How Many Calories Are In Shot Of Tequila? | Bar Math

Calories In A Tequila Shot: What Changes The Number

Two variables set the count: how strong the spirit is and how much ends up in the glass. A neat pour has no carbs, fat, or protein; every calorie comes from ethanol at about 7 kcal per gram. In the United States, a standard pour for straight spirits is 1.5 ounces at 40% alcohol by volume (ABV), which contains about 14 grams of pure alcohol and lands near 98 calories (standard drink).

ABV, Proof, And Why It Matters

Proof is simply twice the ABV. So 40% ABV equals 80 proof. Higher proof means more alcohol per ounce and, by extension, more calories in the same pour. The Alcohol and Tobacco Tax and Trade Bureau defines proof as two times the alcohol by volume on U.S. labels, a convention you’ll see on bottles behind any bar.

Calories By ABV For A 1.5-Oz Pour

ABV (Proof)	Alcohol (g)	Calories
35% (70)	12.3 g	~86 kcal
38% (76)	13.3 g	~93 kcal
40% (80)	14.0 g	~98 kcal
43% (86)	15.0 g	~105 kcal
50% (100)	17.5 g	~123 kcal

Most straight pours of tequila fall between 38% and 40% ABV, right around the mid-90s in calories for a 1.5-ounce shot. If you’re pacing your day, it helps to look at the drink through the lens of daily calorie intake so the number fits your plan without guessing.

Shot Sizes And Pour Practice

Bars use jiggers, but free pours happen, and home glasses vary. That’s why calorie ranges can feel slippery. Here’s a plain-English view of common pours at 40% ABV and what they deliver.

One Ounce (The Small Nudge)

At 40% ABV, a 1-oz quick sip carries about 9.3 grams of alcohol and lands near 65 calories. It’s a modest option when you want the flavor without a full round.

One And A Half Ounces (Standard Bar Pour)

This is the standard serve across U.S. bars. At 40% ABV, you’re looking at ~14 grams of alcohol and roughly 98 calories. That’s the number most menus and nutrition calculators use.

Two Ounces (The Heavy Hand)

Now you’re near 17.5 grams of alcohol and ~131 calories. If the bartender pulls a generous free pour, this is where your glass often ends up, even when the menu says “single.”

Straight, Neat, Or On The Rocks

Neat or rocks adds no sugar and no extra energy beyond ethanol. The calorie math doesn’t change unless the spirit’s ABV changes. A blanco, reposado, or añejo at the same proof will sit at the same count per ounce.

When Mixers Enter The Glass

Calories climb fast when cordials, syrups, or sweet mixers join the party. Lime juice and soda water contribute very little, while triple sec, agave syrups, and premade sour blends can add triple-digit calories to a cocktail. That’s why a skinny margarita with fresh citrus and soda water sits closer to the base spirit’s count, while a frozen blend with liqueur and sugar races past it.

How The Math Works (So You Can Check Any Bottle)

You can estimate calories from any spirit once you know the pour size and ABV. All you need are three constants: 29.57 mL per fluid ounce, ethanol density of ~0.789 g/mL, and ~7 kcal per gram of alcohol. The steps below keep it simple.

Step-By-Step Shortcut

1. Convert the pour to milliliters: ounces × 29.57.
2. Multiply by ABV as a decimal to get mL of pure alcohol.
3. Multiply by 0.789 to convert mL of alcohol to grams.
4. Multiply by 7 to get calories.

Worked Example (1.5 Oz At 40% ABV)

1.5 × 29.57 = 44.36 mL of liquid. Alcohol present: 44.36 × 0.40 = 17.74 mL. Grams of alcohol: 17.74 × 0.789 ≈ 14.0 g. Calories: 14.0 × 7 ≈ 98 kcal. That lines up with the industry’s standard drink definition of about 14 grams of alcohol per straight pour and the CDC’s ~100-calorie note for a shot of distilled spirits.

ABV On The Label

U.S. labels print ABV and often proof. Proof is double the ABV. That means an 80-proof tequila is 40% alcohol by volume. If you pick a 70-proof bottle, your pour holds less alcohol per ounce and slightly fewer calories; a 100-proof pour goes the other way.

For label basics, the Alcohol and Tobacco Tax and Trade Bureau explains that proof is calculated by doubling the listed alcohol by volume on spirits labels (TTB proof definition).

Common Pours At 40% ABV

Pour Size	Alcohol (g)	Calories
1.0 oz	9.3 g	~65 kcal
1.25 oz	11.7 g	~82 kcal
1.5 oz (standard)	14.0 g	~98 kcal
1.75 oz	16.3 g	~114 kcal
2.0 oz	17.5 g	~131 kcal

Does Tequila Type Change The Count?

Blanco, reposado, and añejo all clock the same calories when the proof is the same. Aging changes flavor, not energy per ounce. Flavored products and tequila-based liqueurs are different. Some carry added sugars or lower ABV, which shifts both taste and math. If you see a bottle that reads below 40% ABV or includes sweeteners, expect the calorie total per shot to move.

Neat Versus Cocktails

A neat sip remains a pure ethanol calculation. Cocktails add wide-ranging extras. A no-sugar paloma with tequila, soda water, and lime stays close to the base spirit, while a creamy drink or frozen mixer can add hundreds of calories before the first toast.

Menu Moves That Keep Calories In Check

• Ask for a measured pour. Jiggers keep the serving at 1, 1.25, or 1.5 ounces.
• Choose lower-proof options when available. A 35% ABV pour trims grams of alcohol per ounce.
• Pick fresh citrus and soda water over syrups and liqueurs.
• Skip sugar-rim and heavy mixers; add a lime wedge for pop without energy creep.
• Nurse the glass. Ice and time let aromas bloom while intake stays steady.

How This Fits Into A Day

Calories from straight spirits are “empty,” meaning there’s no fiber, protein, or micronutrients riding along. One standard pour sits near a small snack in energy terms. If you’re tracking, log the number against your day’s plan and keep snacks, meals, and movement in view so the total still makes sense for your goals.

Quick Reference For Planning

• 1-oz neat, 40% ABV: ~65 kcal
• Standard 1.5-oz neat, 40% ABV: ~98 kcal
• 2-oz neat, 40% ABV: ~131 kcal
• Add mixers with sugar: expect a sharp rise

Why Sources Align Around ~100 Calories

Public-health materials often round a straight shot to ~100 calories. That aligns with the standard drink definition of ~14 grams of alcohol in a 1.5-ounce pour and the energy value of ~7 kcal per gram. The CDC’s data brief frames a 1.5-ounce liquor pour at about 100 calories, which matches the quick math above. NIAAA sets the standard drink baseline that drives the calculation across spirits, including tequila.

Bottom Line For Tequila Lovers

Calories swing with pour size and proof, not with color or aging style. Neat or on the rocks, the math stays clean. Add mixers and you change the picture. If you want a crisp, lower-calorie order, ask for a measured 1–1.5-ounce pour of an 80-proof bottle, squeeze citrus, and keep sugars out of the glass.

Sources And Method Notes

Energy values use the well-accepted 7 kcal per gram of alcohol and the U.S. standard drink baseline of about 14 g alcohol in a 1.5-oz pour. For definitions and public-health framing, see the National Institute on Alcohol Abuse and Alcoholism’s U.S. standard drink page and the CDC data brief that pegs a 1.5-oz liquor pour near 100 calories. For label terms, the TTB explains proof as double the ABV on spirits labels.
