In fact, wine is alive, and good wine also has a process from youth, to maturity, to peak, and then to decline in the process of aging. At the beginning, after a series of winemaking processes, such as juicing and maturation in oak barrels, the wine is given a boost by the winemaker, which is like the student stage of human beings. It is then bottled, at which point the wine enters a dormant period, where it needs to be stored in a suitable environment, and then after ageing, the quality is improved a second time.
After ageing, the grapes reach maturity with excellent qualities that continue to be released for a period of time, and finally enter the senescence phase.
The time required for this process will vary depending on the ageing potential of the grapes, with the tannin structure of the wine being the main factor. Wine that has entered the aging period does not mean that it has deteriorated and cannot be drunk, but that the taste and other aspects may be poor, so it is better to set a "shelf life" for wine than a "drinking period" for wine. In this way, everyone thinks that the peak time is the best time to drink, but how to grasp the best time is still a problem.
When you buy some wines, there will be relevant data indicating the most suitable drinking year for the wine, which can be used as a reference. For example, the length of storage depends on the tannin content of the wine, and the more tannins need to be stored for a longer time.
In general, good wine can be stored for 15-25 years, and others are generally not more than 10 years, and the taste may fade after being bottled for a long time.
In fact, you can still drink wine that has passed its expiration date. The expiration date is not indicated on the trademark of foreigners' wines, and there is no concept of expiration date. According to the understanding of the Chinese people, the wine within the shelf life should be clear, not turbid, no precipitation, and the taste effect should be the best.
Wines that have passed their expiration date may experience cloudy precipitation and a decrease in taste quality, but they can still be drunk. Red wines that have been aged for many years, such as dry red wines made from Cabernet Sauvignon and Cabernet Franc grapes, have been aged in new oak barrels for two years, and the taste is hard, bitter and astringent, and must be bottled for about 10 years or more before the taste becomes soft.

When it comes to dealcoholized wines, we can't fail to mention the earliest brand of dealcoholized wines: Bernie. Nowar.
It has been several years since it was launched by Ruihua Juncheng in China. Ruihua Juncheng is a company specializing in imported dealcoholized wines, covering French dealcoholized wines such as Bernie Noir dealcoholized wine series, Australian Bartriti series dealcoholized sparkling wine, Edenwell dealcoholized series, American Ariel dealcoholized series, Spanish Big Red Boat dealcoholization, Phoenix Fort dealcoholization, Aitoshi dealcoholization and so on. Varieties cover all types:
Red wine, white wine, rosé wine, sparkling wine. Due to the downturn in the European wine market, the decline of wine consumption, and the introduction of some policy regulations on car drivers, these constitute a blow to the traditional wine market. Instead, there is an interest in dealcoholized wines that are easier to drink.
Dealcoholized wines, due to their own characteristics: defatting, dealcoholizing, maintaining the complex composition of the wine, gradually occupy the market and are in line with the new trend of popular health foods, while for the French Institute of Agriculture, the production technology of dealcoholized wine is very sophisticated: the alcohol is extracted without affecting the other components of the wine.

Wine can be classified according to the grape variety produced, red grapes, white wines, rosé wines; The amount of sugar in the brewing can be divided into four types: dry, semi-dry, sweet, and semi-sweet. There are also other types depending on the brewing method, such as fortified, ice wine, sparkling wine, noble rot wine, etc.
According to the classification of wine color, it can be divided into:
1) Red wine: The color of the wine is generally purple red, ruby red, garnet red, brick red wine.
2) White wine: wine with yellow-green, straw yellow, lemon yellow or golden yellow in color.
3) Rosé wine: The color of the wine is between red wine and white wine, and it is generally orange-red and pink wine.
Wine in general can be divided into the following four types:
1) Dry: wines with a sugar content of less than or equal to 4g l, or wines with the highest sugar content when the difference between total sugar and total acid (in terms of tartaric acid, the same below) is less than or equal to. This type is sometimes labeled as "SECO".
2) Semi-dry type: the wine with the highest sugar content is generally between 4-12g l, or when the difference between the total sugar and the total acid is less than or equal to. This type is sometimes labeled as "semi-seco".
3) Semi-sweet: wines with a sugar content of no more than 45g l; It is important to note that there is no semi-sweet type of sparkling wine.
4) Sweet: sugar content more than 45g l.
In addition to the above three criteria, wine can also be divided into general wines and wines made in special ways according to the difference in vinification methods, such as icewine made with ice wine, dessert wine made by noble rot infection, and fortified wines made by fortified wine.

