It’s a common question when enjoying a drink: how much alcohol are you actually consuming? Many people find it surprising to learn what truly constitutes a single serving of alcohol, especially when it comes to different types of beverages. While a pint of beer and a shot of spirits are both alcoholic drinks, they contain vastly different amounts of pure alcohol. This difference highlights why the size of the container doesn’t tell the whole story about alcohol content.
For instance, you might think a light beer is significantly weaker than a regular beer. However, the alcohol content difference is often minimal. Consider these examples of alcohol by volume (ABV):
- Regular beer: Around 5% ABV
- Many light beers: Approximately 4.2% ABV
- Some craft beers: Can go as high as 10% ABV
This means a 12-ounce bottle of beer at 10% ABV actually contains twice the alcohol of a 12-ounce bottle at 5% ABV. To standardize and simplify understanding, health organizations have established the concept of a “standard drink.” In the United States, one standard drink is defined as containing roughly 14 grams, or 0.6 fluid ounces, of pure alcohol.
This standard measurement helps in understanding recommended consumption guidelines. So, how does this translate to hard alcohol, also known as distilled spirits?
When it comes to hard alcohol, such as whiskey, vodka, gin, rum, or tequila, one standard drink is typically 1.5 ounces. This is based on the standard 40% alcohol by volume for most spirits. Therefore:
- A 1.5-ounce shot glass of 80-proof (40% ABV) distilled spirits equals one standard drink.
Let’s put this into perspective with other common alcoholic beverages:
- Beer: A 12-ounce can of regular beer (around 5% ABV) is one standard drink.
- Wine: A 5-ounce glass of wine (around 12% ABV) is one standard drink.

Each of the drinks pictured above represents one standard drink in the U.S., all containing 0.6 fl oz or 14 grams of pure alcohol. The alcohol by volume (alc/vol) differs across drink types. While these standard drink measures are useful for health advice, typical serving sizes can sometimes be larger.
Understanding standard drink sizes, especially for hard alcohol, is crucial for making informed choices about your alcohol consumption and staying within recommended health guidelines. For further information and resources on responsible drinking, visit Rethinking Drinking.
