The Old Fashioned is a timeless cocktail, a testament to the beauty of simplicity in the world of mixed drinks. Traditionally made with bourbon or rye whiskey, simple syrup, and bitters, it offers a delightful balance of spirit, sweetness, and spice. However, the classic recipe's sugar content poses a challenge for those adhering to a ketogenic or low-carb diet. Fortunately, with a few smart substitutions, it's entirely possible to enjoy a keto-friendly Old Fashioned that captures the essence of the original without derailing your dietary goals.
Understanding the Classic Old Fashioned
Before diving into the keto-friendly version, let's revisit the traditional Old Fashioned recipe. Typically, it consists of:
- 2 ounces of bourbon or rye whiskey
- 1/4 ounce of simple syrup (or a muddled sugar cube)
- 2-3 dashes of aromatic bitters (such as Angostura)
- Orange peel for garnish
The simple syrup, a mix of equal parts sugar and water, is the primary source of carbohydrates in this drink. To create a keto-compatible Old Fashioned, the key is to replace the simple syrup with a low-carb alternative.
The Keto-Friendly Simple Syrup Solution
The cornerstone of a keto Old Fashioned is a suitable sugar substitute. While several options exist, allulose powder stands out as an excellent choice. Erythritol, another popular sweetener, tends to form crystals when cooled, which can affect the texture of the syrup. Allulose, on the other hand, dissolves smoothly and doesn't recrystallize.
However, allulose is only about 70% as sweet as sugar, so a slightly adjusted ratio is needed. A good starting point is to combine 1.5 parts allulose powder with 1 part water. For example, you could use 1.5 cups of allulose powder for every 1 cup of water.

To prepare the keto simple syrup:
- Combine the allulose powder and water in a saucepan.
- Heat over medium heat, stirring constantly, until the allulose is completely dissolved.
- Remove from heat and let cool.
- Store in a closed container in the refrigerator for up to two weeks.
For an even more flavorful syrup, consider infusing it with spices like cinnamon or cloves during the heating process.
Crafting the Keto Old Fashioned
With your keto-friendly simple syrup in hand, you're ready to assemble your Old Fashioned. Here's a simple and delicious recipe:
Ingredients:
- 2 ounces of bourbon (choose a high-quality bourbon for the best flavor)
- ¼ ounce of keto simple syrup (adjust to taste)
- 2-3 dashes of orange bitters
- Ice
- Orange peel, for garnish
Instructions:
- In a rocks glass, combine the bourbon, keto simple syrup, and orange bitters.
- Add plenty of ice to the glass.
- Stir well until the drink is thoroughly chilled.
- Express the oils from an orange peel over the drink by gently squeezing the peel, then drop the peel into the glass as a garnish.
Selecting the Right Bourbon
Choosing a good bourbon is crucial for a truly enjoyable Old Fashioned. While personal preference plays a significant role, here are a few guidelines:
- Avoid flavored bourbons: Stick to traditional, unflavored varieties.
- Consider a higher-priced option: While budget-friendly bourbons have their place, investing in a slightly more expensive bottle can elevate the drink.
- Look for specific flavor profiles: Some bourbons offer notes of vanilla, caramel, or spice, which can complement the other ingredients in the Old Fashioned.
Bitters: A Key Ingredient
Bitters are essential for adding complexity and depth to an Old Fashioned. Orange bitters, in particular, provide a bright, citrusy counterpoint to the sweetness of the syrup and the richness of the bourbon. While Angostura bitters are more commonly used, you can use both types of bitters together or interchangeably.

Variations and Customizations
Once you've mastered the basic keto Old Fashioned, feel free to experiment with variations. Here are a few ideas:
- Spicy Old Fashioned: Muddle a slice or two of jalapeño with the keto simple syrup for a touch of heat.
- Smoked Old Fashioned: Use a smoked bourbon or add a few drops of liquid smoke to the drink.
- Citrus Twist: Experiment with different citrus peels, such as lemon or grapefruit, for garnish.
- Maple Old Fashioned: Use maple-flavored keto simple syrup.
Keto-Friendly Drink Mixers
Beyond the Old Fashioned, the world of keto-friendly cocktails has expanded significantly with the advent of low-carb mixers. Fever-Tree Refreshingly Light Tonic Water, for example, contains significantly fewer carbs than traditional tonic water. Fever-Tree Sparkling Pink Grapefruit is also a great option for keto-friendly Palomas.
For ginger-flavored drinks, Poppi Ginger Lime offers a lower-carb alternative to traditional ginger ale, while Zevia Ginger Ale provides a zero-carb option. Zevia also offers a range of other zero-carb sodas, including cola, cherry cola, root beer, and lemon-lime, which can be used to create a variety of low-carb cocktails.
Ready-to-Drink (RTD) Keto Cocktails
For those seeking convenience, several ready-to-drink keto cocktails are now available. Canteen Vodka Sodas and Cutwater Vodka Sodas are excellent zero-carb options. Cantina Tequila Sodas offer a tequila-based alternative, while Michelob Ultra and Smirnoff ICE also offer low-carb or zero-carb options. VIZZY hard seltzers, with their range of unique flavors, provide another option for those seeking a convenient and flavorful keto-friendly drink.

Drinks to Avoid (or Modify with Caution)
While many cocktails can be made keto-friendly, some are inherently high in carbs and should be approached with caution. These include drinks that contain:
- Liqueurs: Most liqueurs are heavily sweetened and contain a significant amount of sugar.
- Cream of coconut: A key ingredient in Piña Coladas, cream of coconut is very high in carbs.
- Traditional tonic water: Opt for diet or sugar-free tonic water instead.
A Note on Net Carbs
When calculating the carbohydrate content of your keto cocktails, remember to focus on net carbs. Net carbs are calculated by subtracting fiber and sugar alcohols from the total carbohydrate count, as these components generally have a minimal impact on blood sugar levels.
