How to Preserve an Open Bottle of Wine
One of the reasons we like screw caps for wine bottles is because they make it easier to store half finished bottle of wine. Corks, however, are still a preferred choice of closures for bottles putting us in dilemma as to how to preserve the unfinished bottle.
Ideally, we would always suggest that you finish a bottle of wine rather than keeping it for another day, but it is not always possible. The aim of keeping wines closed at all times is to avoid unnecessary oxidation which reduces the longevity of a wine. Despite that an open bottle of wine will not last more than 2-3 days maximum, irrespective of closure.
When you uncork a bottle of wine do not discard the cork. Once you’ve poured yourself a glass replace the cork. It may be difficult but always use the wine end of the cork to close the bottle. The other side will be easier to use and looks clean but it has been exposed to the elements during transit and isn’t as hygienic as you may think it is.
Purchase a few bottle closures especially which allow some vacuum to be created in the bottle. Once you are done with your share of drinking, use these closures to seal the bottle.
A company named Vacu Vin has a range of closures known as Wine Savers which allows you to pump out air from the bottle and then sealing it. You will find these closures commonly being used at restaurants and are worth the investment if you often find yourself with unfinished bottles of wine.
Always put the half bottle of wine in the fridge. Even though the oxidation process of the wine will continue, it will be at a much slower pace as compared to leaving the bottle in outside temperature.
Empty Wine into a Half Bottle
It may seem cumbersome but, pouring your leftover wine in a smaller bottle or half bottle is a good idea. It reduces unnecessary exposure to oxygen and therefore help preserve the wine for a while longer.
There are other ways to preserve wine, but they are complicated, tedious and require using gases like nitrogen and argon. A layer of these gases blocks any interaction that a wine may have with oxygen.
If you don’t see yourself finishing your bottle of wine anytime soon you can always use them in cooking. Check out these recipes.
