How Much Red Wine Is Safe to Drink Each Day?

Many people enjoy a glass of red wine with dinner, often citing potential heart benefits. But how much is actually safe? According to the Centers for Disease Control and Prevention (CDC), moderation is key. For adults of legal drinking age, the Dietary Guidelines for Americans recommend limiting alcohol intake to no more than two drinks per day for men and one drink per day for women.

When it comes to red wine, one standard drink is defined as 5 ounces (about 150 milliliters), typically with 12% alcohol by volume. That means, for most women, a single glass a day is the upper limit of what’s considered safe. For men, it’s up to two glasses—but not every day without consideration of overall health.

It's important to note that “moderation” doesn’t mean drinking every single day. The guidelines emphasize that some adults can choose not to drink at all—and that’s perfectly healthy, too. In fact, the CDC stresses that no one should feel obligated to drink for perceived health benefits. Any potential cardiovascular perks from red wine, often linked to antioxidants like resveratrol, can usually be outweighed by the risks if consumption goes beyond moderate levels.

Exceeding recommended limits—even occasionally—can increase the risk of liver disease, certain cancers, and cardiovascular problems over time. And for some individuals—such as pregnant women, people with specific medical conditions, or those on certain medications—any amount of alcohol can be unsafe.

The bottom line? If you choose to drink red wine, keep it in check: one glass for women, up to two for men, and always within the context of a balanced lifestyle. But remember, not drinking at all is just as healthy—and often safer.
