According to experts, wine needs to be stored in a cool, dark environment. But why is that? And what happens if this rule is not followed?
Except for a few milligrams of sulfur, wine does not contain preservatives, yet it can be kept for years, sometimes decades, without deteriorating. Indeed, storing wine for a long time can even improve its quality! But this cannot be generalized, as hundred-year-old wines are usually quite rare. Over time, most of the wines produced for daily consumption retain their characteristics but do not improve in time.
However, there is a rule that always applies : the lower the storage temperature, the slower the aging of the wine. In fact, wine is a living product and to be enjoyed it always needs the best conditions of temperature and organic stability.
What does it mean? For example, if the temperature of a red wine increases too much, the alcohol will become predominant, if you lower the temperature of the same wine too much, the tannins will become sharp. In short, as well as it happens with its service, the preservation of wine has its own logic.
Here is a brief guide on how to best preserve wine and keep all the organoleptic characteristics intact.
Sparkling wine and prosecco
Sparkling wine and prosecco can be kept in the fridge for a maximum of two days. It will be necessary to close the bottle well with special caps for sparkling wines, to prevent the excessive degassing of the product.
Red wine does not go in the fridge, but it needs to be stored in a cool place with a temperature that ranges from 10 to 12 C°. The fridge tends to distort the quality of the product because once the red wine has been opened, seldom does it tolerate another change in temperature. Sometimes leaving it to mature in the bottle after a day or two can create pleasant surprises.
Still white wines
Unlike red wine, white wine must be kept in the fridge, especially if it is a simple and not particularly structured wine. But, if it is a complex white wine, it needs to be kept at a cool temperature, ranging from 10 to 12 C°.
As with red wine, the 4 – 6 C° of the fridge could alter the balance of a structured white wine.
It is always preferable to keep sweet wines in the refrigerator, even if they are placed in the least cold part of it. Raisin wines with a high glycerine degree and highly structured should be stored at a slightly higher temperature (10 – 12 °). On the other hand, it is not worth leaving them at room temperature for too long as oxidation could alter their organoleptic dimension in a negative way.
