The supply capacity of the same large vineyard is fixed. If more vines are planted, more wine will be produced, but the quality of the wine can not be guaranteed.

Only low yield can ensure the high quality of the planted grapes and make the grapes more rich in flavor. Therefore, many producers of high-quality wines have given up high production and turned to produce high-quality wines with low production. Cheap wine is mass-produced wine, and more mechanical operations are used; However, the output of expensive wine will be low, and more manpower will be used, and pure manual brewing will be adopted.

2, the difference between grapes:

The quality of grapes is also the main factor affecting the price of wine, and many wines with lower prices have lower requirements on the quality of grapes. As long as the grapes are not spoiled, they can be used to make wine. The requirements for expensive wines are relatively high, and the grapes with poor maturity are not acceptable! The vines are less than 30 years old, and the grapes are picked mechanically. No! The quality of grapes is also an important factor in determining the price.

3, the difference between the year:

Cheap wine has little aging potential. 3-4 years after grape picking is the best drinking period. If it passes the suitable drinking period, although it can still be drunk, its taste is not so good.

If the drinking period 10 years has passed, you should be careful. Your wine is probably grape vinegar. The best drinking period of high-priced wines is basically after 10 years. When cheap wines become vinegar, expensive wines are just the right time to drink.

4. Functional differences:

Cheap wine is suitable for daily drinking at ordinary times. When you drink it yourself or drink a glass of wine with your family, it is relaxed and comfortable, and the quality requirements for wine are not very high. However, there are many rules for expensive wines. Generally, these drinks will be shared with friends, relatives and professional drinkers on special days or occasions.

5. Style differences:

Cheap wine is simple and easy to drink, like a simple girl, not so complicated, so that you can appreciate the charm of simple wine. And expensive wine, like a mature and intellectual woman, you need to get in touch with it slowly to appreciate the breathtaking charm. Therefore, expensive wine is more suitable for tasting, while cheap wine is more suitable for ordinary drinking.

The benefits of drinking red wine:

1, prevention and treatment of colds

Up to now, there is no good strategy for influenza in the world, because the virus of influenza is resistant to most drugs. However, it has been found that people who often drink wine rarely catch a cold.

This phenomenon attracted attention, and they added red and white wine and grape juice to the virus culture solution for experiments. The results showed that common cold viruses such as herpes simplex virus and Coxsackie virus could lose their vitality in wine and juice, and the juice extracted from grape skin was the best.

Scientists believe that this is because grapes contain "phenol" compounds, which can form a thin film on the virus surface, making it difficult to enter human cells, thus achieving the effect of preventing and treating colds. Because "phenol" mainly exists in grape skins, drinking hot red wine can alleviate cold symptoms and prevent colds when you have a cold.

2, help to improve memory

The experimental results published by scientists show that drinking wine in moderation is helpful to improve brain memory and learning ability. After a lot of experiments, two doctors from the University of Milan found that drinking wine in moderation will promote the production of a certain amount of chemicals in the brain, which can promote the production of a kind of memory related to nerve cells.

According to the measurement, after drinking wine, the generation of this kind of wine enhances the memory and learning ability of the brain compared with those who don't drink it. Another doctor found that obese patients who drink wine properly during weight loss will maintain vigorous energy and will not be depressed because of dieting, which will lead to memory loss.

3, delay aging

Like metal, the human body will gradually "oxidize" in nature. The culprit of human oxidation is not oxygen, but oxygen free radical, which is an active gene with unpaired electrons outside the nucleus.

This unpaired electron can easily cause chemical reactions, damage important biomolecules such as dna (deoxyribonucleic acid), protein and lipid, and then affect the cell membrane transport process, damage the functions of various tissues and organs, and promote the aging of the body.

Red wine contains many antioxidants, such as phenolics, tannins, flavonoids, vitamin C, vitamin E, trace elements such as selenium, zinc and manganese, which can eliminate or fight against oxygen free radicals, so it has the function of anti-aging and disease prevention.

4. beauty beauty's role

Since ancient times, red wine, as a good product in beauty beauty, has been loved by people. Some people say that French women's skin is delicate, moist and elastic, which is related to frequent drinking of red wine.

Red wine can prevent aging and make skin wrinkle less. In addition to drinking, many people like to apply red wine on their faces and body surfaces, because low concentration of fruit acid has the function of anti-wrinkle and skin cleaning. Although there are many benefits of drinking red wine, there are limits to the quantity. Experts believe that drinking red wine should not exceed 250 ml per day according to the alcohol content 12%, otherwise it will be harmful to health.

5. Prevent cancer

Red wine is made from grapes, and resveratrol contained in grape skins has the best anticancer performance among hundreds of plants that people often eat. It can prevent normal cells from becoming cancerous and inhibit the spread of cancer cells. Among all kinds of wines, the content of resveratrol in red wine is the highest. Because resveratrol can make cancer cells lose their activity, red wine is a good product to prevent cancer.

6, inhibit fat absorption

Japanese scientists found that red wine can inhibit fat absorption, and some mice did experiments. After drinking wine for a period of time, mice found that the absorption of fat in their intestines slowed down, and clinical trials on people also reached the same conclusion.

7. Prevention of breast cancer

The latest experimental results show that wine has a strong inhibitory effect on cancer by feeding mice with induced cancer. Researchers at Illinois Pharmaceutical University in the United States chose mulberry, peanut and grape skin-the strongest anti-cancer activity.

Scientists in the United States have recently discovered that wine contains a chemical substance that can prevent breast cancer. roy Wilhemlms of the San Francisco Wine Research Institute said at a press conference in Washington that they found a substance that can prevent breast cancer in red wine and white wine. This substance has this effect because it can resist estrogen, which is related to breast cancer.

8. Prevention and treatment of cardiovascular diseases

The proanthocyanidins in wine can stabilize the collagen fibers forming various membranes, reduce the permeability of blood vessel walls and prevent arteriosclerosis. In addition, the risk of death from proanthocyanidins infarction. According to the statistics of the American Medical Research Association, French and Italians who like to drink low-alcohol wine have the lowest heart disease mortality, while Americans and Finns who drink more alcohol and less wine have a high heart disease mortality.
