                                A standard 30 mL serving of Jack Daniel's Tennessee Whiskey (Black Label, 40% ABV) contains approximately 65 to 66 calories. This means a single shot is a relatively low-calorie option, as all calories come exclusively from the alcohol content itself, with no carbs or sugar.
