How many glasses of wine per day is OK?
A recent analysis of studies found the optimal daily intake of wine to be 1 glass (150 ml) for women and 2 glasses (300 ml) for men. Drinking this moderate amount of wine is associated with health benefits, while drinking more than that may impact your health ( 21 ).
Experts say a a good maximum amount of wine for women would be a 5 oz glass of wine, and for men two 5 oz glasses of wine, no more than several times a week. Experts strongly advise women against having more than 3 drinks of wine per day, and for men, 4 drinks of wine per day.
Drinking, even in moderate amounts, can still have catastrophic outcomes. It's safe to stick to a standard of no more than three glasses of wine per day, but limiting alcohol consumption may also promote more healthy living habits.
While the consensus on wine is polarizing, researchers do say that drinking it in moderation is not bad for you. In general, moderate wine consumption for healthy adults means up to one drink a day for women and up to two drinks a day for men. One drink is equal to five fluid ounces (148 mL) of wine.
"What is certain about wine and other types of alcohol is that drinking beyond moderation has clear impacts on a person's health," warns Dr. Septimus. "Regularly drinking more wine than recommended increases a person's risk of developing cancer, liver disease, chronic pancreatitis, sleep disorders and more."
Drinking wine every night can lead to weight gain, decreased immune function, and mental health issues [1]. Additionally, having more than a few drinks daily can affect liver health, resulting in liver damage or liver disease [2].
A note on drinking level terms used in this Core article: The 2020-2025 U.S. Dietary Guidelines states that for adults who choose to drink alcohol, women should have 1 drink or less in a day and men should have 2 drinks or less in a day.
In relation to the question, a bottle of wine is 750ml and taking the WHO recommendation of a standard drink of wine being 140ml - that would mean each bottle has 5.4 standard drinks. So half a bottle (~2.7 glasses) each night is over the health recommendations.
Drinking a bottle of wine per day is not considered healthy by most standards. However, when does it morph from a regular, innocent occurrence into alcohol use disorder (AUD) or alcoholism? First, it's important to note that building tolerance in order to drink an entire bottle of wine is a definitive red flag.
Effects of Alcohol
Two glasses of wine, each no more than 4 or 5 ounces, may make you more relaxed and talkative but also slightly less coordinated and less able to concentrate.