Ingredients: grapes, white sugar or rock sugar, appropriate amount of pickled salt (coarse salt) (for soaking), egg white.
1. Wash the grapes and soak them in light salted water.
The right to soak for two hours, this is to remove pesticides and other harmful substances on the grape skin, and do not use it to make wine if it hurts the skin, which will affect the quality of the wine.
2. Rinse again with clean water and drain the water again.
3. Crush the dried grapes and put them in a container; The fermentation process takes about a week (18-25 degrees Celsius), depending on the local temperature, and can be completed in 2-3 days in high temperature areas, until the grape skins are fully floated up and no more bubbles are produced.
4. Stir and add sugar, add the first sugar (5%-7% of the grape weight, and put the second 5%-7% sugar on the fourth day) after 24 hours after crushing, from the first sugar to the end of fermentation on the seventh day, stir once a day in the morning and afternoon, and stir the floating grape skins into the juice again to make the fermentation sufficient.
5. When there are basically no obvious bubbles in the bottle, you can prepare for filtration, which is generally about 8 days; Tie the gauze into a bag, then slowly pour in the wine liquid, then wrap the remaining grape skins and seeds in the gauze, and squeeze the residual juice into the wine liquid.
6. At this time, the wine is a little turbid, seal and stand for a week, add egg white and stir (10 catties of wine a egg white, stir the egg white vigorously, about 15 minutes, stir into foam), can make the wine clearer, let it stand for a period of time, the wine becomes clear and can be drunk.

Ingredients: grapes, sugar or rock sugar, appropriate amount of pickled salt (coarse salt) (for soaking).
Steps: 1. Pick the purple skins as much as possible.
2. Wash the basin and be sure to scald it with boiling water. Connect more than half a basin of tap water in the basin, sprinkle 150 grams of coarse salt (coarse salt without iodine) on each pot of 10 catties of grapes, and soak the grapes for half an hour! Then rinse it again with tap water.
3. On the balcony, lay a clean cardboard to control the dry water of the grapes for drying water droplets, and I directly dried them with a hair dryer.
4. After blow-drying (leaving no apex water droplets, the surface is completely dry) Pick off the grape grains, and crush the grape grains one by one by hand, (really pinch to cramp), sprinkle the sugar and stir evenly after all the crushing, wait for the sugar to completely dissolve, and then put it into a glass jar and seal it. The bottle should not be too full, and there should be a gap to facilitate fermentation! The ratio of white sugar is 10:
2 or 12:2
5. The bottle should not be too full, and there should be a gap to facilitate fermentation! It's best to go stirring once or twice for the first few days of fermentation.
6. This is the eighth day, and there are still fermented bubbles in the bottle up close, continue to ferment!
7. After the fermentation is completed on the tenth day, filter out the grape skin pomace, taste the wine very strongly, drink a small glass and blush after a while, the wine in the jar is sealed and preserved, don't care about it, it will continue to ferment, the longer the wine is, the more mellow and fragrant!
Three Functions of Wine:
1. The nutritional effect of wine.
Wine is a premium beverage with a variety of nutrients. Moderate consumption of wine has a direct effect on the body's nervous system and improves muscle tone. In addition, wine contains a variety of amino acids, minerals and vitamins that can be directly absorbed by the body.
Therefore, wine can play a good role in maintaining and regulating the physiological functions of the human body, especially for the weak, suffering from sleep disorders and the elderly.
2. The special effect of wine on women.
The beauty and anti-aging function of red wine is derived from the super antioxidant content in the wine, in which SOD can neutralize the free radicals produced by the body, protect cells and organs from oxidation, avoid spots, wrinkles, sagging skin, and restore skin whitening and radiance. The red controllers affectionately call it "the ** that can be drunk".
3. Wine aids digestion.
After drinking wine, if there is 60 100ml of wine in the stomach, the amount of gastric juice formation can be increased to 120ml.
Diabetics must pay attention to the following if they drink alcohol:
1. Good blood sugar control, no chronic diseases and diabetes complications of other important organs;
2. No insulin injection and oral sulfonylurea hypoglycemic drugs;
3. Normal liver function;
4. Eat when drinking alcohol to avoid hypoglycemia;

Methods of fermenting wine:
1. Buy grapes:
-
Based on my experience as an intern at a winery, I sincerely recommend that you do not make your own wine for the sake of your health!
As for why, the mobile phone code is too slow, it is recommended to search for "news of blindness by drinking home-brewed wine"!
Let me share with you one more of my experiences:
Fresh things such as vegetables, fruits, and peanuts grown by yourself are certainly good, but once they are fermented and transformed, they are not necessarily!
Therefore, it is recommended that wine, cooking oil, soy sauce vinegar and other things that have been fermented and converted still buy big brands! They will inspect before leaving the factory, and this inspection is not visible to the naked eye! Hope to adopt.
