According to The Complete Course of Red Wine published in the United States, 95% of the red wine in the world is best consumed in the year of listing. The remaining 5% red wine depends on what kind of red wine it is. Generally speaking, French ordinary AOC wines can be stored for 5-8 years worldwide, higher AOC wines can be stored for 10- 15 years, and the best top wines can be stored for 20-30 years or even longer. Red wine may taste better after aging, but it may also get worse.
If stored, first of all, red wine should be placed horizontally and protected from light. Temperature 13 degrees, humidity about 75%. It is usually stored in the cellar. Of course, you can buy an electronic wine cabinet if you have no conditions. If not, try to find a dark and shady place, such as wardrobe and under the bed.
How to tell the vintage of wine? Is the longer the wine, the better? Many consumers think that the older the wine, the better, and even take the year as the absolute standard to measure the quality of wine.
Is it true that the older the wine, the better? The insiders believe that there is no necessary connection between the year and the quality of wine. It is not that the older the wine, the better the quality. Because the quality of wine grapes is an important factor to determine the quality of wine. If the temperature, precipitation and other conditions in a certain year are more suitable for grape growth, then the quality of grapes in this year will be good, and the quality of wine brewed from grapes picked in this year will naturally be good. Because the quality of grapes in different years is different, the quality of wine in different years is also very different, unlike what people usually think, the longer the year is marked, the better the quality. The vintage of a wine can only indicate which year the raw materials came from, and it can neither be used as an absolute standard for evaluating the quality of wine nor as a basis for pricing wine. In addition, when storing wine, keep the wine in a cool and insulated place, and the wine bottle must be placed horizontally. Because horizontal placement not only contributes to the precipitation of wine dregs, but also the cork of the wine bottle can be soaked by the wine, and the bottle mouth can be tightly stuffed, which can effectively prevent the wine from deteriorating.
Is red wine as long as possible? No, the storage requirements of red wine are very high. The quality and temperature of wine are very important.
Does the longer the wine, the better it tastes? Not necessarily, the heavier the good wine, the more fragrant it is, and the fake wine will not be drunk for a long time.
The longer the time, the more mellow the wine! It tastes better after drinking! It smells good ~ ~
Excuse me, is the wine as long as possible? It has nothing to do with alcohol content
The storage of wine. Bottled liquor should be placed in a dry, clean, bright and well-ventilated place, and the relative temperature is about 70%. When the temperature is high, the bottle cap is prone to mildew. The ambient temperature of liquor storage shall not exceed 30℃, and fireworks are strictly prohibited. Containers should be tightly sealed to prevent wine from leaking and "spilling".
Liquor is not as long as possible.
"Hundred-year-old wine with ten fragrant flowers" means that after years of aging in Chenfang, the wine is rich, sweet and delicious, which makes it refreshing and has a long aftertaste. In a tomb unearthed in Pingshan County, Hebei Province during the Warring States Period, two bronze hip jars dating back more than 2,000 years have appeared. The wine in a hip flask is emerald green, and its color is clear and transparent, just like the bamboo leaf green wine now; The wine in the other pot is dark green. Such a sweet and wonderful old wine is unparalleled.
Why is Chen Fang's wine more fragrant than the newly brewed wine? To answer this question, we need to know about wine making. Humans knew how to make wine thousands of years ago. Fruit and juice are exposed to the air, and microorganisms convert sugar in juice into alcohol and other substances. Primitive people accidentally drank this fermented juice, which was fragrant and delicious, and began to ferment juice consciously. This was the earliest wine making. According to research, people would brew fruit wine long before there were words.
Our country's wine is world-famous. Famous wines are mostly made of sorghum, wheat and peas, among which malt or bran koji is used as saccharifying agent of starch, and maltose after fermentation becomes alcohol under the action of yeast. But the alcohol content of this wine is very low. After distillation, you get high-content liquor.
Alcohol is very different from the white wine we drink. Pure alcohol aqueous solution is almost tasteless, while ordinary liquor has a unique fragrance, taste and color. This is because liquor contains not only alcohol, but also sugars, glycerol, amino acids, organic esters and vitamins.
Fruit contains a lot of sugar, so it can also be used to make wine. Red and purple grapes, golden and pleasing oranges, red apples in the green and good lychees in Lingnan can all be used to make wine.
