Lowest calorie alcohol, by the published figures

October 16, 2026 · Viral Tandel

Lowest calorie alcohol is a question with a clear answer and a much more useful follow-up. The clear answer is that a neat spirit, at roughly 97 kcal for a standard 1.5 fl oz shot, is the lowest of anything the United States Department of Agriculture publishes a figure for. The useful follow-up is that almost nobody drinks spirits neat, and what goes in the glass afterwards usually matters more than what the spirit was.

Key takeaways

• All distilled spirits are 231 kcal per 100 g in USDA's data. Vodka, whiskey and tequila are identical.
• A 1.5 fl oz shot is about 97 kcal, using the 28 g per fl oz weight USDA publishes.
• Light beer is about 104 kcal per 12 fl oz bottle, regular beer about 155.
• Wine runs 135 to 153 kcal for the 180 g glass USDA weighs.
• The mixer decides the rest. Vodka and soda is about 133 kcal; vodka and cola is about 200.

By standard serving

Every figure is USDA FoodData Central, converted using the portion weight USDA publishes for that same entry: 180 g for a glass of wine, 360 g for a 12 fl oz beer, 225 g for a mixed drink, and 28 g per fl oz for spirits.

Three things fall out of that table immediately.

The spirit is not the variable. Vodka, whiskey and tequila are the same number. If a list tells you one spirit is meaningfully lighter than another at the same proof, it is not working from this data.

Tonic is not soda water. They sit next to each other at a bar and they are 56 kcal apart in the same drink, because tonic contains sugar and soda water does not. This is probably the single most common mistake in the whole category.

A cocktail is a different food. A whiskey sour is 277 kcal against 97 for the whiskey in it. You are drinking the syrup, not the spirit.

Why proof is the real driver

The calories in any alcoholic drink come from two places only: the alcohol itself, and any sugar that arrived with it. Spirits have essentially no sugar, which is why USDA lists vodka at 231 kcal per 100 g with 0 g of carbohydrate.

So for spirits, strength is the entire story. USDA's SR Legacy entries make it visible: vodka at 80 proof is 231 kcal per 100 g, while whiskey at 86 proof is 250. Same category, 7.5 percent more alcohol, 8 percent more calories. That is as close to a straight line as nutrition data gets.

The practical version: read the proof on the bottle rather than the name on it. A cask strength whiskey or an overproof rum is a materially bigger pour than the generic figures above, and nothing about the colour, the age or the price signals it.

Beer and wine behave differently, because both carry residual sugar as well as alcohol. Light beer at 29 kcal per 100 g against regular at 43 is a reduction in both at once, which is why the saving is proportionally larger than the drop in strength alone would produce.

Serving sizes are doing more work than they look

Every row in the table above uses a different serving size, because that is how these drinks are actually served. It is worth seeing the sizes plainly, since they explain most of the ranking.

A beer serving is more than eight times the weight of a shot. That a 12 fl oz light beer at 104 kcal lands anywhere near a 42 g shot at 97 kcal is the whole reason beer feels like a lighter drink than it is per unit of alcohol.

Put another way: these are not equal measures of alcohol. A standard US drink is defined to contain roughly the same alcohol in each of a 12 fl oz beer, a 5 fl oz wine and a 1.5 fl oz spirit, and on that basis the calorie figures above are reasonably comparable. Pour yourself a large glass of wine or a double spirit and the comparison breaks immediately.

What has no published figure here

Several popular categories are missing, and it is better to say so than to approximate them.

Hard seltzer. USDA publishes no entry this site holds. Most brands publish their own figures on the can, and those are the right source.

Cider. Same position. Cider varies enormously by sweetness and there is no generic figure here.

Craft beer. The generic beer entries cover regular, light and higher alcohol. A 7 percent IPA is not the generic regular beer entry, and USDA has no style-by-style breakdown.

Most cocktails. USDA covers a handful, including the whiskey sour and tequila sunrise above. A margarita, an old fashioned or an espresso martini has no entry here, and this site will not manufacture one.

For all of these, the brand's own published figures beat any database average, which is the reasoning behind the restaurant calculators on this site being built from brands' own data rather than estimated.

The honest limits of this table

USDA publishes a generic figure per category, not a figure for the bottle in your hand. Craft beer varies enormously by style and strength, and a 7 percent IPA is a different drink from the generic regular beer entry. Wines vary by residual sugar. Cocktails vary by whoever made them, and a bar measure is not a calibrated one.

So treat these as the right order of magnitude and the right ranking, not as a reading of your specific glass. Where a brand publishes its own figures, those are better, for the same reason set out in where calorie databases get their numbers.

Logging a night out

Log the drink, not the spirit. A vodka tonic is its own entry at 189 kcal, and logging it as a shot of vodka will understate it by half.

Count the drinks as you go rather than at the end. Alcohol is the category people most often reconstruct from memory the next morning, and reconstruction is where the undercount happens.

KalTrack can read a glass or a bottle label and give you the published figure rather than a guess. Point it at the bar.

This is general information about published nutrition data, not medical advice, and it is not advice to drink. If you are pregnant, taking medication, managing liver disease, or have any reason to avoid alcohol, those considerations sit entirely outside what a calorie figure can tell you. Speak to a clinician.
