There's a lot of truth to the saying, "the older the wine, the better." However, nothing lasts forever, and even this beverage can spoil over time or due to adverse external factors. What is the shelf life of wine and how should it be interpreted? How should wine be stored, depending on its type, not only to preserve but also to improve its taste and aroma over time?
Can wine expire?
Apparently, the only product fit for consumption regardless of how much time passes is honey. The saying that the older the wine, the better, also suggests that the answer to the question of whether wine can spoil is no. Meanwhile, for many different reasons – improper storage, passage of time, external factors, production errors – it too can become unfit for drinking.
There are various ways wine can spoil, and expiring is just one of them. An entire batch might, for example, contain mold that wasn't detected before bottling. The cork might dry out, allowing oxygen to get inside. A beverage left open too long in a warm place can quickly turn sour, and a refrigerator actually does little to extend its shelf life – usually from 3 days to a week. Finally, it is the producer, based on their experience and knowledge, who determines how long wine can age under optimal conditions.
Does wine have an expiration date?
It's worth knowing about the shelf life of red and white wines, as well as younger varieties like sparkling wine – the expiration date is just one guideline. Some producers – especially of light wines – choose to include a 'best before' date on the label. This means that a well-stored wine can last much longer, but if conditions are not good, it can just as easily spoil after this time.
On the bottle – where the wine's expiration date should be – there might also be information about the wine's aging potential. This means that if the beverage is kept in the manner recommended by the producer, it will only achieve its maximum flavor and aroma after a specific period. After this period, these properties begin to slowly decline.
Does wine spoil even when its aging potential is several decades? Unfortunately, yes, even if it is well-stored – perhaps due to minor oversights in production or if it was poorly stored by the distributor. It's worth knowing how to recognize this.
How to recognize spoiled wine?
Wine that has spoiled definitely changes its most important attributes: taste, smell, and color. Sometimes, yeasts and bacteria, some of which are harmful to health, can proliferate excessively in it. However, it certainly should not be used in such cases for direct consumption or for cooking.
Spoiled wine, among other things:
- tastes moldy, is corked, or sour;
- has a vinegary smell or an earthy aroma of mold; you might detect cabbage and garlic in it;
- changes its color;
- contains mold spores or other undesirable elements;
- contains bubbles, which are the result of spontaneous and unplanned fermentation.
In such cases, a small sip of the beverage – accidental or to confirm spoilage – should probably not cause harm, but the best solution will be to discard the entire liquid. How to store wine after opening and what are the optimal conditions for it to age for years?
How to store wine?
The expiration date of wine is not always indicated on the bottles. It is assumed that – when unopened, stored in appropriate conditions, and with no specified aging potential – white wine can last a maximum of 2 years, and red wine up to three. After this time, it may still be drinkable, but the producer cannot guarantee it. How to store wine in an apartment or house to make it better with age?
When answering the question of how to store wine in bottles, several elements should be examined. The first of these is temperature: light and sparkling wines are best kept at around 6-8°C, while red wines can be stored at up to 16°C. The second important aspect is that red wine bottles should be laid horizontally with the corks facing up, but at an angle of about 5 degrees to the ground. This ensures that sediment concentrates at the bottom of the glass. In the case of sparkling wines, the cork should always remain moist, so they must be stored perfectly horizontally. Finally, the best place to store the beverage is free from natural and artificial light to prevent the wine from oxidizing.
Such wine storage in an apartment can be challenging – it's worth utilizing cellars or installing a special refrigerator, for example, on a balcony. Thanks to this, even after a long time, a glass of wine will be exceptionally flavorful!
