The composition of red wine is quite complicated, with water accounting for more than 80%, followed by alcohol, generally 10% to 13%, and the remaining substances exceeding 1000, and more importantly, more than 300 minutes. Other important components of red wine, such as wine acid, fruit, minerals and tannic acid. Although the proportion of these substances is not high, they are the decisive factors of wine quality. Good quality and good taste of red wine is because they can present a balance of organizational structure, which makes people enjoy the taste endlessly.
Technical terms related to red wine
Wake up
Because red wine is considered as a living liquid and contains tannic acid, the changes of tannic acid after contact with air are very rich. The best way to tell the change of a bottle of wine is to pour two glasses for the first time after opening the bottle, drink one glass first, and then drink another glass until it is finished, so that you can clearly feel it. The wine changing time of each bottle is different, maybe 10 minute, maybe half an hour, maybe two hours later. How to discover the vitality of wine depends on your own feelings and experiences.
"downgrade"
The way to drink is to pour the wine into an eccentric shape, which is called drinking, but what is the purpose of drinking?
In fact, there are two ways, one is to remove the sediment that has been left for many years. Although these sediments are harmless to drink, they are harmful to the flavor of wine and must be removed.
The other is to awaken the original flavor of wine with less years from deep sleep. Because the cocktail party has the opportunity to contact with the air because of the drinking action, the sleeping wine will be mellow immediately.
"wine label"
How to choose a good bottle of red wine, the first requirement is smooth taste, what kind of taste is smoother, depending on personal preferences, tasting red wine is a very profound knowledge, learning wine tasting takes a long time of research and tempering, and learning to recognize wine is a relatively simple matter.
How to identify wine? Learn to read the label on the bottle first. The label of wine is also called "etiquette" (French, meaning license), just like a resume. Just as there is a saying among people who know wine, "Just look at the label to know its taste", the label does reveal information about the taste (characteristics) of wine.
Generally, the label will indicate: grape harvest year, wine name (named after the place of origin or winery), place of origin or place of origin, place name of manor, name of producer (winemaker), capacity, alcohol concentration, etc. According to the designer's design, there are various styles of labels, so the data is written in different locations.
The weather in the harvest year will affect the quality of grape harvest.

Storage of red wine
The most taboo to preserve wine is the strong change of temperature. If you bought it at a store at room temperature, just leave it at home at room temperature. If you want to drink chilled wine, just freeze it before drinking it. If the wine is stored in the refrigerator, it is only suitable to be stored in a vegetable room with small temperature change. The most ideal and long-term storage environment is that the temperature is about 12~ 14 degrees Celsius, the humidity is about 65%~80%, and the bartender is in the basement. Keep it clean to prevent other smells from penetrating into the wine.
cork
Cork has the characteristics of low density, good elasticity, strong flexibility, air tightness, corrosion resistance, decomposition resistance and difficult deterioration, which can keep the quality of wine unchanged over the years. Usually, the length of cork used in general grade wine is about 3.5 cm to 5 cm, and the length of cork used in better quality wine is more than 5 cm. High-quality wine usually uses long cork, but long cork wine can not guarantee high-quality wine.
room temperature
We often hear that a certain wine is most suitable for "drinking at room temperature". What does room temperature mean? In fact, room temperature usually refers to the temperature in the country of origin, not the room temperature in China. For French wines, room temperature usually refers to 16 to 18 degrees Celsius. For China, which has a vast territory, except for the cold winter, most of this temperature needs to be achieved by refrigeration. Never put the shower at room temperature and take it for granted that it is "room temperature".
Selection of tasting cup
Only by choosing the right tasting cup can we taste the wine completely. Tulip-shaped or neck-necked transparent wine glasses are the best ones used in wine tasting, which can concentrate the aroma of wine near the mouth of the glass and make it easy to judge the smell. Don't have carvings or other colors, so as not to misjudge the color of the wine.
Wine doesn't get better with age.
The older the wine, the better it smells. After the peak of wine aging, it will only go from bad to worse, just like a beautiful woman has her twilight years, and then she will gradually get old and enter a degenerate period. Therefore, wine also needs to be drunk at the right time to taste its peak flavor.
Store your favorite wine.
Find a cool and quiet corner as a place to store wine to avoid strong or abnormal smells (such as paint smell and durian smell) and excessive temperature affecting wine; Don't be too addicted, always take it out and enjoy wiping. The last thing wine needs is shaking and light stimulation.
Long-term storage, lying down is better
If you want to store wine for a period of time, it is best to keep the bottle flat so that the cork can contact with the wine liquid and keep it moist. If the bottle is placed upright, the cork will be excessively dry, which will let air in and destroy the quality of the wine.
How to deal with endless wine?
Drinking red wine is good for health, which makes many families buy red wine and drink it slowly at home. But at present, most of the red wine on the market is 750 ml, and a person can hardly drink a bottle of red wine a day. As soon as the cork of red wine is opened, it begins to oxidize when it comes into contact with air. Endless red wine is like chicken ribs. It is tasteless to eat and a pity to throw it away. What should I do with the endless red wine?
In fact, endless red wine can be stored in small bottles, because the more wine in the bottle, the less air, the slower oxidation and the longer storage time. In addition, the air extractor or nitrogen bottle sold in the market can be used, and the storage period of red wine can be extended by 3~5 days or even a week. If no utensils are available, you can also replace the original cork and put it back in the refrigerator (the lower the temperature, the slower the aging). The wine bottle should be upright to reduce the contact area between the red wine and the air in the bottle. Despite these treatments, I suggest you finish them as soon as possible.
The remaining red wine can also be used for cooking or adding other drinks to make cocktails; Taking a red wine bath is also a good way to keep fit.
