how long will white wine (organic)keep in the fridge?

[Holymoly321]

Opened a bottle on Saturday and its been in fridge since. Can I still drink it?

The short answer is "not long in our house"

As to your wine, yes, you can still drink it. Cheers!

surely you can, alcohol is a natural preservative

It won't hurt you if it has turned. Just taste bad.
Have you got a vacuum pump?
