Dan Murphy’s: How long wine lasts once opened – and how to make it last longer

A wine merchant has revealed how long different drops last once opened — and how to keep them fresh for a little longer.

Sean Menzes, of Australia, said that when a wine bottle is broken open, oxidation begins to take place – a chemical reaction in which the wine is exposed to oxygen.

How long the alcohol lasts depends on the type of wine, how it is stored and how much is left in the bottle.

Mr Menzes told the Australian alcohol salesman Dan Murphy’s an open bottle of white wine or rosé will last between three and five days if kept cool in the refrigerator.

Sparkling wine only lasts one to two days once opened, so it’s best to invest in a good quality bottle stopper or enjoy a bottle with others.

In the winter, opened bottles of red wine last between four and five days, but in the summer two to three days due to the heat.

It is also recommended to store red wine in a dark place, whether it is open or closed.

Fortunately, there are a number of ways to extend the shelf life of your leftover wine.

The age-old trick of putting a teaspoon into the neck of an open bottle of wine won’t do much, so Menzes recommends buying a bottle stopper.

If you only have one or two glasses left in a 750ml bottle, you may be able to transfer them to a smaller bottle.

This will reduce the surface area and amount of air in the bottle to slow down the oxidation process.
