Understanding Alcohol's Impact: Does Tequila Have Protein?

October 17, 2025 •

3 min read

Across the board, nutritional data confirms that a standard 1.5-ounce serving of 80-proof tequila contains 0 grams of protein, 0 grams of fat, and 0 grams of carbohydrates. This is because the distillation process effectively removes all macronutrients from the fermented agave mash, leaving behind only alcohol and water. If you're wondering, does tequila have protein?, the simple answer is no.

Quick Summary

Tequila contains zero protein, carbohydrates, or fat, with all calories stemming from the alcohol itself, which contains 7 calories per gram. The distillation process strips away nutrients, resulting in 'empty calories'. Knowing its true nutritional profile is key for a balanced diet and weight management.

Key Points

No Protein, Carbs, or Fat: A standard 1.5-ounce shot of 80-proof tequila contains 0 grams of protein, carbohydrates, and fat.
Calories from Alcohol: All calories in pure tequila come from the alcohol itself, which provides approximately 7 calories per gram.
Empty Calories: Since it lacks nutrients, the calories in tequila are considered 'empty' and provide energy without nutritional benefit.
Distillation is Key: The manufacturing process, particularly distillation, is what removes the proteins and other macronutrients from the fermented agave.
Watch the Mixers: The caloric and sugar content of cocktails can vary dramatically based on the mixers used, so plain tequila is a much lower-calorie option than a margarita.
100% Agave is Best: For minimal additives and sugars, choose tequilas explicitly labeled as '100% agave'.
Similar to Other Spirits: The calorie count for pure tequila is comparable to other distilled spirits like vodka and whiskey on an ounce-for-ounce basis.

The Tequila Production Process and Nutritional Profile

Tequila is a distilled spirit made from the fermented sugars of the blue Weber agave plant. The journey from plant to bottle explains why the finished product contains no protein. The agave plant's core, or piña, is cooked to convert complex carbohydrates into simple, fermentable sugars. This sweet liquid, called aguamiel, is then fermented with yeast to produce a low-alcohol liquid known as mosto. The final and most crucial step is distillation, where the liquid is heated and separated into its components. This process is highly effective at purifying the spirit, removing the fermented agave fiber, and stripping away all macronutrients like proteins, fats, and carbohydrates, leaving behind a liquid that is primarily alcohol and water.

A Closer Look at Tequila's Nutrient Composition

For those watching their dietary intake, understanding what is and isn't in their glass is crucial. Tequila offers a straightforward nutritional profile, but it is not without its calorie implications. The calories in a shot of tequila come exclusively from the alcohol content.

The Source of Tequila's Calories

While devoid of protein, fat, and carbs, tequila is not calorie-free. Alcohol itself is a source of energy, providing approximately 7 calories per gram, which is more than carbohydrates or protein (4 calories per gram) but less than fat (9 calories per gram). This is why the calories in distilled spirits are often referred to as 'empty calories'—they provide energy without offering any meaningful nutritional value such as vitamins, minerals, or macronutrients.

Tequila Nutrition at a Glance

Protein	0 grams	0 grams
Carbohydrates	0 grams	0 grams
Fat	0 grams	0 grams
Calories	~97 calories	~224 calories

Navigating Tequila Within a Healthy Diet

While pure tequila itself has a simple nutritional composition, the way it is consumed plays a massive role in its overall dietary impact. For those on low-carb or keto diets, tequila is often a preferred choice because it contains no carbohydrates. However, the inclusion of sugary mixers in popular cocktails like margaritas can drastically change this, adding hundreds of calories and grams of sugar. Opting for pure 100% agave tequila over mixtos is also recommended, as mixtos are allowed to contain up to 49% non-agave sugars, which can mean more additives and sugar.

The Role of Mixers

When considering tequila in a diet, it's essential to account for all ingredients in the final drink. A simple tequila with sparkling water and a squeeze of lime will remain a low-calorie option, whereas a margarita can be packed with calories from syrup and juice. For a more balanced approach, consider the following options:

Skinny Margaritas: Use fresh lime juice and a natural, low-calorie sweetener instead of pre-made mixes.
Tequila Soda: Mix tequila with club soda and a citrus wedge for a refreshing, low-calorie drink.
Sipping Neat: Enjoying a high-quality reposado or añejo neat allows for appreciation of the agave flavor without any added sugars.

Tequila vs. Other Spirits

Comparing tequila to other liquors reveals that its calorie count per serving is quite similar to other 80-proof spirits, with the main nutritional differences arising from how they are produced and the types of mixers used.


Spirit (1.5 fl oz, 80-proof)	Calories	Carbs	Sugars	Protein
Tequila	~97	0g	0g	0g
Vodka	~97	0g	0g	0g
Whiskey	~97	0g	0g	0g
Rum	~97	0g	0g	0g
Red Wine (5oz)	~125	Varies	Varies	Trace

It is worth noting that while calorie counts for pure spirits are similar, the congeners (impurities) present in some darker, aged liquors may contribute to a worse hangover compared to clear spirits like tequila. However, the alcohol itself is the primary factor, and moderation is key regardless of the beverage.

Conclusion

To answer the question, does tequila have protein?, the answer is a resounding no. As a distilled spirit, tequila contains no protein, carbohydrates, or fat. All of its calories come from the alcohol itself, which the body processes differently than other nutrients. While tequila can be part of a balanced diet, particularly for those monitoring carb intake, it is crucial to remember that its calories are 'empty' and offer no nutritional benefit. Paying attention to mixers and consuming in moderation are the most important factors for managing its impact on overall nutrition and wellness.

Frequently Asked Questions

A standard 1.5-ounce (45 ml) shot of 80-proof tequila contains approximately 97 calories. This can vary slightly depending on the brand and proof.

While tequila has similar calories to other distilled spirits, its reputation as 'healthy' is often tied to its low sugar content in its purest form and the fact that 100% agave tequilas lack additives. However, the alcohol itself remains a source of empty calories.

Tequila is produced through distillation, a process that separates the alcohol from the fermented agave mash. This purification removes the original plant's macronutrients, resulting in a finished product with zero protein, carbs, or fat.

Yes, mixing tequila can significantly alter its nutritional profile. Combining tequila with sugary juices, syrups, or sodas adds carbohydrates, sugar, and calories that are not present in the pure spirit.

Yes, pure tequila is a zero-carb alcoholic beverage, making it suitable for keto and low-carb diets. However, it is essential to stick to pure tequila without sugary mixers and to account for the calories from the alcohol.

100% agave tequila is made exclusively from the blue Weber agave and is less likely to contain added sugars or artificial flavors. Mixto tequila can be made with up to 49% non-agave sugars, which can increase the sugar and calorie content.

While some studies have explored potential health benefits linked to compounds in agave, most are removed during distillation. Any perceived health benefits are heavily debated and do not outweigh the negative impacts of excessive alcohol consumption. As with all alcohol, moderation is key.
