A standard 1.5 oz serving, or "shot," of Jack Daniel's Old No. 7 is a popular measure for its Tennessee whiskey. For those tracking their caloric intake, it's helpful to know the nutritional details. The good news for purists is that this classic spirit, when enjoyed neat or on the rocks, is free of carbohydrates, fat, and sugar. This makes it a relatively low-calorie choice compared to many other alcoholic beverages. The calories come exclusively from the alcohol itself, and understanding the proof is key to calculating the total.
The Calorie Breakdown of Jack Daniel's Old No. 7
For the flagship 80-proof (40% ABV) Jack Daniel's, a 1.5 oz pour contains about 97-98 calories. The calculation for a distilled spirit is straightforward: pure alcohol contains roughly 7 calories per gram. Since the spirit is calorie-dense, a small increase in alcohol content can lead to a noticeable bump in total calories. Importantly, because of the distillation process, all the sugar and carbohydrates from the fermented grains are left behind. This is why straight whiskies have a clean nutritional profile, but it also means the calories are considered "empty," providing energy without essential nutrients.
How Proof and Type Affect the Calorie Count
Not all Jack Daniel's products have the same number of calories. The proof, which is twice the percentage of alcohol by volume, is the primary factor. As the proof increases, so does the calorie count. Likewise, flavored versions introduce additional sugars and syrups that add significant calories.
Here is how calories vary across different Jack Daniel's products (per 1.5 oz serving):
- Jack Daniel's Old No. 7 (80 proof): 98 calories
- Gentleman Jack (80 proof): 98 calories
- Jack Daniel's Tennessee Honey (70 proof): 106 calories
- Jack Daniel's Single Barrel Select (94 proof): 114 calories
- Jack Daniel's Single Barrel Barrel Proof (up to 70% ABV): 153–172 calories
The Impact of Mixers on Your Calorie Intake
While straight Jack Daniel's is low in calories, its total can skyrocket when mixed with sugary sodas or juices. This is a crucial point for those managing their weight. A popular Jack & Coke is a prime example of how mixers add substantial empty calories.
Consider this simple comparison:
| Drink | Serving Size | Approximate Calories |
|---|---|---|
| Jack Daniel's (80 proof) neat | 1.5 oz | 98 |
| Jack & Diet Coke | 1.5 oz + 8 oz | ~100 |
| Jack & Regular Coke | 1.5 oz + 8 oz | ~190 |
| Whiskey Sour | 1.5 oz + mix | ~175 |
Choosing a diet or low-sugar mixer is an easy way to drastically reduce the total calorie load of a mixed drink.
Considerations for Weight Management
For those focused on weight loss, it’s not just about the calorie number; it's also about how the body processes alcohol. The liver prioritizes metabolizing alcohol over burning fat, which can hinder weight loss progress. Moderate intake is recommended, as excessive consumption has been linked to increased abdominal fat, particularly in women. Alcohol can also lower inhibitions and increase appetite, potentially leading to poor food choices.

Conclusion
A single 1.5-ounce serving of standard 80-proof Jack Daniel's contains just under 100 calories, specifically around 97-98. The calorie count is higher for elevated proof products and significantly greater when mixed with sugary sodas. For those monitoring their intake, enjoying the spirit neat or with a zero-calorie mixer is the best strategy. As with any alcoholic beverage, moderation is key for both calorie control and overall health.
