Can you still drink red wine after a long time, can you still drink red wine after a long time?

If it's too long, you can't drink it.

If the red wine is to be left open for a long time, be sure to cover it with a cork, and it is best to put a layer of sealing wax on the edge of the cork to prevent contact with the air, and it can be stored in the refrigerator. If the red wine is not sealed well after opening, the shelf life is about 10 days, and if it is longer, it is best not to drink it.

Redwine is a type of wine and does not necessarily refer to red wine specifically. The composition of red wine is quite simple, it is a fruit wine made by natural fermentation, and the most important thing is grape juice, and there are many ways to classify wine. In terms of the color of the finished product, it can be divided into three categories: red wine, white wine and pink wine.

Among them, red wine can be subdivided into dry red wine, semi-dry red wine, semi-sweet red wine and sweet red wine, and white wine can be subdivided into dry white wine, semi-dry white wine, semi-sweet white wine and sweet white wine. Pink wine is also called rosé wine and rosé wine. The bayberry made is called bayberry red wine.

You can't drink expired red wine, and it is not recommended to drink expired red wine. Generally speaking, the only type of bottled red wine that has a shelf life of 10 years is not allowed to be drunk. Red wine will be very bad on the taste, and the taste of such red wine will generally become very bland, even sour, a bit like soy sauce.

If it is stored for a certain period of time, cloudy precipitation may occur, and the taste of the red wine will deteriorate. If it is left for too long, the red wine will have a rancid smell, and even foam floating, giving off a strange taste, such a red wine cannot be drunk. Most of the red wines have a drinking period of 1 2 years, and a very small number of wines have a drinking period of more than 10 years, and some red wines can be stored for a long time if the method is appropriate.

The polyacid content in red wine is very high, so drinking red wine often has a very good effect on the prevention of cardiovascular diseases. Not only that, red wine can also increase appetite, red wine contains amino acids, sugar, vitamins and other nutrients needed by the human body. Therefore, drinking red wine appropriately during the expiration date is not only enjoyable, but also beneficial to the body.

For your question, you can't just talk about it, please refer to the following precautions before deciding whether to drink or not.

1. Storage of red wine.

1. The storage of red wine requires a suitable temperature, the theoretical temperature is about 12, 7 18 can be.

2. The seal of the bottle cap should be good, and it is required to protect it from light, because ultraviolet rays will make the wine mature early and deteriorate.

3. Avoid vibration, place it horizontally, keep the cork moist to prevent air from entering, and avoid being too humid to prevent bacteria from breeding.

2. The storage time of red wine.

Red wine is not always better the older it is. The vintage on the wine refers to the grapes of the year. The majority (99%) of wines are not ageable and the best drinking period varies depending on the wine, but is generally between 2 and 10 years.

Only a small number of particularly good wines have the ability to age. Some of the top French and Italian wines have been aged for decades or even centuries. Many of the wines from Bordeaux's top châteaux are still drinkable even if they have been preserved for more than one century.

Wines require tannins (i.e. tannic acids) for ageing, and Cabernet Sauvignon (grape variety) is the most suitable for ageing due to its geography and characteristics.

Red wine that has not passed its expiration date can be drunk, but the flavor of red wine that is close to its expiration date may not be good.

The shelf life of general red wine at room temperature is five years, if some wine is not suitable for aging, it will be wasted, and the top red wine is generally stored in the cellar for as long as possible, but if it is Australian and Chilean red wine, it is necessary to drink it while the year is new, and the general family conditions do not have the conditions of the wine cellar in terms of wine storage, so it is not recommended to store the old red wine at home.

In addition, if the red wine is opened and cannot be drunk, it should be drunk within two or three days, if the red wine cannot be drunk, the quality will change, and such red wine must be placed in the fresh-keeping cabinet when preserved, so that it can be stored for a little longer.

Pay attention to the following points for the preservation of red wine:

1. Do not put it outdoors, taboo in winter.

Leaving it outdoors for too long is not only prone to bursting, but also damage the wine, which directly damages the taste of the wine. Because when the freezing point temperature of the wine is reached, the wine is prone to precipitation of tartaric acid and tannins, which will only slightly affect the taste. However, a small amount of ice residue in the wine will not destroy the aromatic substances of the wine, and you only need to wait for the ice cubes to melt and let it stand for a week or two before drinking.

2. Keep away from radiators and floor heating to prevent plugging.

If you want to continue to store wine at room temperature, be sure to keep it away from heat sources and never leave it near radiators. In an environment of more than 30°C, the heat expansion and contraction will cause "congestion" in one day, which will destroy the quality of the sake.

3. Do not place it in the basement, be careful of the smell.

It is not recommended to put it in the basement not only because the basement is cold, but also because the cork of the red wine itself is permeable, and the basement in the north often stores radish and Chinese cabbage, and the wine is placed with vegetables for a long time, and the vegetable flavor will soak into the wine through the gap in the cork, thus affecting the flavor of the wine.

Generally speaking, it is best to drink red wine on the same day when it is opened, and it is best to drink it within 3 days if you can't finish it. Red wine needs the right amount of oxygen to improve the taste after opening, but long-term oxidation, and will destroy the flavor and texture, how long can red wine be stored after opening, depending on a variety of factors, the higher the tannin content in the wine, the longer the storage time after opening, generally speaking, red wine can be stored for about 3 days.

There should be no problem with putting it in the refrigerator, so if you put it outside, you can't drink it for two days, so I think it should be kept in the refrigerator, but if there is a stopper, the storage time is also relatively long, so this is still a case-by-case analysis, I think it is better to drink it as early as possible, so that it will not affect its taste, because the taste may change a lot after a long time, so basically you can drink it as soon as possible.

Red wine can still be drunk after a long time, and it is not recommended to drink it beyond the expiration date.

Each wine has its own shelf life, most of the wines on the market have a shelf life of 2-3 years, and the more advanced wines can be stored for 8-10 years if stored properly. After opening, the wine needs to be drunk as soon as possible because the oxygen has entered the wine, and it cannot be stored for too long, otherwise it will deteriorate.

Wine storage tips

Wine storage temperature: The quality and aging of wine is greatly affected by temperature, and it is generally believed that 10-15 is the optimal range, and the wine will be better aged, and the lower the temperature, the slower the aging rate. The chemistry in the wine doubles every 8 years.

Many times the wine taken out of the refrigerator will be too cold, lacking aroma and sour, especially on white wines.

Wine storage humidity: An environment with a humidity of 70% is an ideal environment for wine storage. If the humidity in the environment is too low, the cork will lose its elasticity, causing oxygen to enter the bottle and come into contact with the wine, accelerating the oxidation and aging process of the wine.
