Why Distilled Spirits Have Zero Carbs
The zero-carb status of reposado tequila is a direct result of its production process. Tequila starts with the piñas, or hearts, of the blue agave plant. These are cooked to convert starches into fermentable sugars, which are then extracted. Yeast is added to ferment these sugars into alcohol. Finally, the liquid is distilled, which is the key step in removing carbohydrates. Distillation heats the fermented liquid, turning the alcohol into vapor while leaving behind non-alcoholic components like sugars and carbohydrates. The vapor is then collected and condensed back into a liquid, resulting in a high-proof, pure spirit that is naturally carb-free.
For reposado, this distilled spirit is then aged in oak barrels for a period of two to twelve months. While this aging process imparts the tequila's characteristic golden color, smooth flavor, and notes of vanilla and oak, it does not reintroduce carbohydrates or sugars into the final product. The pure spirit remains carb-free throughout.
The Difference Between Tequila Types and Carbohydrate Content
For those on a low-carb or ketogenic diet, it's important to understand that the distillation process applies to all high-quality tequilas, regardless of their aging period. This means that blanco (un-aged), reposado (aged), añejo (extra-aged), and extra añejo (ultra-aged) varieties all contain zero carbs, as long as they are 100% agave.
The key distinction to be mindful of is between 100% agave tequila and a mixto tequila. Mixtos are legally allowed to contain up to 49% non-agave sugars, which can introduce carbohydrates into the final product. However, if you stick to brands labeled "100% Agave," you can be certain you're drinking a carb-free spirit.
Comparison of Carb Content in Popular Alcoholic Beverages
To put reposado's zero-carb nature into perspective, let's compare it to other common alcoholic beverages. This highlights why spirits are often the preferred choice for those managing their carb intake.
| Beverage Type | Serving Size | Approximate Carb Content (grams) | Notes | 
|---|---|---|---|
| Reposado Tequila | 1.5 oz shot | 0g | All 100% agave tequila is carb-free. | 
| Light Beer | 12 oz can | 2–6g | Lower carb than regular beer, but not zero. | 
| Regular Beer | 12 oz can | 10–15g | Contains carbs from fermented grains. | 
| Dry Wine | 5 oz glass | 3–5g | Contains residual sugar from grapes. | 
| Margarita | 8 oz serving | 20–30g | Carbs come from sugary pre-mixes or sweeteners. | 
| Whiskey | 1.5 oz shot | 0g | Distilled spirit, no carbs. | 
How Mixers Add Carbs to Tequila Drinks
While the tequila itself is carb-free, the majority of popular tequila cocktails can be loaded with sugar. A standard frozen margarita, for example, can have a staggering 36 grams of carbs per serving due to sweet mixes and syrups. For those on a low-carb diet, the secret is to be selective with what you mix with your reposado. Some excellent low-carb and keto-friendly options include:
- Club Soda or Seltzer: A simple and refreshing mixer that adds zero calories and zero carbs. A reposado and soda with a squeeze of fresh lime is a perfect low-carb option.
- Fresh Lime Juice: A small amount of fresh lime juice adds flavor without a significant carb count. Avoid bottled lime juice, which often contains added sugars.
- Sugar-Free Sweeteners: For a sweeter taste, you can use a few drops of a sugar-free alternative like stevia or monk fruit. Always check the ingredients for hidden carbs.
- Diet Tonic Water: Tonic water typically contains sugar, but diet versions are a zero-carb alternative.
Enjoying Reposado on a Keto or Low-Carb Diet
For those following a ketogenic or low-carb lifestyle, reposado tequila can be a great choice when consumed correctly. A standard shot, or a drink made with zero-carb mixers, will not disrupt ketosis. However, it's crucial to account for the calories from the alcohol itself, which is metabolized by the body differently than carbs or fat. The body will prioritize metabolizing the alcohol, which can temporarily pause fat burning.
The Calories in Reposado
Despite having zero carbs, reposado still contains calories. A standard 1.5-ounce shot of 80-proof tequila has about 97 calories, with all of those calories coming from the alcohol content. Each gram of alcohol contains roughly 7 calories, so a standard shot contains about 14 grams of alcohol. This means you should enjoy reposado in moderation, as excessive alcohol consumption, regardless of carb content, can contribute to weight gain.
Practical Low-Carb Cocktail Recipes
For a delicious, guilt-free drink, consider these simple recipes:
- Keto Tequila & Soda: 1.5 oz reposado tequila, 4 oz club soda, fresh lime wedge. Serve over ice in a tall glass.
- Low-Carb Paloma: 1.5 oz reposado tequila, 4 oz diet grapefruit soda, fresh lime juice. Serve over ice with a lime wedge garnish.
- Reposado on the Rocks: For a smoother, purer taste, simply serve reposado over ice with a twist of orange peel to bring out the oaky notes.
Conclusion
In summary, reposado tequila is a naturally zero-carbohydrate spirit, a fact that holds true for all 100% agave tequilas due to the distillation process. The aging in oak barrels adds flavor complexity but does not add any sugar or carbs. The key to keeping your tequila drinks carb-free is to avoid high-sugar mixers like syrups, fruit juices, and pre-made margarita mixes. By choosing low-carb or zero-carb mixers, you can enjoy the rich flavors of reposado without compromising your dietary goals. Just remember that the calories still count, so moderation is always recommended.
