Shot of Whiskey Calories: Carbs, Sugar, and Full Nutrition Facts

You’re tracking what you drink and want to know what a shot of whiskey actually costs you calorically. A shot of whiskey calories comes entirely from alcohol, not from carbohydrates or fat, which makes whiskey one of the more diet-compatible spirits when consumed in moderation. Knowing how many calories in a glass of whiskey depends on pour size: a standard 1.5oz shot runs 97 to 105 calories, while a generous 2oz pour pushes that to 130 to 140 calories.

The good news for low-carb drinkers is that carbs in a shot of whiskey are essentially zero. Distilled spirits don’t retain the fermentable sugars from the grain, so carbs whiskey contains are negligible, usually less than 0.1g per serving. Calories in an ounce of whiskey run about 65 to 70 regardless of the type: bourbon, scotch, Irish, Japanese, or rye all land in the same range because calories from distilled spirits track directly with alcohol content.

Whiskey Calorie Count by Type and Pour

• 1.5oz shot (standard): 97 to 105 calories, 0g carbs, 0g fat, 0g protein
• 2oz pour: 130 to 140 calories, 0g carbs
• 3oz (double + extra): 195 to 210 calories, 0g carbs

Bourbon tends to run slightly higher in calories than scotch or Irish whiskey, but the difference per 1.5oz shot is 5 to 8 calories, not meaningful for tracking purposes. Cask-strength or barrel-proof whiskeys have higher alcohol content, often 60 to 65% ABV versus the standard 40%, which increases calories proportionally to around 140 to 160 per 1.5oz.

How Whiskey Calories Are Calculated

Alcohol contains 7 calories per gram, versus 4 per gram for carbohydrates and protein, and 9 per gram for fat. A 1.5oz shot of 80-proof (40% ABV) whiskey contains approximately 14 grams of pure alcohol. At 7 calories per gram, that’s 98 calories. The math is consistent across all 40% ABV distilled spirits: whiskey, vodka, rum, gin, and tequila all contain the same calories per 1.5oz standard pour at the same alcohol percentage.

What Mixers Add to Whiskey Calories

Whiskey on the rocks or neat adds zero mixer calories. Mixed drinks are where the calorie count climbs:

• Old Fashioned: 1.5oz whiskey + sugar cube + bitters. Adds 20 to 30 calories from sugar. Total: 120 to 135 calories.
• Whiskey sour: 1.5oz whiskey + 1oz lemon juice + 0.5oz simple syrup. Total: 180 to 220 calories depending on syrup amount.
• Jack and Coke: 1.5oz whiskey + 4oz regular cola. Cola adds 45 calories. Total: 145 to 155 calories.
• Jack and Diet Coke: 1.5oz whiskey + 4oz diet cola. 0 added calories. Total: 97 to 105 calories.
• Hot toddy: 1.5oz whiskey + honey + hot water + lemon. Honey adds 60 to 90 calories depending on amount. Total: 160 to 200 calories.

Whiskey vs. Other Alcoholic Drinks

Per standard serving, here’s how whiskey compares:

• Regular beer (12oz, 5% ABV): 150 to 180 calories, 10 to 15g carbs
• Light beer (12oz): 90 to 110 calories, 3 to 7g carbs
• Wine (5oz, 13% ABV): 120 to 130 calories, 3 to 5g carbs
• Margarita (4oz): 200 to 280 calories, 20 to 35g carbs
• Piña colada (6oz): 300 to 400 calories, 40 to 50g carbs
• Whiskey (1.5oz shot): 97 to 105 calories, 0g carbs

On a per-calorie basis, straight whiskey is the most efficient alcoholic drink. The problem is that most people don’t drink it in 1.5oz increments across the course of an evening.

Practical Tips for Drinking Whiskey While Tracking

• Drink it neat or on ice to eliminate mixer calories entirely.
• Use a measured jigger at home to know your actual pour size. A “heavy pour” at home often runs 2.5 to 3oz, which doubles the calorie estimate.
• Alternate each whiskey drink with a glass of water to slow consumption and reduce total intake.
• Log whiskey as “spirits, 80-proof” in tracking apps for the most accurate calorie count if the specific brand isn’t listed.

Bottom line: A shot of whiskey calories land at 97 to 105 per 1.5oz serving with zero carbs. It’s one of the lowest-calorie alcoholic options per serving. The carbs in whiskey are effectively zero because distillation removes all fermentable sugars. Manage pour size and mixers to keep the full drink within your calorie budget.
