For the first time in its history, Jack Daniel’s will release a 100% malted barley grain bill, with the distillery’s new Jack Daniel’s Twice Barreled Special Release American Single Malt Finished in Oloroso Sherry Casks. This limited-edition Special Release expression is American Single Malt Whiskey twice barreled, and bottled straight from sherry casks at between 106.1 and 107.8 proof. Jack Daniel’s Twice Barreled Special Release American Single Malt begins with 100% malted barley that is ground, fermented and distilled in Lynchburg, TN. The whiskey passes through Jack Daniel’s traditional charcoal mellowing process, and then matures in new, charred American white oak barrels for at least four years. It then finishes for an additional two years in Spanish Oloroso sherry casks from the Antonio Paez Lobato Cooperage, before bottling at cask proof.
