First let's look at why wine goes off and goes bad once the screw cap has been opened or the cork popped.
These are both chemical reactions, so if you lower the temperature, the reaction will be slower- that means: keeping your wine in the fridge will make it last longer.
Here is my guide to how long each wine type will last after being opened.
Red wines can last 3–5 days in a cool dark place sealed with their screwcap.
The more tannin and acidity the red wine has, the longer it tends to last after opening.
So, a light red with very little tannin, such as Pinot Noir, won’t last open as long as a rich red wine, like Shiraz.
Some wines will even improve after the first day open.
Store open red wines in a dark cool place after opening them.
If you don’t have a wine cellar, your fridge is better than letting wine sit out in a 21+°C room.
Sparkling wines can last 1–3 days in the fridge with a sparkling wine stopper
Sparkling wines lose their fizz quickly after opening. A traditional method sparkling wine, like ours or a Champagne, will last longer than a tank method sparkling wine, like Prosecco.
I have found the best Champagne Sealer, I've spent years trialling various closures/ ways to seal sparkling wine, and this one is the very best I've found.
Your sparkling wine will now last up to 5 days.
Unoaked white wine or rosé can last 5–7 days in the fridge sealed with the screwcap.
Off dry white and rosé wines will be drinkable for up to a week when stored in your refrigerator.
The taste will change subtly after the first day, as the wine oxidizes.
Overall the fruit character of the wine tends to diminish, becoming less vibrant.
Chardonnay or a full-bo3–5 days in fridge sealed with the screwcap.
Full-bodied white wines, like oaked Chardonnay, tend to oxidize more quickly because they saw more oxygen during their pre-bottling aging process.
Make sure you keep them sealed and in the fridge.
If you drink a lot of this type of wine, it’s a really smart idea to invest in an Argon Gas canister.
Fortified wines can last 28 days in a cool dark place, sealed with a cork.
Fortified wines like Port and Muscat have very long shelf lives because of the addition of brandy.
Just so you know, the sweeter the dessert wine, the longer it will last open.
