Understanding the Standard Drink
To accurately compare a shot of tequila and a glass of wine, it is essential to understand the concept of a "standard drink." In the United States, a standard drink contains 0.6 fluid ounces (14 grams) of pure ethanol. This is the key metric used by health organizations, such as the CDC and NIAAA, to measure alcohol consumption consistently across different types of beverages. The standard drink equivalences are as follows: a 1.5-ounce shot of 80-proof (40% ABV) distilled spirits, a 5-ounce glass of 12% ABV wine, and a 12-ounce can of 5% ABV beer. This metric is the cornerstone of the comparison, proving that in terms of pure alcohol, a standard 1.5-ounce shot of tequila is indeed equivalent to a standard 5-ounce glass of wine.
Beyond the Standard: Volume and Strength Variation
While the standard drink provides a baseline for comparison, real-world drinking often involves significant variation. The alcohol by volume (ABV) in wine, for instance, is not fixed at 12%. It can range widely, from around 5% to 14.5% or even higher for fortified wines. Similarly, tequila can be found at higher proofs, increasing the alcohol concentration in a single shot. The vessel in which a drink is served also plays a role. A restaurant's "glass" of wine might be larger or smaller than the 5-ounce standard, and a bartender's free-pour shot can contain more or less than the standard 1.5 ounces.
Calorie and Nutritional Comparison
Beyond pure alcohol, the caloric and nutritional content of tequila and wine presents another area of difference. The calories in alcohol itself are significant, with alcohol providing about 7 calories per gram, nearly as much as pure fat. However, the total calories of a drink depend on its ingredients. Straight, 100% agave tequila contains no sugar or carbohydrates, making it a lower-calorie option per standard drink than many wines. A standard 1.5-ounce shot of 80-proof tequila has approximately 97 calories. In contrast, a 5-ounce glass of wine (at 12% ABV) typically contains between 120 and 125 calories, with red wine sometimes being slightly higher. The sugar content in wine also varies, with sweeter varieties having more calories from sugar.
Tequila vs. Wine: What the Experts Say
When it comes to the purported health aspects, opinions vary among nutritionists and experts. Some point to the antioxidants found in red wine, like resveratrol, as a potential health benefit, although the amount needed for any significant effect is far greater than what is found in a typical glass. Other experts favor 100% agave tequila for its low glycemic index and lack of sugar and carbs, which can be a better choice for those concerned about blood sugar spikes. The final decision often comes down to individual health goals and preferences, but it is clear that neither should be considered a "health food". The adverse health risks of excessive alcohol consumption, including liver disease and certain cancers, can outweigh any minor perceived benefits.
Conclusion
While a standard 1.5-ounce shot of 80-proof tequila and a standard 5-ounce glass of 12% ABV wine contain the same amount of pure alcohol and are therefore equal in this specific metric, their overall composition and health implications differ. Tequila generally offers fewer calories and no sugar per standard drink, especially when consumed straight, whereas wine, particularly red wine, contains antioxidants. The critical takeaway for responsible consumption is to focus on the pure alcohol content, which is identical in standard servings of each beverage. Ultimately, understanding these differences empowers you to make informed decisions about your alcohol intake, regardless of your drink of choice.

| Sugar | 0 grams (for 100% agave) | Varies, typically 1-2 grams |
| Carbohydrates | 0 grams (for 100% agave) | Varies, typically 4-5 grams |
| Vessel Volume | 1.5 ounces | 5 ounces |
| Mixing Potential | Often mixed (margaritas) | Often consumed neat |

Smart Drinking Choices
Mindful Consumption
Whether you choose tequila or wine, being mindful of your alcohol intake is crucial for your health. The concept of a standard drink serves as a valuable tool for tracking how much pure alcohol you are actually consuming, helping you to make more informed choices.
Calorie Awareness
For those watching their caloric intake, opting for straight 100% agave tequila is a more calorie-efficient option per standard drink than wine, which often contains additional sugars and carbs. However, this is only true if mixers are not added, as a sugary margarita will significantly increase the calorie count.
The 'Buzz' Factor
The rate at which you consume alcohol can affect how it impacts you. Since a tequila shot is consumed quickly, the alcohol is absorbed into the bloodstream faster, leading to a more immediate feeling of intoxication. A glass of wine, sipped slowly over a longer period, results in a more gradual effect.
Hydration is Key
No matter the alcohol, drinking water between alcoholic beverages is always a good practice. It helps you pace your drinking and mitigates the dehydrating effects of alcohol, which can contribute to hangovers.
Know Your Limits
Every individual's body processes alcohol differently based on weight, food intake, and metabolism. The standard drink is a guideline, not a hard and fast rule for how a person will feel or react. It's essential to listen to your body and know your own limits.
