How long can you keep red wine for cooking once the bottle is opened?

[FlippetyFlipFlaps]

Hi,

I often like to keep a bottle of red wine handy for adding to sauces while cooking. I made a casserole about two weeks ago using a bottle, and was thinking of making a bolognese tomorrow using a bit from the same bottle.

Is is OK or could I make myself and the rest of my family ill if I use it? Generally how long does red wine keep for cooking purposes once the bottle is opened?

Thanks for your help in advance!

I keep it for months.

I freeze the leftovers in ice cube trays.

IME, a bottle of red wine will go off (turn more acidic) in about half a week unless stopped with a vacuvin or similar. You won't get ill by using it, but it will be akin to pouring vinegar into your sauce, which might not be that appealing. If you wanted to keep small quantities of wine to use for cooking and don't have a bottle of wine in quick rotation, just freeze small quantities of wine to use later.

if it's a screw-top bottle & kept in the fridge, it should last quite a while without turning to vinegar?

(hope so as I have one there just now!)

Left over wine? Am I missing something?

erm? Wine storage? WTF?

Duhrink it!

I freeze it too, in little food bags. You can just add to sauces when you need to then. it also made a nice alco slushy one summer evening once

in my case the left-over wine was the cheapest thing in the shop, bought specially for cooking

I shouldn't dream of drinking it. I have drinking wine for that
