Old Hamer Single Barrel BourbonAge: 4 years Proof: 100 proof Batch: OH WFB1 About the product: In the 19th century, some called it the nest whiskey around. We still call it that. For years, the Hamer Family operated a mill in Lawrence County, IN, distilling excess corn and selling it to whiskey lovers as far south as New Orleans. Once lost in the sands of time, Old Hamer is ready to enjoy again resurrected by West Fork Whiskey.
