Jack Daniel’s new Triple Mash Blended Straight Whiskey and Bonded Tennessee Whiskey represent the first two permanent expressions in the brand’s new Bonded Series. Jack Daniel’s Triple Mash is a blend of three straight bottled in bond whiskeys: 60% Jack Daniel’s Tennessee Rye, 20% Jack Daniel’s Tennessee Whiskey, and 20% Jack Daniel’s American Malt. According to the company’s press release, “Each expression is distilled in Lynchburg, Tennessee, in the same distilling season, aged to the stipulations of the Bottled in Bond Act, then blended and bottled at 100 proof. Jack Daniel’s American malt whiskey has been distilled by the company since 2013, is 100% malted barley, and in Triple Mash, meets the bottled in bond requirement making the malt at least 4 years old. This is the first release that the company’s malted barley whiskey is being used in."
