Waste not, want not: Keeping wine fresh after opening

Extend the life of your opened wines with these handy preservation tips.

There’s nothing quite as disappointing as having to throw out a half-full bottle of wine because it has spoiled after being opened for some time.

This doesn’t have to be a common occurrence when you can’t finish a wine though – there are some steps you can take to preserve it for longer!


Once the bottle is uncorked, the countdown begins!


Quite simply, the element that keeps us alive causes our wine to go off! Exposure to oxygen flattens the wine, making it lose its aroma, body and flavour.

While oxygen can play a big part when it comes to wine tasting, allowing the beverage to ‘open up’ when it’s swirled around the glass, it’s a different story when the bottle is left open for some time.


What should I avoid doing to make it last longer?

Don’t leave your bottle sitting on your kitchen bench; once it’s opened, store it in your climate-controlled wine cabinet, ideally at correct serving temperature i.e. 6°-8° for whites, and 14°-18° for reds. If in doubt, a bit cooler is better – as your wine will always warm up a few degrees by the time you serve it.

Storing it in a lower temperature slows the action of bacteria that can spoil the wine and turn it into vinegar.

Avoid laying your wine bottle on its side once opened, as this can increase the surface area that is exposed to oxygen, and also can cause leakage. Store the bottle upright in your wine cabinet or fridge instead.

Also remember to keep it out of sunlight, as this can cause the wine to quickly spoil and discolour.

How can I preserve my opened wine?

There are a number of things you can do to extend the life of your red, white or sparkling, which can include a mix of smart wine storage tips and special preservation tools.

Here are two ideas to help you extend the life of your wine.


1) Re-cork immediately after pouring, and then seal with an inert gas

Prevent more oxygen from seeping in by re-corking the bottle every time you pour a glass.

Once you’re done drinking, seal the wine using an inert gas such as argon or nitrogen e.g. Winesave (insert the gas pressing the nozzle on the canister for about 1 sec), recork, then store your sealed wine bottle in your climate-controlled wine cabinet (or in the fridge), as this will help the wine last anywhere between 3 and 7 days.


2) Invest in a WineArt Wine Preservation System

If you’re passionate about your wine and don’t want to waste a single drop, you may want to consider investing in a WineArt Wine Preservation System.

This is a must-have wine accessory for any oenophile, with this unique technology able to keep your opened bottles of wine preserved, in perfect condition, for up to 10

The WineArt keeps your bottle under vacuum and at perfect drinking temperature, so you can go back for seconds – and thirds – when you feel like it! So it’s the perfect solution for those who don’t want to finish the entire bottle… and for those who might wish to open and enjoy several different wines.

Simply place the opened bottle into one of the WineArt’s two compartments, select the temperature (8 degrees for white or rose, 18 degrees for red), lower the vacuum heads (a perfect seal will form around the top of the bottle) and activate the oxygen extraction process. What makes the WineArt work so effective is that the vacuum is equipped with a pressure sensor and will re-engage regularly to maintain a perfect vacuum.


3) Transfer the rest of your bottle to smaller bottles

A nifty trick to minimise exposure to oxygen, a favourite of James Halliday’s, is to transfer the rest of your bottle into half-bottles you’ve kept on hand, filling them to the brim, and then recorking/sealing them. Stored in this way, in a cool environment, your wine should stay in pretty good condition for about 4-5 days.
