Yes, you can still enjoy cocktails on keto: choose pure spirits like vodka, gin, or tequila and combine them with low-carb mixers. A vodka soda, gin rickey, or glass of brut sparkling wine contains very few to no carbohydrates. However, be aware that alcohol temporarily halts your fat burning, so moderation remains the golden rule.
In short:
- Alcohol like vodka, gin, or tequila contains practically no carbohydrates, but mixers such as fruit juice or sweet syrup significantly increase the carb content.
- Drinking keto-friendly cocktails such as vodka soda, dry martini, or whiskey sour temporarily switches off fat burning, which is particularly disadvantageous with higher consumption.
- For example, a dry white wine of approximately 150 ml can still fit within a daily carbohydrate budget of 20 to 50 grams, provided you eat fewer carb-rich foods.
- Replacing sugary mixers with sparkling water, sugar-free syrups, and fresh citrus ensures your cocktail remains low-carb without sacrificing too much on taste.
- When socializing, it's important to set limits, eat fat-rich meals beforehand, and make smart choices, such as drinking water between alcoholic beverages.

What are keto cocktails and which recipes fit them?
Keto cocktails are drinks where you consciously choose spirits without added sugars and mixers that don't exhaust your carbohydrate budget. Most distilled spirits like vodka, gin, whiskey, rum, and tequila contain practically 0 grams of carbohydrates per standard serving. The problem almost always lies in the mixer: cola, fruit juice, or a sweet syrup can easily add 20 to 40 grams of carbohydrates per glass to a cocktail.
Below is a list of recipes you can make tonight, with a rough carbohydrate estimate per serving.
- Vodka soda: 5 cl vodka, sparkling water, a dash of lime. Approximately 0 to 1 g carbohydrates.
- Gin rickey: 5 cl gin, sparkling water, half a lime squeezed. Approximately 1 g carbohydrates.
- Ranch water: 5 cl tequila, sparkling water, a generous splash of lime juice, salt rim. Around 1 to 2 g carbohydrates.
- Dry martini: 6 cl gin or vodka, 1 cl dry vermouth, olive. Virtually 0 g carbohydrates.
- Skinny margarita: 5 cl tequila, fresh lime, a dash of sugar-free agave syrup alternative or monk fruit syrup. Approximately 2 to 3 g carbohydrates.
- Keto paloma: 5 cl tequila, sparkling water with a splash of grapefruit juice (small!), lime, salt rim. Approximately 3 to 4 g carbohydrates.
- Keto mojito: 5 cl white rum, fresh mint, lime, sparkling water, a few drops of liquid stevia. Around 2 g carbohydrates.
- Keto mule: 5 cl vodka, sugar-free ginger beer, lime. Approximately 1 to 2 g carbohydrates, provided the ginger beer is genuinely sugar-free.
- Prosecco spritz (brut): 10 cl dry brut sparkling wine, sparkling water, lemon peel. Approximately 2 to 3 g carbohydrates.
- Sugar-free whiskey sour: 5 cl whiskey, fresh lime, small splash of monk fruit syrup, egg white optional for foam. Approximately 2 g carbohydrates.
- Alcohol-free mocktail with sparkling water and bitters: sparkling water, a few drops of aromatic bitters, fresh mint and lime. Virtually 0 g carbohydrates and completely alcohol-free.
A dry white wine of about 150 ml usually contains 2 to 3 grams of carbohydrates, which often fits within a daily budget of 20 to 50 grams. Play with fresh herbs such as mint, rosemary, or basil and a small dash of bitters: this adds depth of flavor without adding carbohydrates.

Please note: beer is often excluded from this list. A lager already provides 8 to 13 grams of carbohydrates per glass, craft beer can go up to 25 grams, and even alcohol-free beer surprisingly often contains 10 to 14 grams. For keto, beer is usually not a good choice.
How to make regular cocktails low-carb?
The trick is that you rarely need to change what's in the glass, only what you mix with it. Soft drinks, fruit juice, and classic syrups like grenadine or amaretto are full of sugar and will quickly push you out of ketosis. Replace them systematically:
- Swap soft drinks for sparkling water. You get the same bubbly feeling without a gram of sugar.
