Whiskey is a distilled spirit made from fermented grain mash, and its fat content is essentially zero. But if you're tracking macros or building a diet plan, you might wonder exactly how much fat is in a 100-gram pour, and how that compares to other drinks. This calculator gives you the precise fat content per 100 grams of whiskey, along with the calories and carbohydrate breakdown, so you can log your intake with confidence.
Whether you're a fitness enthusiast, a nutrition student, or just someone who likes to know what's in their glass, this tool helps you convert your serving size into a standard 100g reference. You can also compare different whiskey types—bourbon, rye, scotch, and more—to see how they stack up nutritionally. Use the quick-fill buttons to load common serving sizes, then hit calculate to see your results instantly.
🥃 Whiskey Fat Per 100g Calculator
How to Use This Calculator
Enter the amount of whiskey you plan to drink, select the unit (grams, ounces, milliliters, or shots), and choose the whiskey type from the dropdown. The calculator converts your serving to a standard 100-gram reference and shows the fat content, along with optional calorie and carbohydrate estimates. Use the quick-fill buttons to load common serving sizes like a 1.5 oz shot or a 100 g pour.
If you're tracking macros, you can toggle the calorie and carb displays on or off. The result area shows the fat per 100g (which is always 0.00 g for pure whiskey), the total fat in your serving, and the estimated calories and carbs. This is especially useful when you're comparing whiskey to other alcoholic beverages or planning a low-fat diet.
Why Whiskey Has No Fat
Whiskey is a distilled spirit made from fermented grain mash (barley, corn, rye, or wheat). During distillation, the alcohol is separated from the solids and most of the congeners. The final product is essentially ethanol and water, with trace amounts of flavor compounds. Fats are large molecules that do not vaporize at the temperatures used in distillation, so they remain behind in the still. As a result, the fat content of whiskey is effectively zero—typically less than 0.1 g per 100 g, which is why nutrition labels list it as 0 g.
This is true for all types of whiskey, including bourbon, rye, scotch, and even cask-strength versions. The only exception would be flavored whiskey liqueurs that contain added cream or sugar, but those are not considered pure whiskey. If you're mixing whiskey with sugary sodas or cream, the fat and calorie content will increase significantly.
Calorie and Carb Estimates
While whiskey has no fat, it does contain calories from alcohol. Ethanol provides about 7 kcal per gram, which is nearly as energy-dense as fat (9 kcal/g). A standard 40% ABV whiskey has approximately 231 kcal per 100 g, while a higher-proof version (50% ABV) can reach 290 kcal per 100 g, and cask-strength (60% ABV) around 350 kcal per 100 g. These values are based on USDA FoodData Central and typical industry data.
Carbohydrates are also negligible in pure whiskey—usually less than 0.1 g per 100 g. However, if you drink whiskey on the rocks or with a mixer, the carbs from the mixer (like cola or juice) will add up. This calculator assumes you're drinking whiskey neat or with water, so the carb count stays minimal.
Worked Example
Example: You pour a 1.5 oz shot of standard whiskey (40% ABV).
1.5 oz × 28.3495 g/oz = 42.52 g of whiskey.
Fat per 100g = 0.00 g, so total fat = 0.00 g.
Calories = 231 kcal/100g × 42.52 g / 100 = 98.2 kcal (rounded to 98 kcal).
Carbs = 0.1 g/100g × 42.52 g / 100 = 0.04 g (negligible).
Common Mistakes to Avoid
- Confusing weight and volume: Whiskey is often measured in fluid ounces or milliliters, but nutrition facts are based on weight (grams). This calculator converts volume to weight using the density of whiskey (about 0.95 g/mL).
- Ignoring mixers: If you add cola, juice, or cream, the fat and calorie content will change dramatically. This tool only calculates the whiskey itself.
- Assuming all whiskeys are the same: Higher-proof whiskeys have more calories per gram because they contain more alcohol. Always check the ABV on the bottle.
Frequently Asked Questions
Does whiskey contain any fat at all? No, pure whiskey contains negligible fat—typically less than 0.1 g per 100 g. The distillation process removes virtually all fat.
Why does whiskey have calories if it has no carbs or fat? The calories come from alcohol itself. Ethanol provides about 7 kcal per gram, so a 1.5 oz shot of 40% ABV whiskey has roughly 98 kcal.
Is whiskey keto-friendly? Yes, because it has zero carbs and zero fat, whiskey fits into a ketogenic diet as long as you drink it neat or with a zero-carb mixer.
How does whiskey compare to beer or wine? Whiskey is more calorie-dense per 100 g than beer or wine, but you typically drink much smaller amounts. A standard shot has fewer calories than a pint of beer.
