Old Elk Sour Mash Reserve is crafted with experience, passion and zero compromises. Our distillers took our award-winning flagship high-malt mash bill, and began the journey to discover what would change if we experimented with a different yeast. Our travels resulted in the unique Straight Bourbon Whiskey held in this bottle. The robust foundation that is our flagship high-malt mash bill anchors the heady complexities from the unique yeast. The result is a thirty barrel small batch whiskey that transports you. We hope you sip back, relax and enjoy.
