Why should the wine be left for half an hour or an hour after opening?

When you drink red wine, why do you want to leave it for half an hour or an hour? That's what we call decanting, so what does it mean? After reading it, let you know more about wine!

Our Chinese wine culture is very long, many people like to drink, and there are many varieties of wine, such as the beer we often drink, etc. Other wines are drunk straight after the bottle is opened, but red wine is different. Before drinking red wine, it is usually necessary to sober up, which usually takes 20 minutes to 2 hours.

So what does it really mean to be sober? Red wine is a type of wine, which is a fruit wine made by natural fermentation. Red wine is made from grapes, and the skins and seeds are not removed during the vinification process.

As a result, there are many tannins and tannins in wine, which can affect the taste of red wine. The process of decanting is to allow the wine to come into contact with the air as much as possible, remove some of the tannins, and improve the taste of the wine through oxygen oxidation.

Because red wine is usually laid flat or inclined at 30 degrees. Over time, there will be sediment, residue of oak cork, etc。I opened the wine and drank it.

These impurities can make the wine cloudy and affect the taste, so it is necessary to precipitate the impurities and sink them to the bottom. Even some red wines need to be filtered with filter paper. Shake the wine so much that it evaporates the foreign flavors, methanol, and other foreign flavors that were originally sealed in the wine.

Let the aromas of the wine unleash and further improve the taste of the red wine. This is actually very important and should be the main purpose for placing the decanting. <>

Everyone knows the importance of tannins to the taste of red wine. The purpose of pouring red wine is to contact the air to soften the tannins and improve the quality and taste of the wine. <>

Traditional red wine in life has matured for a period of time after brewing, and generally only needs to open the bottle cap two hours in advance to achieve the purpose of decanting; For a new good wine, the tannins taste very strong, so it can be poured out with a decanter, decanted for two hours, then poured into the original bottle, sealed and stored for a period of time, and then decanted again with a decanter, which only takes an hour, while old red wine does not need to be decanted. If it has an astringent taste, it can be removed by shaking it in a glass a few times.

After opening the bottle, it should be left for half an hour or an hour, the main reason is that you can sober up the wine, so that the red wine you drink should have a more pure taste and taste.

Half an hour or an hour after opening the bottle is used to decant the wine, which may cause the carbon dioxide in the wine to disappear.

Red wine is made from grapes, and it is left for a period of time after opening the bottle to allow the wine to be more fully oxidized with the air, so that it will taste better.

Because red wine needs to be decanted after opening, it will be sweet and mellow after decanting.

Summary. Red wine is largely cut off from the outside air until it is opened. After the bottle is opened, the oxygen in the air can actively escape to the red wine, and the oxygen reacts with the phenolic substances in the red wine to produce hydrogen peroxide.

The vast majority of red wines can be resealed and refrigerated in the refrigerator for about 3 days after opening. But in reality, it still depends on the specific situation. Generally speaking, the higher the acidity, tannins, and alcohol content of red wine, the more resistant it is.

In general, red wine should be corked after opening, placed in a cool and dark place or in the refrigerator compartment upright, and drunk within 3-5 days.

Red wine is largely cut off from the outside air until it is opened. After the bottle is opened, the oxygen in the air can actively escape to the red wine, and the oxygen reacts with the phenolic substances in the red wine to produce hydrogen peroxide.

Red wine can be stored for about a week after opening, and generally after the red wine is opened, it is sealed and put in the refrigerator, which can be stored for about a week without tasting and about 3 days at room temperature.

If it takes a long time, the oxidation reaction will begin to occur after the red wine is opened, and if the time is too long, the red wine will be over-oxidized, and the taste will become sour, which is not suitable for drinking. Wine can be preserved by adding a plastic bag to the wine bottle to prevent the smell in the refrigerator from affecting the flavor of the wine. The refrigeration temperature in the refrigerator can affect the flavor of the wine to some extent.

How to store red wine:

1. Refrigerate. A well-sealed, near-full bottle of wine can be stored in the refrigerator for a considerable amount of time if stored properly. In general, red wine is stored longer than white wine. A bottle of medium-sized winery can be kept for a week or more.

However, refrigerated wines should be allowed to warm to room temperature before drinking.

2. Change the bottle. If you have unfinished wine, you can pour it into a small bottle to store it, which can reduce the contact surface between the wine and the air. A bottle of wine can usually last for years if it is full of wine and with a fresh and clean cork. However, it is important to note that small bottles should not be washed with dish soap or detergent to avoid leaving residues that can contaminate the wine.

3. Vacuum pump.

The air in the bottle is removed and sealed with a special plastic stopper and an air extraction rod to extend the "life" of the wine by up to 2 weeks. It is best to keep the deflated wine in the refrigerator, and when you drink it again, take it out of the refrigerator and let it rise to a suitable temperature before enjoying it.

Opened red wine can be stored for about 1 to 3 days, not for a long time, because long-term storage may lead to the growth of bacteria or moldy bacteria, and may even affect the taste of the wine. In daily life, you can drink some red wine appropriately, which can achieve the effect of promoting the body's metabolism, but you can't drink too much, because the alcohol content in the wine is relatively high. If the wine is stored at room temperature, it can generally be stored for 1 to 3 days, and if it is stored in the refrigerator, it can be stored for about 1 week.

If the time is too long, it may affect the taste, so after the red wine is opened, it is recommended to drink it as soon as possible for the old man.

Summary. How long can red wine be stored after opening.

Can you add, I don't quite understand it.

After the red wine is opened, it will begin to oxidize quickly, generally about 3 days, it can be completely oxidized, and then it will be over-oxidized and the wine will become sour, and the sour red wine is not suitable for continued drinking. Wine is a living drink that changes over time. The cork keeps the wine sealed in the bottle, creating an airtight space that preserves the wine with little or no oxygen.

However, when you open the cork, the air reaches the wine and immediately begins to deteriorate.
