Excessive air in your open bottle of wine can cause your wine to oxidize. Depending on the amount of air in the open bottle, wine can go “off” in as little as 24 hours or as long as a week. Spoiling of your open wine can be delayed by ensuring it is firmly capped and/or storing it in the refrigerator.
To avoid spoilage of open wine, many customers use a vacuum wine pump which pumps the air out of the partially full bottle to create a vacuum seal. Wine pumps are widely available in retail stores.
Wine Kitz Iris carries Vacuum Wine Pumps for $14.00 each.
Cellar your wine in the coolest, quietest, darkest place available in your home. The warmer the environment the faster your wine will age. Temperature fluctuations of more than 10°F / 6°C can spoil wine, so find a place that has a consistent temperature and humidity level.
