The Blanton's brand was introduced in 1984 under the direction of the distillery's master distiller, Elmer T. Lee, as the first modern bourbon brand to be marketed as a single barrel bourbon. "Blanton's Single Barrel Bourbon" was the brand's original name. A single barrel bourbon is bourbon in which the contents of only one specific maturation cask are used to make each batch for bottling and are not combined with whiskey from other casks (and are not mixed with neutral spirits, coloring, or flavoring). The company claims that using this production method requires regular monitoring of each cask at the center of the warehouse by the Master Distiller in order to produce a high quality whiskey. The barrels are emptied manually without the use of machines.
