Benchmark Kentucky Straight Bourbon Whiskey, 1.75l Plastic Bottle 80 ProofIn 1773, three McAfee Brothers left Virginia westward to explore the uncharted territory that would later become known as Kentucky. The brothers surveyed the land now home to the world's most award winning distillery Buffalo Trace Distillery. The surveyor marks left behind are known as benchmarks and this bourbon whiskey honors the pioneering spirits of these early American explorers.
