The Jack Daniel’s Twice Barreled American Single Malt Whiskey Finished in Oloroso Sherry Casks is the latest addition to the esteemed ‘Special Release’ limited edition collection of Jack Daniel’s. This unique whiskey, bottled at 108-proof, is perhaps the most distinctive whiskey ever produced by the Tennessee distiller. It is a truly innovative expression of whiskey-making that combines Jack Daniel’s iconic flavors with the characteristics of a single malt whiskey, predominantly made from malted-barley instead of corn or rye. The finishing touch of rich, sweet sherried cask influence adds depth and complexity to this whiskey, making it a must-have for collectors of Jack Daniel’s most special releases.
