A 1.5-oz shot of Hennessy at 40% ABV has about 98 calories; smaller or larger pours change the number.

Calories In Hennessy By Pour Size (Chart)
Cognac sits in the distilled-spirit family at 40% ABV for core labels. That means calories come almost entirely from ethanol. Ethanol provides ~7 calories per gram, and a 1.5-oz pour of 40% ABV lands close to 98 calories when you run the math from grams of alcohol to energy. The CDC defines a “standard drink” as 1.5 ounces of 80-proof liquor (40% ABV), which matches how most bars measure a shot.
| Pour Size | Alcohol (g) | Calories (kcal) |
|---|---|---|
| 1.0 oz (30 ml) | ~9.3 g | ~65 |
| 1.25 oz (37 ml) | ~11.7 g | ~82 |
| 1.5 oz (44 ml) | ~14.0 g | ~98 |
| 2.0 oz (59 ml) | ~18.6 g | ~131 |
| 3.0 oz (89 ml) | ~28.0 g | ~196 |
| 5.0 oz (148 ml) | ~46.7 g | ~327 |
Those figures use the standard formula for spirits: volume (ml) × ABV × 0.789 g/ml = grams of alcohol; grams × 7 = calories. A 40% ABV shot aligns with the CDC’s reference pour for liquor. For planning a night out, it helps to anchor around your daily calorie needs so these numbers fit your day without guesswork.
What Drives The Number
ABV is the lever. Raise the alcohol by volume and calories climb even if the glass size stays the same. Most classic bottles in the range (V.S, V.S.O.P, X.O) are bottled at 40% ABV in many markets. Limited releases or special cask finishes can differ by region, but 40% is the baseline most drinkers see on the shelf.
Why Spirits Bring Calories Without Carbs
When a brandy is distilled to bottling strength and served neat, calories come from ethanol, not sugar. Public health sources peg ethanol at ~7 calories per gram, and U.S. regulators explain that most straight distilled spirits don’t carry carbohydrates, protein, or fat. That’s why a neat pour tracks like the chart above; mixers change the picture.
Standard Drink And Bar Pours
A U.S. “standard drink” equals 14 grams of pure alcohol. In the spirits category, that’s a 1.5-oz shot at 40% ABV. Many bars pour exactly that for a single, while a double is commonly 2 ounces. If you’re logging intake, align your tracker with the CDC’s standard sizes for a cleaner comparison to any recommendations you follow.
How Mixers And Cocktails Change Calories
A neat pour sticks near the values above. Mixers add energy fast. Cola, ginger ale, sweet liqueurs, syrups, or juice can stack 80–200 calories on top of the spirit. A long soda-water highball barely moves the needle, but a sweet tea or cola build can more than double a single shot’s calories.
Simple Swaps That Save Calories
- Pick soda water, diet soda, or unsweetened tea instead of full-sugar mixers.
- Use citrus peel or a squeeze of lemon for aroma without added sugar.
- Measure the base pour; most creep comes from heavy hands, not just the mixer.
ABV Matters: Same Glass, Different Calories
Some special-edition cognacs and cask-strength bottlings can run hotter than 40% ABV. Here’s how one 1.5-oz pour changes with different strengths.
| ABV | Alcohol (g) | Calories (kcal) |
|---|---|---|
| 35% | ~12.3 g | ~86 |
| 40% | ~14.0 g | ~98 |
| 43% | ~15.1 g | ~105 |
| 45% | ~15.8 g | ~110 |
| 50% | ~17.5 g | ~123 |
How Those Numbers Are Calculated
The math is consistent across straight spirits. Multiply the liquid volume in milliliters by ABV, then by ethanol’s density (0.789 g/ml) to get grams of alcohol. Multiply grams by 7 to get calories. That 7-kcal factor is the accepted energy value for ethanol in nutrition and public health resources.
Carbs, Sugar, And Labels
Neat distilled spirits are essentially free of carbs and fat; calories are driven by ethanol itself. U.S. regulators don’t require a Nutrition Facts panel on liquor, and brands can optionally share a Serving Facts panel with calories and macros per serving. If you’re scanning a bottle and don’t see a label, that’s normal in this category.
Practical Serving Tips
Choose The Pour
Stick to a single 1–1.5-oz pour if you’re aiming for a modest bump in energy intake. A measured jigger or a home mini-measure helps a lot.
Pick Mixers Wisely
Soda water with citrus keeps the character of the spirit while keeping your glass near the neat-pour calorie range. If you enjoy cola or ginger beer builds, consider smaller glassware or extra ice to cut mixer volume.
Plan The Day Around Your Glass
Calories from alcohol offer energy but few nutrients. Aim to place your pour alongside a balanced meal and steady hydration. That simple habit tends to reduce refills and keeps the overall day in a good place.

Reference Notes
Standard Drink
The CDC defines a standard drink as 14 grams of pure alcohol and lists a 1.5-oz shot of 80-proof liquor (40% ABV) as one standard unit. That’s the baseline used for the charted values above and matches how most bars measure a single.
Energy From Ethanol
Public health agencies and government resources treat ethanol at about 7 calories per gram. That’s why pour size and ABV are the two dials that move totals the most.
Why You Rarely See A Nutrition Label
In the U.S., the Alcohol and Tobacco Tax and Trade Bureau (TTB) regulates labels on spirits. A Nutrition Facts panel isn’t mandatory. Brands may include calorie and macro statements if they follow TTB rules on how to present that information.
For serving sizes and baselines, see the CDC’s page on standard drink sizes. For a quick way to estimate weekly totals, NIAAA’s calorie calculator shows how recurring pours add up. TTB also explains why spirits don’t always carry a nutrition panel and when calorie statements are allowed.
