Whisky Jack Daniels. Jack Daniels is produced in the same traditional way that its creator first defined 142 years ago. The materials used are exclusively from the land of Tennessee, cereals and crystal clear groundwater. Unlike bourbon whiskies, Tennessee whisky goes through an additional process before being closed in a barrel for maturation. After distillation, Jack Daniels matures in the cellars in new white oak barrels, made in the distillery barrel. During its maturation, it absorbs various ingredients from the wood of the barrel, which give it its characteristic taste and its deep red hue. Jack Daniels stands out for its unique, balanced taste, with elements of smoked wood, caramel and vanilla, while its rich, deep amber color indicates its unique taste characteristics and its soft fruity aroma.
