Soaking onions in red wine does have the health care value of anti-oxidation, cleaning blood vessels, supplementing vitamins and lowering blood fat.

But the best way is to drink red wine with raw onions. Because at this time, fresh red wine and onions have not been oxidized, which is the best time for their nutrients and taste, and is the best way to eat with health care.

In addition, onions are not easy to soak for too long, and it is best to drink them within one week.

Because wine is in contact with air for a long time, oxygen in the air will make wine oxidized and taste worse. It is safest to finish drinking red wine within one week. Onion is an unpasteurized raw food. Although soaking in red wine will not go bad for a short time, it will produce bad taste or even rot after a long time. So don't soak red wine in onions for too long.

Red wine soaked in onions can be drunk in 1-2 days. Don't soak too much at a time. Drink it before soaking.
