Why do some wines get better the older they get? Why does wine get more fragrant the older it gets?

As for the wine, the older it gets, the more fragrant it is, in fact, the wine here is not aimed at every wine. If some wine is put more and more, it may taste different, not all wine is and to store, and not all wine is suitable for storage, for example, liquor is very suitable for storage, it belongs to the type that is more and more fragrant.

This principle is not without the ultimate to follow, because in some cases, there may be some substances in the wine, and after a certain period of storage, some of them may produce some fermentation or some chemical reactions, which will make the wine taste more mellow and conducive to people to taste it well.

Because the liquor is stored for too long, chemical changes will occur, mainly oxidation, reduction, esterification and other comprehensive changes. The esters contained in liquor are one of the main flavor components in liquor. The ethanol in the wine is oxidized to acetaldehyde, which is oxidized to acetic acid.

Acetic acid further reacts with alcohol to form ethyl acetate and higher esters. Due to the special aroma of esters, most wines that have been stored for a certain period of time become extraordinarily mellow and reduce the pungency of the wine.

Because the high degree of liquor will become more and more fragrant as it ages, after the liquor is brewed in the natural corner, the whole of the liquor is continuously oxidized into acid, and then the acid reacts with alcohol to produce ethyl acetate with aromatic odor, which can make the liquor mellow and produce the aroma of liquor. Therefore, the longer it ages, the more fragrant it becomes, and the longer the wine, the more delicate and delicious it tastes.

When it comes to wine, we may all think about what is his storage age, that is to say, the longer the age, the more similar it may be, because in the process of long-term fermentation of wine, more things will be emitted, so the longer it is stored, the better it can ferment, of course, this depends on the means of your storage, some people do not store well, so let the air into it, then no matter how long you put it, he will not be disguised, and even will quickly spoil, So I don't have to have a way to store it, so that he can have the conditions for fermentation.

Alcohol can be said to be a very good code change, the role of people also know the role of alcohol, I am very big and long, in fact, it is also a truth, you put the wine and urine there, he can still use some of his own ingredients, let himself spontaneously ferment, that is to say, he himself can send something, and then drive the whole more and more fragrant, so many times when people drink, they will be more concerned about how long the wine is, and they like to drink some older, that is, put it for a long time.

The older the wine, the more fragrant it is, because in the process of aging, the wine will undergo chemical and physical changes, resulting in the increase of the content of aldehydes, ethyl acetate and ethyl formate in the wine, so as to make its taste more mellow.

The reason why the wine gets more fragrant the older it gets.

1. Introduction to the reasons.

In the process of aging, this type of liquor will undergo chemical and physical changes, so that the content of aldehydes in the liquor will increase, while the content of methanol and ethanol will decrease, so that its pungent taste will be reduced, and the taste will be softer and softer.

2. Identification method.

Identification of aged wine can look at the color, cork, aroma and taste of wine, among which the color of the aged wine is yellow, the cork is cork, and the wine aroma is pure and thick and long, the taste is soft and sweet, and the stamina is long, but the color of the new wine is translucent and clear, and the cork is mostly plastic stopper, broken cork, etc., and the taste is spicy and easy to get on the head.

3. Storage method.

In the process of preservation, the aged wine should be placed upright, not tilted, so as not to contact the wine with air, and the storage area of the old wine can not be put perfume, mothballs and other substances with a large smell, otherwise the old wine will be smelled.

Because wine is a fermented product, the longer the mold in it will continue to work, making the wine more mellow, the scientific basis is that there is a special enzyme in the wine, under the prompting of temperature, it will continue to ferment, and it will become fragrant.

Freshly produced wine is not necessarily the best to drink, and needs to be stored for a period of time. During storage, the alcohols in the wine will react with organic acids to produce esters with special aromas, so some wines will be more fragrant after a long time. The esterification reaction in wine is quite slow, and high-quality wine generally needs to be stored for three or four years, or even longer.

However, when the esterification reaction reaches a certain level, it tends to equilibrium and stops. If it continues to be stored, there will also be problems such as a decrease in alcohol content, a weakening of the wine taste, and an increase in the loss of volatile substances.

The older the wine, the more fragrant it is, because in the process of aging, the wine will undergo chemical and physical changes, resulting in the increase of the content of aldehydes, ethyl acetate and ethyl formate in the wine, so as to make its taste more mellow.

The reason why the wine gets more fragrant the older it gets.
