Old Elk Wheated Bourbon is a high-wheat bourbon from master distiller Greg Metze — built on a mash bill of 45% wheat, 51% corn, and 4% malted barley, and brought to proof slowly over weeks rather than days to preserve the spirit's delicate flavors.The unusually high 45% wheat content gives the bourbon a rich mouthfeel and lets the corn's natural sweetness and the barrel's light vanilla notes come through. Greg Metze brought four decades of distilling experience — including 14 years as master distiller at MGP — to Old Elk's production. The slow-cut proofing process adds fresh Colorado mountain water in small increments over weeks, keeping the spirit cool and avoiding the loss of lighter flavor compounds that rapid proofing can cause.Specs Producer: Old Elk Distillery, Fort Collins, Colorado Master Distiller: Greg Metze Style: Wheated Bourbon Whiskey Mash bill: 45% wheat, 51% corn, 4% malted barley Process: Slow-cut proofing over weeks Size: 750ml Browse all bourbon at Wooden Cork.
