Demystifying the Hard Seltzer Effect
Hard seltzers like Truly have gained immense popularity as a low-calorie alternative to beer or cocktails. Their often refreshing, fruity flavors can lead some to underestimate their alcohol content. A typical can of Truly contains 5% Alcohol by Volume (ABV), which is comparable to many standard beers. While this is a modest amount, the idea that a single one could cause intoxication is not as far-fetched as it seems for some individuals. The human body's response to alcohol is highly variable, and several factors determine how much is needed to feel the effects.
What Constitutes a Standard Drink?
To understand the impact of a single Truly, it's helpful to know what the National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines as a standard drink. This provides a universal baseline for alcohol content and helps clarify how different beverages compare.
- One 12-ounce beer: Typically 5% ABV, similar to a standard can of Truly.
- One 5-ounce glass of wine: Approximately 12% ABV.
- One 1.5-ounce shot of distilled spirits: About 40% ABV.
As you can see, a Truly is a standard drink. The misconception arises because people often drink hard seltzers more quickly than, for example, a shot of liquor. The speed of consumption directly impacts how quickly alcohol is absorbed into the bloodstream.
Factors Affecting Intoxication from a Single Drink
For a person with low tolerance, or under certain circumstances, a single drink can be enough to reach the lower levels of intoxication, sometimes referred to as being "buzzed" or having "subclinical intoxication". The feeling of euphoria or relaxation can begin at a blood alcohol concentration (BAC) as low as 0.03-0.05%. Here's a deeper look into the variables at play:
- Body Weight and Composition: A person's body size significantly affects how alcohol is distributed. Those with a lower body weight and less lean muscle mass have less body water to dilute the alcohol, leading to a more concentrated blood alcohol content.
- Gender Differences: Women typically have a higher body fat percentage and less body water than men. They also produce less of the enzyme alcohol dehydrogenase, which helps break down alcohol in the stomach. These physiological differences mean women often reach a higher BAC than men after consuming the same amount of alcohol.
- Food in the Stomach: Drinking on an empty stomach allows alcohol to be absorbed into the bloodstream much faster. Having food, especially high-protein or fatty foods, slows this process by keeping the alcohol in the stomach longer.
- Speed of Consumption: The rate at which you consume alcohol is critical. Sipping one Truly over an hour gives the liver time to metabolize the alcohol. Conversely, chugging it quickly overwhelms the liver and causes a rapid spike in BAC.
- Carbonation: Interestingly, carbonated beverages like hard seltzers can speed up the rate of alcohol absorption. The fizz increases pressure in the stomach and small intestine, pushing alcohol into the bloodstream more quickly.
- Tolerance and Genetics: Regular drinkers may develop a higher tolerance, meaning they need more alcohol to feel the same effects. Conversely, someone with little to no experience with alcohol will feel the effects much more profoundly. Genetic factors can also affect how efficiently the body metabolizes alcohol.
- Overall Health and Fatigue: Being tired, dehydrated, or under a lot of stress can make you feel the effects of alcohol more strongly.
Understanding Blood Alcohol Concentration (BAC)
BAC measures the percentage of alcohol in a person's bloodstream. Legal impairment in many places is defined at a BAC of 0.08%, but effects begin at much lower levels. For the average person, one standard drink can increase BAC by about 0.02%. Therefore, someone with a very low body weight or low tolerance could potentially reach a BAC of 0.04-0.06% after one drink, putting them in the range of feeling relaxed or slightly impaired.
Hard Seltzer vs. Other Beverages: A Quick Comparison
| Drink Type | Standard Serving Size | Approximate ABV | Standard Drinks | Key Absorption Factor |
|---|---|---|---|---|
| Truly Hard Seltzer | 12 oz. can | 5% | 1 | Carbonation speeds absorption |
| Standard Beer | 12 oz. bottle | 5% | 1 | Generally slower absorption than seltzer |
| Glass of Wine | 5 oz. glass | 12% | 1 | No carbonation; rate depends on food |
| Shot of Liquor | 1.5 oz. | 40% | 1 | High concentration leads to faster onset |
Can One Truly Get You Drunk? The Conclusion
For the vast majority of people, drinking a single Truly is unlikely to lead to severe intoxication. However, dismissing the possibility entirely is a mistake. For someone with a small body, low tolerance, and on an empty stomach, a single can of this carbonated, 5% ABV beverage could absolutely be enough to cause noticeable impairment, even if it's just a light buzz. The key takeaway is to understand that the effects of alcohol are highly individualized and can change depending on a wide range of factors. Responsible drinking means being aware of these variables and how they affect your own body.

What happens when alcohol is absorbed into the bloodstream?
When alcohol is consumed, it passes from the stomach and small intestine into the bloodstream. From there, it's distributed evenly throughout the body's tissues and fluids. The liver metabolizes most of the alcohol, but the rate at which this happens is constant—about one standard drink per hour. If you consume more than this, your BAC will rise, and you will become more intoxicated. The presence of alcohol in the bloodstream affects various parts of the brain, leading to the common symptoms of drunkenness, such as slowed reaction times, impaired judgment, and slurred speech.
