So, where do those 97 calories come from, you ask? Well, it's quite simple really: 0 grams of fat, 0 grams of carbs, and a whopping 0 grams of protein - but a whole lot of alcohol. And let's be real, that's what we're really here for, right?
But seriously, the calories in Jack Daniel's (or any whiskey, for that matter) come from the ethanol - which is just a fancy word for alcohol. And at 35% ABV (alcohol by volume), Jack packs a pretty potent punch. So, be sure to pace yourself, or you might just find yourself singing "I'm a little tea pot" on top of the bar.
Now, I know what you're thinking: "What about the mixers?" Ah, my friends, that's where things can get really calorie-heavy. I mean, think about it: a Jack and Coke can range from 120-150 calories per serving, depending on the amount of Coca-Cola you add. And don't even get me started on the whiskey sour - that's just a calorie bomb waiting to happen.
