Plain vodka contains zero grams of sugar. A standard 1.5-ounce shot of 80-proof vodka has no sugar, no carbohydrates, and no fat. The calories in vodka (about 97 per shot) come entirely from the alcohol itself.
Why Vodka Has No Sugar
Vodka starts as a sugar-rich base, typically grain, potatoes, or fruit. During fermentation, yeast consumes all the natural sugars and converts them into alcohol. By the time fermentation is complete, no sugar remains in the liquid.
Distillation then takes the process a step further. The fermented liquid is heated until the alcohol evaporates, and that vapor is captured and condensed back into liquid. Sugar molecules don’t evaporate at the same temperature as alcohol, so they stay behind in the still. What comes out the other side is pure spirit, completely free of sugar.
A Small Legal Exception
There’s a catch most people don’t know about. U.S. regulations from the Alcohol and Tobacco Tax and Trade Bureau (TTB) allow vodka producers to add up to 2 grams of sugar per liter and up to 1 gram of citric acid per liter while still labeling the product simply as “vodka.” These tiny amounts can smooth out harshness or round out the mouthfeel, and many brands use this allowance.
At that maximum level, a 1.5-ounce shot would contain roughly 0.09 grams of sugar, a nutritionally insignificant amount. For comparison, a single grape has about half a gram. So even if your vodka does contain added sugar, the quantity is far too small to affect blood sugar, calorie counts, or taste in any meaningful way.
Why You Won’t Find It on the Label
If you’ve ever looked at a vodka bottle hoping to find a nutrition panel, you probably came up empty. TTB regulations do not require nutrition labeling on alcoholic beverages. Brands can voluntarily include calorie and carbohydrate information, but if they do, they must list calories, carbohydrates, protein, and fat per serving. Most producers skip it entirely rather than go through the extra compliance steps. The result is that consumers are left guessing, which is likely why you searched this question in the first place.
Flavored Vodka Is a Different Story
The zero-sugar rule applies to plain, unflavored vodka. Flavored vodkas fall into two very different categories, and the distinction matters.
Flavor-infused vodkas are made by steeping real fruit, herbs, or spices in the spirit during production. Many of these don’t contain significantly more sugar or calories than plain vodka, because the infusion adds flavor compounds without dumping in sweeteners.
Flavored vodka products that use syrups, sweeteners, or sugary flavorings after distillation are another matter entirely. These can carry substantial sugar. A premixed lemonade vodka cocktail, for instance, can contain around 25 grams of added sugar in a single serving, roughly six teaspoons. The label may say “vodka” in large print, but the sugar content looks more like a soft drink. If the bottle mentions a dessert-like flavor (whipped cream, caramel, marshmallow), it almost certainly contains added sweeteners.
Where the Sugar Really Hides: Mixers
For most people, the sugar in a vodka drink doesn’t come from the vodka. It comes from whatever you mix it with. A 2020 survey of pre-mixed alcoholic drinks found that the worst offenders packed more than 30 grams of sugar per serving, equivalent to about 8 teaspoons. Even a simple vodka with lemonade can contain 12 grams of sugar in a single can.
Here’s a quick comparison of common choices:
- Vodka and soda water: 0 grams of sugar. Soda water is just carbonated water, so it adds nothing.
- Vodka and diet tonic: 0 grams of sugar. Regular tonic water, on the other hand, is sweetened and can add 7 to 8 grams per serving.
- Vodka and cranberry juice: Typically 15 to 30 grams of sugar depending on how much juice is used and whether it’s a cocktail blend or pure juice.
- Vodka and ginger beer: Pre-mixed versions have been found with over 30 grams of sugar per serving.
If you’re trying to keep sugar low, vodka with soda water and a squeeze of fresh citrus is the simplest option. The vodka contributes zero sugar, and the mixer contributes close to zero. Swapping regular tonic for diet tonic alone can cut 7 or 8 grams of sugar from each drink.
