But, unlike whiskey, which is made with corn and rye, as well as malted barley, the only grain to be used in the single malt is malted barley. It's made with the same yeast used in its Tennessee whiskey and rye whiskey. The new Jack Daniel’s American Single Malt Whiskey ($99.99, 90 proof, available in select-duty free retail locations worldwide) is different from its Scottish relatives - there's no peat involved. There are few American single malts currently being made but those that are mostly come from craft distillers. When a spirits lover hears the phrase 'single malt,' they may think of single malt Scotch whiskys - often known for their grassy flavor because the malted barley may be dried with smoke from local peat moss.
After making whiskey for more than 150 years, Jack Daniel's has distilled something new: an American single malt whiskey.
