Blanton’s Single Barrel is released once a year from single-batch barrels, with each batch having its own unique flavor that exists once and never again. Blanton’s also releases other editions such as Straight From the Barrel (an unfiltered, uncut bottle) and Gold, each of which is also only released once per year. Because bourbons are usually produced by taking different barrels of whiskey and blending them together, Blanton’s single-barrel bourbons are exceedingly rare.
