How much wine, in ounces, constitutes one standard drink?

One standard drink of wine is typically defined as 5 ounces. This measurement is based on the alcohol content found in most wines, which is generally around 12-14% alcohol by volume. The standard drink measurement is an important guideline for understanding alcohol consumption and its effects on health. It helps individuals recognize how much alcohol they are consuming and encourages responsible drinking habits. In contrast, other measurements such as 10 oz, 7 oz, and 12 oz significantly exceed the standard drink definition, potentially leading to misunderstandings about alcohol intake and its effects.
