Wine Shelf Life and Potential Risks of Consuming Spoiled Wine
Wine enthusiasts often wonder about the best ways to store their favourite bottles, ensuring they can enjoy them at their peak. Here are some essential tips for maintaining the quality and longevity of your wines.
Storing wine horizontally keeps the cork moist, preventing it from drying out and allowing oxygen to pass into the bottle, which can spoil the wine. To store wine correctly, choose a cool and dark place, store corked bottles horizontally, maintain the right humidity (around 60%), and consider using a wine fridge if necessary.
The storage conditions for different types of wine vary. For instance, unopened red wine can last for 2-3 years, while sparkling wine typically lasts for 1-2 days when opened. Non-vintage sparkling wine can last for 3-4 years if unopened, while vintage sparkling wine can last for 5-10 years. Bottled rosé can last for 1-2 years if unopened, and rosé wine can last for 3-5 days when opened. Fortified wine can last for decades if unopened.
Proper storage techniques can significantly extend the shelf life of wine. Maintaining a consistent cool temperature (around 55°F or 13°C), controlling humidity between 60-70%, and avoiding exposure to direct light are key factors. Wine should be stored in a dark, vibration-free environment away from heat sources like ovens and sunlight.
Common signs of spoilage in both opened and unopened wine include changes in color, off smells, and unusual tastes. For example, white wines that turn a deep yellow or brown color, or red wines that shift from vibrant purple-red to dull brown or cloudy orange-brown, are likely spoiled. Spoiled wine may also emit musty, basement-like, or wet cardboard smells, or sweet odors in dry whites indicating spoilage. Taste signs include a vinegar-like sourness, fizzing in still wines, a flat or dull flavor lacking fruitiness, or a sour taste in red wines.
It's important to note that spoilage due to microbes in wine can lead to food poisoning. Symptoms of food poisoning include stomach cramps, nausea, vomiting, diarrhea, fever, and dehydration. Therefore, it's crucial to store and consume wine responsibly.
By following these storage guidelines, unopened wine can be preserved for years depending on type and quality, while opened wine's shelf life can be extended from days to a week or more if re-corked and refrigerated properly.
