Question: how long does red wine stay good after you open it?
Answer: How long red wine lasts once opened: 3-5 days. The tannins and acidity in red wine help preserve them for longer than sparkling wines and white wines. Rich, full-bodied reds such as Shiraz or Cabernet can last for up to 5 days when corked or resealed, and stored in a cool, dark place.
