How many ounces are typically in a standard drink?

The standard drink is often defined based on the amount of pure alcohol it contains rather than the total volume of a beverage. In the context of most guidelines, a standard drink typically contains 0.6 ounces of pure alcohol, which is approximately the amount found in a 12-ounce beer (about 5% alcohol), a 5-ounce glass of wine (around 12% alcohol), or a 1.5-ounce shot of distilled spirits (about 40% alcohol). This measurement is important as it helps individuals understand their alcohol consumption and allows for responsible drinking practices.

The other options list amounts of pure alcohol that do not align with the standard definitions used in public health guidelines, making them less applicable in understanding the typical serving size for alcoholic beverages.
