Jack Daniel's Black Label Tennessee Whiskey has no carbohydrates (sugar or starch), gluten, fats, or cholesterol, as these are removed in the distilling process. One fluid ounce of Jack Daniel's contains approximately 65 calories.
Jack Daniel's, owned by Brown-Forman Corporation, is not a bourbon. It is dripped slowly - drop-by-drop - through ten feet of firmly packed charcoal (made from hard sugar maple) before going into new charred oak barrels for maturing. This special process gives Jack Daniel's Tennessee Whiskey its rare smoothness.