- Check the label of light tonic. Not every "sugar-free" tonic truly is. Some still contain several grams of carbohydrates per 100 ml.
- Use syrup based on erythritol or monk fruit instead of classic sugar syrup. You can boil this yourself with water and sweetener or buy it ready-made.
- Work with fresh citrus in small quantities. Half a lime adds few carbohydrates and gives a lot of flavor.
- Build a simple home bar: a shaker, measuring cups, a sharp knife for zest, fresh herbs, and a bottle of sugar-free syrup are enough to make ten recipes.
For more explanation about which mixers you should avoid, and what role syrups play in the taste of your cocktail, a good substitute is often just as important as the spirit itself.
Pro-tip: On the weekend, make a bottle of homemade syrup with erythritol, water, and a flavoring such as ginger or raspberry. This way, you always have a sugar-free base ready during the week, without having to mix it anew every time.
What does alcohol do to your ketosis and what should you watch out for?
Your liver treats alcohol as a poison that needs to be cleared first. As long as that task is ongoing, your fat burning stops. That's the core of the problem: not the spirit itself, but the fact that your body always prioritizes alcohol over fat burning.
Alcohol temporarily pauses your fat burning, and many people on keto notice they get drunk faster and experience a heavier hangover than before. The reason is often not in the spirit itself, but in the mixers that secretly add sugar.
This faster intoxication is not imaginary. Due to the low glycogen stores, your body has less buffer, causing alcohol to hit harder. For people using medication for diabetes or blood pressure, this combination can also cause your blood sugar to fluctuate unpredictably, so discuss this with your doctor beforehand.
A few rules keep this manageable. Drink water between each glass of alcohol, which helps against dehydration and the next morning. Before bed, take extra salt or a sugar-free electrolyte drink, as alcohol expels electrolytes from your body faster than usual. Always eat something high in fat beforehand. And if you measure ketones, only do so the next morning: immediately after drinking, it gives a distorted picture.
How to socialize without derailing your keto goals?
A night out doesn't have to ruin your progress if you plan ahead. It's about three simple decisions you make at home, before the first glass is in front of you.
- Set a limit of one to two drinks and drink a glass of water between each. This prevents you from unconsciously continuing and helps against dehydration.
- Eat a high-fat and protein-rich meal beforehand, and keep a keto snack on hand for on the go, such as some nuts or cheese.
- Estimate your macros roughly before ordering: a spirit with sparkling water is almost free, a cocktail with juice or syrup can easily eat up your entire evening budget. If you feel dizzy or lightheaded, drink water immediately and eat something, as this often indicates low blood sugar combined with alcohol.
If you're unsure between drinks, always choose the driest option on the menu. That principle alone prevents most mistakes.
Ready-to-drink keto cocktails: when to order them instead
Mixing yourself is fun, but not every evening you have time to make syrups, calculate ratios, or buy five bottles of spirits for one party. Cocktailsbynina delivers bar-quality cocktails that are ready to serve, made with premium ingredients, so you don't have to bother with sugar-free syrups and measuring cups yourself.
For those who watch their carbohydrates, the range of alcohol-free cocktails and ready-to-drink mocktails is an easy alternative if you prefer to drink no alcohol at all but don't want to stand with just water in your hand. If you're planning a party or birthday, a cocktail box with 4 pieces is just enough for a small gathering, without you having to shake or measure yourself. If you're still in doubt, order a cocktail box with 2 pieces first to taste which flavors suit your keto evening.
The personal side of keto and cocktails
What always strikes me: people on keto often skip cocktails entirely, fearing that one drink will ruin their entire week. This is unjustified. A vodka soda or dry martini costs you almost nothing in carbohydrates, as long as you keep an eye on the mixer.
The real pitfall is not the alcohol itself, but the social moment around it: chips, a cocktail with juice in it, and another round because everyone else is continuing. Plan ahead, choose dry, and truly enjoy what you drink instead of gulping it down quickly.
