How Many Calories Are in Alcohol? A Plain Reference

About 153 calories in a 12-ounce regular beer, about 125 to 130 in a 5-ounce glass of wine, and about 97 in a 1.5-ounce shot of 80-proof spirits: those are the useful baseline figures from MedlinePlus.

The numbers are approximate. Brand, pour size, alcohol content, sugar, and mixers can move them up fast.

The quick reference table

Drink	Typical serving	Approximate calories
Light beer	12 fl oz	103
Regular beer	12 fl oz	153
Higher-alcohol or craft beer	12 fl oz	170 to 350
Table wine	5 fl oz	about 125 to 130
80-proof spirits	1.5 fl oz	97
94-proof spirits	1.5 fl oz	116

MedlinePlus lists these beverage-calorie ranges as reference values for common alcoholic drinks. A sweet cocktail, liqueur, frozen drink, or large pour can land well above the clean table number.

Set the denominator: one standard drink

Calories and alcohol amount are not the same measurement. Calories describe energy. A standard drink describes pure alcohol.

NIAAA defines a U.S. standard drink as 0.6 fluid ounces, or 14 grams, of pure alcohol. A 12-ounce regular beer, a 5-ounce glass of wine, and a 1.5-ounce shot of 80-proof spirits each contain about one standard drink.

That is why the calorie numbers can look uneven even when the alcohol amount is similar. A shot of 80-proof spirits has about one standard drink and about 97 calories before mixers. A regular beer has about one standard drink and about 153 calories. The beer includes more volume and other ingredients.

For the alcohol-unit side of this, see what counts as one standard drink. For wine math, see how many drinks are in a bottle of wine.

What changes the number

Alcohol content is one driver. Higher-alcohol beer has more calories than many lower-alcohol beers. Higher-proof spirits contain more alcohol per ounce, and MedlinePlus lists 94-proof spirits at about 116 calories per 1.5-ounce serving compared with 97 calories for 80-proof spirits.

Serving size is another driver. A 5-ounce wine number does not describe a large home pour. A 12-ounce beer number does not describe a 16-ounce draft. A 1.5-ounce spirits number does not include a double.

Sugar and mixers are the third driver. Juice, soda, syrups, cream, sweet liqueurs, and frozen-drink bases add calories that are not in the spirits number. A pour of vodka and a sweet mixed drink built on vodka are not the same calorie reference.

The practical mistake is comparing categories as if they stay fixed. "Wine is lower than beer" can be true for one serving and false for another pour. "Liquor is lower" can be true before the mixer and false after the cocktail is built. The reference number only works when the serving size is the reference serving.

Use the table as a starting point, then adjust for what is actually in the glass.

Why people call them "empty calories"

NIAAA's Rethinking Drinking calculator frames alcoholic beverages as supplying calories but few nutrients, and it lets people estimate weekly calories from beer, wine, and spirits.

"Empty" does not mean the calories are fake. It means the drink adds energy without much nutritional value. For people who are cutting back, that can be a useful piece of awareness, not a moral judgment about body size or food.

This is also where calories can become the wrong question. The page can help count drinks. It should not turn into a diet plan, a fasting plan, or a promise that cutting back changes weight by a certain date.

For the body-change question, read alcohol and weight changes. For appetite after drinking, see does alcohol make you hungry.

Weekly totals add up quickly

Five regular beers in a week are about 765 calories using the 153-calorie reference. Five 5-ounce glasses of wine are roughly 625 to 650 calories. Five 1.5-ounce servings of 80-proof spirits are about 485 calories before mixers.

Those are arithmetic examples, not advice. They show why a "small" number of drinks can still be visible over a week, especially if the drinks are larger, stronger, or sweetened.

The cleanest use of the numbers is tracking. Count the drink type, the serving size, and the approximate calories. If the question is weight, health, or nutrition, bring the pattern to a clinician or registered dietitian rather than making an internet plan.

A non-shaming way to use the numbers

The numbers are most helpful when they lower confusion. They are least helpful when they become a body-shame tool.

For one week, a factual note can be enough:

• drink type
• serving size
• number of servings
• whether it was mixed or sweetened
• approximate calories from the table

That note will not tell anyone what their body should do. It will show whether alcohol calories are a meaningful part of the week. For many people trying to cut back, that clarity is the point: fewer guesses, fewer vague "not that much" stories, and a cleaner picture of where one small change would matter.

FAQ

Is liquor lower in calories than beer or wine?

Plain 80-proof spirits are lower per standard serving than many beers and wines, but mixers can change the total quickly. The standard spirits number is not the same as a cocktail number.

Are alcohol calories always "empty calories"?

NIAAA uses that framing because alcoholic beverages supply calories but few nutrients. It is a nutrition description, not a character judgment.

Will cutting back make me lose weight?

This page cannot promise body changes. Cutting back can reduce alcohol calories, but weight is affected by food, sleep, movement, health conditions, medications, and many other factors.