Whether it is fruit wine or white wine, ethyl acetate is the hero who can emit aromatic smell. However, the content of ethyl acetate in new wine is very small. The aldehydes and acids in wine not only have no fragrance, but also have the function of moistening the throat. Therefore, the newly brewed wine tastes raw, bitter and astringent, and it takes several months to several years of natural aging to eliminate the odor and give off a strong bouquet. The working people in our country have gradually mastered the experience of aging wine in the long-term brewing process. They put the newly brewed wine in a jar and sealed it, and stored it in a place with suitable temperature and humidity for a long time, so that it slowly changed chemically, and the aldehyde in the wine was continuously oxidized into carboxylic acid; Carboxylic acid reacts with alcohol to produce ethyl acetate with aromatic smell, which makes the wine mellow. This change process is the aging of wine. However, this chemical change is very slow and takes a long time, and the aging of some famous wines often takes decades.
Maybe you think the older the wine, the better, right? This is not entirely correct. The aging of wine must meet certain conditions to increase the amount of ethyl acetate. If the jar is not sealed or the sealing condition is not good, and the temperature and humidity conditions are improper, not only will the alcohol run away after a long time, but it will also turn sour and sour into vinegar. This is because there are acetic acid bacteria in the air. When wine comes into contact with air, acetic acid bacteria will take the opportunity to enter the wine. Under the action of acetic acid bacteria, alcohol will undergo chemical changes and become acetic acid. Especially beer and fruit wine are more prone to rancidity and vinegar.
Maotai, xifeng liquor and Fenjiu are different. Because the content of alcohol in soju is about 50%, alcohol with this concentration has bactericidal effect, and acetic acid bacteria cannot survive and reproduce in soju, so alcohol will not become acetic acid.
So we can say that the older the wine, the better. The development of modern science and technology has greatly shortened the aging time of wine. If the new wine is irradiated and tasted after 15 days, the aroma, glycol and aftertaste of the wine will be improved and the miscellaneous taste will be reduced. Chemical analysis shows that the content of ethyl acetate is greatly improved, and the rich wine aroma can be comparable to that of natural aging. Radiation method can effectively shorten the storage period of wine and is a scientific method for aging new wine. Recently, a new type of wine aging device made by scientists using electronic comprehensive technology has advanced level in the world and is very suitable for aging high-quality wine and fruit wine. All kinds of new wines can be aged for six months to one year as long as they stay in it for eight to ten minutes. Thereby saving a lot of warehouses, containers and funds, and making contributions to the development of the wine industry.
Is red wine as long as possible? No, red wine has an optimal drinking period, after which the taste is not so good.
Is red wine as long as possible? Red wine storage
Temperature. The optimum storage temperature of wine should be about 65438 03℃. It is best to keep the temperature constant, otherwise it will do great harm to the quality of wine. With the increase of temperature, the time required for wine to mature will be shortened, the flavor of wine will become rough, and wine may deteriorate due to excessive oxidation.
Humidity. Humidity mainly affects cork, and the humidity is generally 60%-70%. If the humidity is too low, the cork will dry, which will affect the sealing effect, let more air contact with the wine, accelerate the oxidation of the wine, and lead to the decline of the quality of the wine. Of course, too high humidity is not good, and moldy cork will also destroy the quality of wine.
Light. Ultraviolet rays in the light are also very harmful to wine, which is also one of the chief culprits to accelerate the oxidation process of wine. Therefore, if you want to store wine for a long time, you must keep it in a dark place. Wine is in a bottle, and its change is a slow process. Vibration will accelerate the ripening of wine, and of course, the result will also make the wine rough. So stay away from the vibration and don't move frequently.
Location. Everyone knows that wine should be placed horizontally. In fact, you can also tilt the bottle mouth upwards 15 degrees. For red wine that needs to be stored for a long time, it is not advisable to put the bottle mouth down. Because wine will precipitate when it is stored for a long time, it will gather at the bottom of the bottle when it is laid flat or the bottle mouth is slightly tilted upward; If the bottle mouth is inclined downward, the sediment will gather in the bottle mouth and stick there for a long time. When pouring wine, it will be poured into the cup with the sediment, which will affect the taste of the wine.
Isn't it better to brew your own wine as long as possible? The longer you brew your own wine, the better.
In the later stage of fermentation, the wine was not bubbled (produced gas), which indicated that the fermentation was over and the wine could be filtered, bottled and preserved.
The longer the wine, the better. Red wine is no better. Red wine storage has certain environmental factors. There are many famous pits abroad, and those wineries have strict temperature and humidity control. Only when stored at a certain temperature and humidity will they taste good. Good red wine is very sensitive to temperature. If you touch the glass wall when drinking red wine, it may change the taste of the wine. This is why red wine is usually drunk in a goblet. ...
