If you’re a cocktail lover, chances are you’ve enjoyed the timeless charm of an Old Fashioned. This drink is simple, classy, and rich in flavor — but if you’re keeping an eye on your calorie intake, you might wonder: How many calories are in an Old Fashioned?
On average, a standard Old Fashioned contains about 150 calories, but this can vary depending on the ingredients and serving size. In this article, we’ll dive into the details, breaking down the calorie content, comparing it to other cocktails, and sharing tips for making a lighter version without losing that iconic taste.
What is an Old Fashioned?
The Old Fashioned is one of the oldest known cocktails, dating back to the early 1800s. Traditionally served in a short tumbler glass, it’s made with just a few ingredients:
- Whiskey – usually bourbon or rye
- Sugar – either a sugar cube or simple syrup
- Bitters – for a dash of aromatic flavor
- Garnish – typically an orange peel and sometimes a cocktail cherry
This simplicity is part of its appeal. Unlike many modern cocktails loaded with syrups and mixers, the Old Fashioned is straightforward — which also makes it easier to estimate the calorie count.

Calories in a Standard Old Fashioned
A typical Old Fashioned made with a standard recipe contains about 150 calories. Here’s a breakdown of where those calories come from:
Ingredient | Typical Amount | Calories |
---|---|---|
Whiskey (2 oz, 80-proof) | ~2 ounces | ~128 |
Sugar cube or 0.5 oz simple syrup | 1 cube or 0.5 oz | ~16 |
Bitters (2 dashes) | ~0.04 oz | ~1 |
Orange peel & cherry | Small amount | ~5 |
Total | – | ~150 |
Factors That Affect Calorie Count
While 150 calories is the average, your Old Fashioned could have more or fewer calories depending on:
- Type of Whiskey – Higher-proof whiskey has slightly more calories per ounce.
- Sugar Content – Using more syrup or a bigger sugar cube adds extra calories.
- Pour Size – A heavy-handed bartender can easily pour 3 oz instead of 2 oz.
- Extra Garnishes – A cherry in syrup adds extra sugar.
Old Fashioned vs. Other Cocktails
If you’re watching your calorie intake, it’s useful to see how an Old Fashioned compares to other popular drinks:
Cocktail | Average Calories |
---|---|
Old Fashioned | ~150 |
Margarita | ~200–250 |
Mojito | ~160–180 |
Martini | ~130 |
Manhattan | ~160 |
As you can see, the Old Fashioned is relatively moderate in calories, especially when compared to sweet, fruity cocktails.
Health & Nutrition Considerations
An Old Fashioned contains very little fat and protein, but it does have:
- Alcohol Calories – Alcohol has 7 calories per gram, making it calorie-dense.
- Sugar – While the sugar amount is lower than in most cocktails, it’s still worth noting for those on low-sugar diets.
- No Significant Vitamins or Minerals – The orange peel adds a touch of vitamin C, but not enough to be a meaningful source.
Alcohol can also slow metabolism, so moderation is key — not just for calories, but for overall health.

How to Make a Lower-Calorie Old Fashioned
If you love the flavor but want to cut back on calories, try these tips:
- Use less whiskey (1.5 oz instead of 2 oz).
- Swap the sugar cube for a few drops of liquid stevia.
- Skip the cherry garnish to avoid extra syrup calories.
- Choose a lower-proof bourbon to slightly reduce calorie density.
These changes can bring your Old Fashioned down to 100–120 calories without sacrificing much taste.
Frequently Asked Questions
