Evan Williams Single Barrel is the only vintage dated single barrel Bourbon on the market. Similar to the way vintage wines are selected, our distillers hand-select individual barrels that meet the specifications they've established. Then each bottle is marked with the vintage date it was put into oak, along with the year it was bottled and the exact barrel number of the single barrel that the Bourbon was drawn from. Available at the Evan Williams Bourbon Experience and select Kentucky retailers.
