We love a chilled glass or more of wine every evening, but there have been times when we have not been able to finish the whole bottle, and found it had turned overnight. And there is really nothing worse than letting a delicious bottle of wine go to waste. So here’s how you can enjoy your wine and keep it fresh after opening for those times when you can’t finish the bottle.

Wine goes bad when it comes in contact with oxygen. This is because wine requires a delicate balance of oxygen exposure. While oxygen is crucial in the fermenting process and can boost flavours and aromas of a wine once opened, too much can turn your wine into vinegar.

Here are some easy steps to keep your wine fresh for longer.

Always, And We Mean Always Re-cork Your Wine

If you know that you’re not going to finish that bottle, keep it closed. It can be easy to leave the cork off until you’re ready to put the bottle away, but re-corking the bottle immediately after each glass is the best way to ensure your wine doesn’t go bad. Limiting the amount of oxygen that’s in contact with your wine helps keep its flavour fresh for longer.

Keep That Bottle Of Wine Upright

Avoid storing your wine lying down. An upright position helps minimise the surface area that’s exposed to oxygen, slowing the oxidation process.

Keep That Opened Bottle In A Cold And Dark Place

Oxygen isn’t the only factor when it comes to maintaining a wine’s integrity – light and temperature play a part, too. Keep your open wine bottle out of the light and store it below room temperature, like in the refrigerator. This slows down the process of wine oxidizing since the molecules are now moving very slowly. This works for both reds and whites—but this method only works for open bottles. The fridge is not recommended for long-term wine storage.

Consider Purchasing A Wine Preserver

If you’re serious about preserving your wine, it might be worth investing in a wine preserver. There are two common systems – the vacuum pump and an inert gas preservation system. A vacuum pump works by removing some excess gas from the bottle after it has been opened. A vacuum pump is relatively inexpensive and retails for around $25-35 and, while not perfect, it can add a few days to the life of your wine.

How Do I Tell If My Wine Has Turned?

Sometimes it can hard to tell whether or not your wine has gone bad in the first place. The process of oxidation changes a wine’s colour and taste, but that doesn’t always mean your wine has gone bad.

Check the colour of your wine. Reds will begin to darken to brown and brick tones, while white wines will often deepen and become more yellow. Give it a taste-test. When a red wine has gone ‘off,’ you will notice a flat taste to its flavour and aroma. White wine’s on the other hand will start to develop a sour, vinegary taste.

So don’t feel bad if you can’t chug down the whole bottle, so long as you follow the tips above, you should be able to enjoy your bottle for a few more days.
