Understanding the Calories in Bourbon
Distilled spirits like bourbon get their calories almost exclusively from the alcohol (ethanol) itself. The distillation process removes carbohydrates, sugars, and other macronutrients from the fermented grain mash, leaving behind a liquid whose energy content is directly tied to its alcoholic strength. A single gram of pure alcohol contains approximately 7 calories, which is nearly as calorically dense as fat (9 calories per gram). This means that the primary factor determining how many calories are in 50 ml of bourbon is its proof.
The Impact of Proof on Calorie Count
Alcohol proof is a measure of the alcohol content in a beverage, with the proof number being twice the percentage of alcohol by volume (ABV). For example, a standard 80-proof bourbon is 40% ABV, while a 100-proof bourbon is 50% ABV. The higher the proof, the more alcohol is present in a given volume, and therefore, the higher the calorie count.
To calculate the calories in a 50ml serving, we can follow a simple formula. For an 80-proof (40% ABV) bourbon, a 50ml pour contains approximately 110 calories. For a higher-proof bourbon, such as 100-proof (50% ABV), the calorie count increases to roughly 138 calories per 50ml. This direct relationship is crucial for anyone monitoring their calorie intake.
Comparing Bourbon Calories by Proof
Different bourbons have different proofs, which directly affects their calorie count. Here is a simple comparison table illustrating how calories can change based on the bourbon's proof for a standard 50ml serving. These are estimates based on the general alcohol content.
| Bourbon Proof | Alcohol by Volume (ABV) | Approximate Calories (50ml) |
|---|---|---|
| 80 Proof | 40% | 110 calories |
| 90 Proof | 45% | 124 calories |
| 100 Proof | 50% | 138 calories |
| Cask Strength | 60%+ | 165+ calories |
The Hidden Calories: Mixers and Cocktails
While straight bourbon is free of carbs and sugar, the same cannot be said for many of the popular mixers used to create cocktails. Adding sugary sodas, juices, or syrups can dramatically increase the overall calorie count of your drink. A bourbon and cola, for example, can easily double or triple the number of calories. Similarly, classic bourbon cocktails, such as an Old Fashioned or Mint Julep, often include sugar, which adds to the total caloric intake.
To reduce the calories in a bourbon cocktail, consider these options:
- Use diet sodas: Opt for a diet cola or zero-sugar ginger ale to mix with your bourbon.
- Choose low-calorie mixers: Mix with plain soda water, a splash of water, or a few drops of bitters.
- Enjoy it neat or on the rocks: The lowest-calorie way to drink bourbon is to enjoy it on its own, without any additions.
- Infuse with natural flavors: For a low-sugar option, infuse your bourbon with natural flavors like cinnamon sticks or orange peels.
Bourbon vs. Other Spirits and Drinks
Compared to other alcoholic beverages, neat bourbon is a relatively low-calorie choice, especially when compared to beer or sugary cocktails. The absence of carbs and fat in straight bourbon makes it a popular option for those following low-carb or keto diets.
Here is a comparison of caloric content for 50ml servings (approximate):
- Bourbon (80 proof): 110 calories
- Vodka (80 proof): 110 calories
- Gin (80 proof): 110 calories
- Red Wine: Approximately 45 calories
- Lager Beer: Approximately 25 calories (per 50ml)
It's important to remember that these figures are based on the standard serving size and alcohol concentration. Drinking in moderation is key regardless of the beverage.
Tips for Mindful Bourbon Consumption
If you're keeping track of your calories, being mindful of your bourbon consumption is important. The calorie content is fixed per volume based on proof, but overall intake depends on how much you consume. Consider the following:
- Track your servings: Measure your pours to accurately track your caloric intake.
- Avoid over-pouring: Use a jigger or measuring tool instead of free-pouring to prevent an extra shot's worth of calories.
- Hydrate with water: Drinking water between alcoholic beverages can help you stay hydrated and slow down your consumption, reducing overall calorie intake.
The Final Pour: Summing Up the Calorie Count
The final takeaway is that the number of calories in 50ml of bourbon is directly tied to its proof. While a standard 80-proof bourbon will contain around 110 calories, a higher-proof version will have more. The beauty of bourbon, for those counting calories, is that it's a carb-free and sugar-free spirit. However, the mixers you add can drastically change the final calorie count. Enjoying bourbon neat or with low-calorie mixers is the best way to keep the caloric impact minimal.

Conclusion
In summary, a 50ml serving of bourbon contains a range of approximately 100 to 115 calories, with the exact figure dependent on the proof of the spirit. All calories are derived from the alcohol itself, making straight bourbon a carbohydrate-free and sugar-free option. For calorie-conscious individuals, it's vital to be aware that the addition of mixers and sweeteners can significantly increase the total caloric value. By understanding the relationship between proof and calories and making smart choices about mixers, you can enjoy bourbon responsibly while staying on track with your nutritional goals.
