Understanding the Distillation Process
Before diving into specific spirits, it's essential to understand why pure spirits contain no carbs. The journey begins with a carbohydrate source, such as grain (for whiskey and vodka), sugar cane (for rum), or agave (for tequila). This source is fermented by yeast, which consumes the sugars and produces alcohol. The crucial next step is distillation, a process that separates the alcohol from the fermented liquid, leaving behind virtually all the residual sugars and other carbohydrates. The result is a pure, distilled spirit composed primarily of ethanol and water, with a gloriously low-carb count of zero.
The Top Zero-Carb Spirits
For those on a keto or low-carb diet, the following spirits are excellent choices, provided they are consumed in their pure, unflavored form.
Vodka
Vodka is the quintessential low-carb choice. Made from fermenting carb-rich ingredients like potatoes or wheat, the distillation process removes all the carbohydrates. A 1.5-ounce shot of 80-proof vodka contains 0 grams of carbs and about 97 calories. It's a versatile, neutral spirit that pairs well with carb-free mixers.
Gin
Distilled from a neutral spirit and flavored with juniper berries and other botanicals, gin is another zero-carb option. Like vodka, its carb-free status depends on avoiding sugary additives. A standard 1.5-ounce serving of unflavored gin has 0 grams of carbs.
Tequila (100% Agave)
Authentic tequila made from 100% agave is naturally carb-free. Be cautious, however, as some cheaper "mixto" tequilas are mixed with other sugars that could increase the carb content. Always check for a 100% agave label. A 1.5-ounce shot of pure tequila contains 0 grams of carbohydrates.
Whiskey and Bourbon
Whiskey, and its American counterpart bourbon, are zero-carb spirits distilled from a grain mash. While the mash contains carbs, the distillation and aging process remove them. A standard 1.5-ounce serving of whiskey contains 0 grams of carbs.
Rum (Unflavored)
Unflavored rum, distilled from sugarcane byproducts, is another zero-carb contender. Flavored rums, however, can contain significant amounts of added sugar, so it's best to stick to the clear or golden varieties and avoid the spiced or sweetened options unless you've verified their nutritional content.
The Carb Culprits: Mixers and Flavored Spirits
While the spirits themselves may be carb-free, what you mix them with can quickly turn a low-carb drink into a sugar bomb. Fruit juices, regular sodas, tonic water, and pre-made cocktail mixes are packed with sugar and should be avoided.
Low-carb mixer options include:
- Club Soda or Seltzer: Adds fizziness with zero carbs and calories.
- Diet Tonic Water: A sugar-free alternative to regular tonic.
- Sugar-Free Sodas: Use diet versions of your favorite sodas.
- A Squeeze of Citrus: A wedge of lemon or lime adds flavor without carbs.
- Herbs and Bitters: Muddled mint, basil, or a few dashes of bitters can add complexity.
Comparison of Carb and Calorie Content
| Drink Type | Serving Size | Carb Content (grams) | Notes |
|---|---|---|---|
| Vodka, Gin, Tequila, Whiskey, Unflavored Rum | 1.5 oz | 0 | Pure distilled spirits, carb-free. |
| Dry White Wine | 5 oz | 3–4 | Lower-carb option; check for residual sugar. |
| Dry Red Wine | 5 oz | 3–5 | Moderate carb content; best in moderation. |
| Light Beer | 12 oz | 2–6 | Lower than regular beer, but not zero carbs. |
| Margarita | 4 oz | 19+ | Sugary mixers add significant carbs. |
| Regular Beer | 12 oz | 10–15 | Higher carb content due to malt sugars. |
Alcohol and Weight Management
It's important to note that while pure spirits have zero carbs, they are not zero-calorie. Alcohol contains roughly 7 calories per gram, which is nearly as calorically dense as fat. Additionally, alcohol consumption can impact your body's ability to burn fat. Your liver prioritizes metabolizing alcohol over other macronutrients, putting fat burning on hold. Alcohol can also increase appetite and lower inhibitions, leading to poor food choices. For this reason, moderation is key, even when choosing low-carb options.
Conclusion
When asking which spirit has less carbs, the clear answer is that pure, distilled spirits like vodka, gin, tequila, and whiskey contain zero carbs per serving. However, the true carb count of your drink depends entirely on what you mix with it. To keep your consumption low-carb, stick to straight spirits, mix with carb-free alternatives like club soda or diet tonic, and be wary of sugary mixers and flavored liquors. While a low-carb drink can fit into a mindful lifestyle, remember that alcohol consumption has other metabolic effects that can influence weight management, so moderation is always recommended.

The Low-Carb Spirit Challenge
For those looking to explore low-carb cocktails, consider the classic Vodka Soda with a lime wedge or a "Dirty Martini" made with gin and a splash of olive juice. Experimenting with fresh herbs like rosemary or basil in your cocktails can also add flavor complexity without the added sugars found in many liqueurs or syrups.
