When you pick up a bottle of wine, you must be confused about the shelf life after opening the bottle, and mark it above: After opening the bottle, please feel
as if you are drinking as soon as possible. How long can a bottle of wine be opened? Will it be spoiled?
1.Does expired wine affect people ?
For wine, shelf life is closely related to the way of storage and the type of wine. Of course, some wines with special treatment can last up to a month, but 3-5 days
is the limit, but don't worry too much, after this period of time, the wine will not cause any harm to health.
2.Why does wine go bad?
Wine usually spoils for two reasons. When acetic acid bacteria interact with alcohol, can differentiate acetic acid and acetaldehyde, make the taste become pungent,
produce strong vinegar taste; In addition, wine contact with the air will destroy the original aroma, and even give off the smell of rotten fruit. Both are formed by
chemical reactions, and the only way to slow them down is to keep them in the cold.
After opening the bottle, sparkling wine will quickly lose carbonic acid, making the bubble less and less, so the shelf life is very short. If it is sealed with a bubble
stopper, it can only be placed in the refrigerator for 1-3 days.
If it is stuffed into a cork and iced in the refrigerator, it can last for about 5 - 7 days, and this type of wine is stored in the refrigerator, basically saving for a week is not
a problem. However, after the wine begins to oxidize, the overall fruit aroma will also decline, gradually losing its original flavor.
The only ones that can be preserved for a long time without affecting the quality of the wine are Marsala and Madeira, which are already oxidized and heated during
bottling. In the same way, putting precious wines in the shade and in the fridge is definitely the best way to take care of them.
*Rich Liquor
Store in a refrigerator with a cork stopper for 3 - 5 days. White wines with a richer taste, such as Chardonnay and Viognier, have a relatively high oxidation rate due
to the high volume of oxygen in the bottling process. If you really like this type of wine, then really recommend buying a vacuum plug!
Sealed in a cork game and placed in a cool place or in a refrigerator, it can be stored for 3 - 5 days, but never in a room above 21 °C. The higher the acidity of the red
wine and the higher the acidity, the slower the oxidation rate, so red wine with less tannins, such as Pinot Noir, can be stored for a shorter time than Petite Sirah.
Although it seems elegant to put these noble wines on the bookshelf, it will make them more susceptible to flavor loss than exposure to light and heat.
The only ones that can be preserved for a long time without affecting the quality of the wine are Marsala and Madeira, which are already oxidized and heated during
bottling. In the same way, putting precious wines in the shade and in the fridge is definitely the best way to take care of them.
