Understanding the Agave Foundation
Both mezcal and tequila are distilled spirits made from the agave plant, a succulent native to Mexico. The core differences that affect their health profiles stem from the specific agave species used and the variations in their respective production processes. Tequila, for instance, is legally limited to only one type of agave, the Blue Weber agave (Agave tequilana), and must be produced in specific Mexican states, primarily Jalisco. In contrast, mezcal can be made from over 30 different types of agave, leading to a wider range of flavors and potential trace compounds.
The Impact of Production Methods
Perhaps the most significant health differentiator lies in how the agave is cooked. Tequila production often involves cooking the agave piñas in industrial steam ovens or autoclaves, a more efficient but less rustic approach. Mezcal, however, is traditionally made by roasting the agave hearts in underground, cone-shaped pits lined with volcanic rock. This earthy roasting process is what imparts mezcal's signature smoky flavor and can influence its final chemical makeup.
Tequila's use of additives: A major distinction is the allowance for additives. By Mexican law, some tequilas, specifically those not labeled as "100% agave," can contain up to 49% of their sugars from other sources, such as cane sugar or corn syrup. These non-agave sugars can contribute to more severe hangovers and negate potential health benefits associated with pure agave. Quality mezcal, on the other hand, is legally required to be 100% agave, ensuring a purer spirit with no added sugars or artificial flavors.
Calorie, Sugar, and Carb Content
When considering spirits like mezcal and tequila, it’s a common misconception that they are loaded with calories and sugar. In reality, a standard 1.5-ounce serving of either pure mezcal or 100% agave tequila contains around 97-98 calories, with zero carbohydrates and zero sugar. The calorie count is similar for both when comparing like-for-like quality. The issue arises when consumers opt for cheaper, mixto tequilas with additives or when mixers like soda, juice, or margarita mix are added to cocktails, dramatically increasing the total sugar and calorie intake. For those watching their weight or blood sugar, sticking to high-quality, un-aged mezcal or 100% agave tequila, and consuming them neat or with a splash of soda, is the best approach.
Potential Health Benefits and Compounds
Beyond the basic nutritional facts, advocates of both spirits point to other potential health-related properties. Both mezcal and 100% agave tequila contain compounds called agavins and fructans from the agave plant.
- Digestive Aid: Traditionally, both spirits have been consumed as a digestif in Mexico. The inulin found in agave is a type of prebiotic fiber, which can aid digestive health by promoting the growth of beneficial gut bacteria. However, the distillation process reduces much of the inulin content.
- Probiotics and Prebiotics: Some studies suggest that the fructans in agave can act as both probiotics and prebiotics, fostering a healthy gut microbiome. This benefit is most pronounced in high-quality, pure spirits. Mezcal, especially artisanal varieties, is sometimes said to contain more of these trace plant compounds due to its less industrial production process.
- Lower Glycemic Impact: For individuals managing their blood sugar, high-quality agave spirits offer a relatively low-glycemic option, as the agavins and fructans are less easily absorbed than other sugars.
- Gluten-Free: For those with gluten sensitivities or celiac disease, both spirits are a safe choice, as they are naturally gluten-free due to their agave-only base.
Mezcal vs. Tequila: A Comparison Table
| Feature | Mezcal (Artisanal) | Tequila (100% Agave) | Tequila (Mixto) |
|---|---|---|---|
| Agave Type | Any of 30+ species | Only Blue Weber | At least 51% Blue Weber |
| Production | Roasting in earthen pits; often handcrafted | Steaming in industrial ovens; may use modern techniques | Steaming in industrial ovens; relies on modern techniques |
| Additives | None (by law) | None (by law) | Up to 49% non-agave sugars |
| Flavor Profile | Distinctly smoky, complex, earthy | Agave-forward, often crisp or sweet | Varies; can be harsh due to additives |
| Trace Compounds | More likely to retain artisanal, trace elements | Retains some; industrial process may reduce amount | Likely very minimal due to additives |
| Purity | Higher purity standard | High purity standard | Lower purity standard |
The “Healthiest” Choice: It Depends
Ultimately, whether mezcal is healthier than tequila largely comes down to the quality and how it's consumed. For purists who prioritize traditional methods and avoid additives, mezcal is often seen as the cleaner, more artisanal spirit. The regulations requiring 100% agave for mezcal guarantee a pure product. However, for those who seek the same purity in tequila, opting for a bottle clearly labeled "100% agave" is crucial, as this eliminates the risk of hidden additives present in mixtos.
It's important to remember that alcohol is not a health food and any perceived benefits are only possible with moderate consumption. The best choice for a health-conscious consumer is a high-quality, unmixed version of either spirit. The "healthiest" approach isn't about choosing mezcal over tequila or vice versa, but about being an informed consumer, understanding the production methods, and prioritizing purity and moderation in your drinking habits. The unique flavor and heritage of mezcal offer a compelling reason to explore it, but a top-shelf 100% agave tequila can offer a similarly clean drinking experience.

Responsible Drinking is Key
No matter which agave spirit you choose, the context of your consumption is paramount. Sipping either mezcal or 100% agave tequila slowly, rather than drinking shots, allows you to better appreciate the complex flavors and helps in monitoring your intake. Avoid sugary cocktails and opt for minimal mixers like fresh lime juice or a light, natural soda. The perceived "health benefits" of either spirit should never be a justification for heavy drinking, as excessive alcohol consumption carries serious health risks. A mindful approach to sipping, appreciating the craftsmanship and tradition in every glass, is the healthiest way to enjoy these storied Mexican spirits.
Conclusion: The Purest Sip Wins
When comparing mezcal and tequila from a health perspective, the truest indicator is a spirit's purity—specifically, whether it is made from 100% agave with no added sugars. Artisanal mezcal has a built-in advantage, as its traditional production mandates 100% agave, while consumers must be diligent in selecting 100% agave tequila to avoid additives. Both can offer a clean, low-calorie, and low-carb experience when enjoyed neat or with simple mixers. Choosing between them comes down to personal taste and a preference for either mezcal's smoky, earthy complexity or tequila's distinct Blue Weber agave profile. When making your choice, remember that responsible consumption is the most important factor for your well-being.
