Buffalo Trace Distillery in Frankfort, Kentucky, makes some fine whiskey, but none is treasured drop-by-drop like Blanton's Bourbon.Why metal and not brick? The metal heats and cools quicker, allowing faster aging. Hot days and cool nights cause the whiskey barrels to expand and contract, creating a deep and complex product. While most of the barrels at Buffalo Trace are moved and poured by machine, those destined for a Blanton's label are strictly manipulated by hand. Single barrel spirits come from (you guessed it) only one barrel, the best in the barn and often in the center. It is not diluted nor are any colors or flavors added. The flavor is big and unique. The proof varies from batch to batch. Blanton's Bourbon is typically around 93-proof.
