugar. A Boulevardier works well because the malty sweetness holds its own against Campari’s bitterness. A Whiskey Sour is another strong match—the fruity and nutty qualities complement fresh citrus beautifully.Best For
