How long does wine last for cooking?

[tntcoder]

Hi,

Simple question How long will an open bottle of wine (screw-top) last for cooking purposes if kept refrigerated?

I know for drinking purposes the oxygen screws it over after a couple of days, but will it still do for 2 hour slow cook bolognese / stews after maybe 1-2 weeks?

Thanks!
