                                According to research published by MedlinePlus, a 1.5 fl oz shot of 80-proof whiskey contains about 97 calories. Since plain soda water is calorie-free, the number of calories in a whiskey soda is primarily determined by the whiskey itself, making it a relatively low-calorie drink option.
