For anyone following a ketogenic diet, finding delicious, low-carb alcoholic drinks can be a challenge. The key to a great keto cocktail lies in understanding which ingredients are carb-free and which are loaded with hidden sugars. With a few simple substitutions, you can transform popular high-carb cocktails into keto-friendly versions without sacrificing flavor.
The Foundation: Zero-Carb Spirits
Starting with a clean, unflavored base spirit is the first step to creating a successful keto cocktail. Many hard liquors are naturally carb-free because the distillation process removes fermentable sugars.
- Vodka: A versatile, neutral spirit that works in countless low-carb combinations. Flavored vodkas, however, should be avoided as they often contain added sugar.
- Gin: Made from juniper berries and other botanicals, dry gin is another excellent zero-carb choice. It pairs wonderfully with sugar-free tonic or soda water.
- Tequila: Stick to 100% agave tequila for a carb-free base for your margaritas and palomas.
- Whiskey & Bourbon: These spirits are also carb-free, though some flavored varieties may contain sugar. An Old Fashioned can be made keto-friendly by replacing the sugar with a low-carb sweetener.
- Rum: Use white, unflavored rum for mojitos and other classic rum drinks. Dark and spiced rums should be checked for added sugars.
Perfecting Your Mixers and Sweeteners
The mixer is where most standard cocktails rack up their carb counts. Switching to sugar-free alternatives is crucial for a keto-friendly drink.
Low-Carb Mixer Options
- Club Soda / Sparkling Water: A perfect zero-carb mixer for highballs like a vodka soda or a gin rickey.
- Diet Soda: Use diet versions of classic sodas like diet cola, diet ginger ale, or diet lemon-lime soda to replace their sugary counterparts.
- Diet Tonic Water: Regular tonic is loaded with sugar, so always opt for a diet or sugar-free version for a keto gin and tonic.
- Unsweetened Juices & Extracts: A small amount of fresh lime or lemon juice adds flavor without many carbs. Use extracts like orange extract to mimic the flavor of high-sugar liqueurs.
Keto Sweetener Alternatives
Many classic cocktails rely on simple syrup for sweetness. The good news is you can make a zero-carb simple syrup at home.
- Monk Fruit & Erythritol: These powdered or liquid sweeteners can be dissolved in water to create a keto simple syrup.
- Liquid Stevia: A few drops of liquid stevia can be used to sweeten drinks directly.

What to look for:
- 0g or 1-2g carbs: Always check the nutrition facts for the carbohydrate count.
- Natural Sweeteners: Look for products sweetened with stevia, monk fruit, or erythritol instead of artificial sweeteners that can cause a chemical aftertaste.
- Clean Ingredients: The best options use minimal, recognizable ingredients. NÜTRL Vodka Sodas, for example, are known for having 0g carbs and 0g sugar.
Tips for Enjoying Keto Cocktails Responsibly
Alcohol consumption can impact ketosis, so moderation is key. Here are some tips for enjoying a keto cocktail without derailing your progress:
- Stay Hydrated: Drink plenty of water alongside your cocktails to combat dehydration, which can be exacerbated by alcohol on a ketogenic diet.
- Mind Your Tolerance: Your alcohol tolerance may be lower on keto. Start slow and see how your body reacts before having another drink.
- Time Your Drinks: Consider having your cocktail alongside a low-carb meal or snack to minimize the metabolic impact.
- Choose Wisely at the Bar: If you're out, stick to simple orders like a vodka soda with a lime twist, as many bar mixers are sugar-laden. When in doubt, ask.
