REGION: Kentucky/United States NOTES: A rich flavor with a tinge of sweetness. Old Overholt is the oldest of The OldsTM, a relic you can drink. This famous Straight Rye Whiskey has a distinctive flavor and appeal that, after Prohibition, made it the most popular spirit in the country. Agreeable means you get along. And Old Overholt does just that. It’s renowned for its outstanding mixability in classic cocktails like the Old Style Manhattan (look it up). The one and only Old Overholt is 80 Proof and aged 3 years.
