Drinking 200 ~ 300 ml a day is just right. If you want to be addicted to 400 ml, you can, but you can't do it every day. More than 500 ml at a time will only be harmful to the health. Red wine is usually drunk within 2 days after opening, and the "life" of real red wine after opening is only 6 to 8 hours. It's not that you can't drink it after a few hours, but its unique "fruity fragrance" and "fresh breath" will gradually lose with the oxidation process in these hours.
