The 100 proof (50% ABV) Beam Suntory product is aged four years in accordance with the 1897 Bottled-in-Bond Act.
Old Overholt claims to be “one of the oldest whiskies out there,” and says it was one of the first to take advantage of the Bottled-in-Bond Act, passed in 1897. The law required all whiskies to be aged for four years, be bottled at 100 proof, and contain liquid from a single distillation season. Retail: $23.99.
