Both tequila and vodka, in their purest, unflavored forms, contain zero grams of sugar and zero carbohydrates. This reality often surprises people, as many assume the origin of the liquor (agave for tequila, grains or potatoes for vodka) dictates its final sugar content. The key to understanding this is the distillation process, which purifies the liquid and leaves the sugars behind, converting them to alcohol. A standard 1.5-ounce serving of 80-proof vodka and 100% agave tequila contains a similar amount of calories, with the energy coming solely from the alcohol itself, not sugar.
The Distillation Process: Separating Alcohol from Sugar
To produce spirits like tequila and vodka, raw materials rich in starches or sugars (agave, potatoes, or grain) are fermented. During fermentation, yeast consumes the sugars and converts them into ethanol and carbon dioxide. The resulting mixture is a low-alcohol liquid, often called a 'wash.' This liquid is then distilled, a process of heating and cooling that separates the alcohol from the water and other impurities. As the alcohol is separated and collected, the sugars and other solid matter from the original ingredient are left behind. This is why pure, unflavored distilled spirits are free of carbs and sugar.
Pure vs. Flavored Spirits and the 'Mixto' Factor
While unflavored spirits are a safe bet for zero sugar, the landscape changes significantly when you consider flavored varieties or certain types of tequila. This is where the confusion about sugar content often begins.
Flavored Spirits
- Flavored Vodkas: These are infused with flavors after distillation, and that process often involves adding sweeteners and sugar to achieve the desired taste. For instance, vanilla, caramel, or fruit-flavored vodkas may contain significant amounts of added sugar.
- Flavored Tequilas: Similarly, flavored tequilas or tequila liqueurs, such as coffee-flavored varieties, will contain added sugar and syrups.
Tequila's 'Mixto' Classification
Most quality tequila is labeled "100% agave," meaning it is made entirely from the blue agave plant. However, another category, known as "mixto" tequila, can be made with a minimum of 51% agave, with the rest coming from other added sugars. While distillation still removes sugars from the final product, the quality and taste profile differ, and it's best to stick to 100% agave for a purer product. It is crucial to check the label to ensure you're getting 100% agave if sugar content is a primary concern.
The Real Culprit: Mixers and Cocktails
For most people, the source of sugar in their drinks is not the hard liquor but the mixers used to create cocktails. A simple tequila sunrise or vodka tonic can quickly become a sugary indulgence. Some of the most common high-sugar mixers include:
- Regular soda and tonic water: A standard tonic water, for example, is loaded with sugar.
- Sugary fruit juices: Cranberry, orange, and pineapple juices can significantly increase a drink's sugar content.
- Pre-made margarita mixes: These are often packed with high-fructose corn syrup and other added sugars, transforming a low-sugar spirit into a high-sugar cocktail.
- Liqueurs and syrups: Sweeteners like triple sec, grenadine, and other syrups contain high sugar concentrations.
To keep your drinks low in sugar, opt for calorie-free mixers. Excellent choices include soda water, fresh lime or lemon juice, and a few drops of a natural zero-calorie sweetener if desired.
A Quick Comparison: Tequila vs. Vodka Nutrition
Here's a breakdown of the nutritional content for pure, unflavored 80-proof versions of each spirit, per a standard 1.5-ounce shot.
| Nutrient | 100% Agave Tequila | Unflavored Vodka |
|---|---|---|
| Sugar | 0g | 0g |
| Carbohydrates | 0g | 0g |
| Calories | ~97 kcal | ~97 kcal |
| Fat | 0g | 0g |
| Protein | 0g | 0g |
Conclusion
In conclusion, the belief that is tequila less sugar than vodka is a misconception. In their pure, unflavored forms, both spirits contain no sugar or carbohydrates, with their calories coming from the ethanol produced during fermentation and distillation. The real factor determining the sugar content of your drink is the mixers or flavored varieties you choose. For a low-sugar option, both tequila and vodka are equally suitable, provided you stick to the unflavored versions and mix them with sugar-free alternatives like soda water and fresh citrus juice. Remember that responsible and moderate consumption is key regardless of the sugar content.

The Impact of Congeners
One small difference between the spirits worth noting is the presence of congeners. These are minor compounds that give alcohol its distinct flavor and color. In general, darker spirits (like barrel-aged reposado or añejo tequila) tend to have more congeners than clear spirits like vodka, which can sometimes impact the severity of a hangover. This is a minor consideration compared to the sugar content of mixers, but it contributes to the overall profile of the drink.
Always Check the Label
For both tequila and vodka, the label is your best guide. To ensure your tequila is sugar-free, look for the "100% Agave" label. For vodka, assume that any flavored variety contains added sugar unless the label explicitly states otherwise. Checking these details can save you from an unexpected sugar spike and keep your drink aligned with your dietary preferences.
Alcohol and Overall Health
While pure spirits lack sugar and carbs, all alcohol should be consumed in moderation. Alcohol consumption can still affect blood sugar levels and has other health implications, regardless of the sugar content. What you mix it with can have a much larger impact on your overall health and wellness. By being mindful of your mixers, you can enjoy a lower-sugar cocktail without sacrificing flavor or enjoyment.
