How Long Does Tomato Juice Last? We've been buying tomato juice in smaller containers and now decided to buy bigger ones.  But, when we went to the store the tomato juice says that it only lasts two weeks in the fridge.  Expiration dates always err on the side of caution.  How long can we expect to keep it after we have opened it?
According to this website, 5 to 7 days in the fridge.
