Extending the life of your leftover wine
Anyone who enjoys wine has at some point wondered how to keep wine fresh after opening a bottle and drinking only a portion of it. While oxygen is a vital component to opening up the flavor of a wine when it has just been opened and poured, the same chemical reaction will quickly begin to degrade your wine. Left too long, any wine left unfinished in the bottle and exposed to oxygen will begin to take on an acidic and vinegar taste.
There are quite a few wine preservation systems available to help you extend the life of your wine after the bottle has been opened. By choosing a system that works well for you, you can keep your favorite wines fresh to enjoy for more than one evening at a time.
Re-cork & Refrigerate
Simply re-corking and refrigerating the remainder of a bottle of wine can keep it reasonably fresh for a short period of time. For wine drinkers who only need to preserve a partial bottle from one evening to the next, this solution is often the only one necessary.
If you typically enjoy reds or wines that are best served at room temperature, keep the proper glasses on hand. When served in the correct type of wine glass, a chilled red will warm to room temperature fairly quickly just from the warmth of your hand on the glass. This will allow you to still enjoy your favorite wine at the appropriate temperature while easily preserving it in the refrigerator from one evening to the next.
Re-corking and refrigerating your open bottle of wine is only recommended for up to 24 hours. When you wish to preserve an open bottle for a longer period of time, choosing the right wine preserver is essential.
