Question

Once a bottle of wine has been opened, how long before it becomes unfit or toxic to drink?

Answer 1

oxygen is wines worst enemy.  if you keep white wine corked in the fridge it should be ok for 5-7 days.  red wine should be kept around 65-68 degrees.  even better if you get a vacu-vin system to suck all the air out of the bottle (very cheap in the grocery store).

it will not become toxic.  it will just taste like vinegar!!!

Answer 2

Both of the previous answers are pretty accurate. Also, I have found the Target brand wine that comes in the "wine cubes" is wonderful. It also stays fresh for atleast 2 weeks or longer.

Answer 3

Unfit - Depending on your standards...12 hours at room temperature or up to 2 weeks refrigerated.

Toxic - Unless foreign substances like mold are introduce, it will never become toxic. Unpleasant yes.
