1, the nutritional function of wine

Wine is a kind of high-grade beverage containing many nutrients. Moderate drinking can directly affect the human nervous system and improve muscle tension tia. In addition, a variety of amino acids, minerals and vitamins contained in wine can be directly absorbed by the human body. Therefore, wine can play a good role in maintaining and regulating the physiological functions of the human body. Especially for the weak, sleep disorders and the elderly.

Wine contains a variety of inorganic salts, among which potassium can protect myocardium and maintain heart beating; Calcium can soothe the nerves; Magnesium is a protective factor for cardiovascular diseases, and magnesium deficiency is easy to cause coronary atherosclerosis. These three elements are important components of human bones and muscles; Manganese can coagulate blood and synthesize cholesterol and insulin.

2. The special influence of alcohol on women

Women who know red wine often have silky skin. The reason is that what women like best is the magical effect of beauty care.

The beauty beauty anti-aging function of red wine comes from the super antioxidant in the wine, in which SOD can neutralize the free radicals produced by the body, protect cells and organs from oxidation, avoid spots, wrinkles and skin relaxation, and restore the whitening and luster of the skin. Red control people affectionately call it a "drinkable mask".

Another function of red wine-losing weight, each liter of wine contains 525 calories, but these calories are only equivalent to115 of the average daily calories needed by the human body. After drinking, the wine can be directly absorbed and digested by the human body, and it can be completely drunk within 4 hours without gaining weight. Therefore, people who often drink wine can not only supplement the water and various nutrients needed by the human body, but also help to lose weight. The contents of potassium tartrate, potassium sulfate and potassium oxide in red wine are high, which can prevent edema and maintain acid-base balance in the body.

3. Digestive function of wine

After drinking, if there is 60 ml- 100 ml of wine in the stomach, the amount of gastric juice can be increased to 120 ml.

Second, the production method of homemade wine

1. Wash the earthenware jar and disinfect it with boiling water.

2. Put a whole bunch of grapes in cold water, wash them, take them out, and put them in a clean basket to dry them, so that the water on their surfaces will dry.

3. Crush the whole grape, put it in a clay pot, put half of the grapes in the clay pot, pour all the crystal sugar into the pot, and cover the grapes in the pot. Crush the other half of the grapes and put them in an urn. The volume of grapes put into the urn should not exceed eight tenths of the volume of the urn.

4. Cover the jar mouth with clean gauze, and put the pottery jar in a cool and dark place for three days for aerobic fermentation. And put a pair of clean chopsticks into the pottery jar every day for three consecutive days to stir the grapes in the jar, which is beneficial to the aerobic fermentation of grapes. When you stir, you will see many bubbles coming out.

5. After three days, seal the clay pot with water (cover the clay pot and inject clean water along the edge of the pot) for seven days. During these seven days, it is necessary to put a pair of clean chopsticks into the pottery jar and stir the grapes in the jar once a day to facilitate the continuous fermentation of the grapes. In these seven days, you will often hear the water along the urn making a "glug" sound, which is the vent of fermented grapes.

6. After seven days, filter the fermented wine. Scoop out the wine and dregs with a nonmetallic spoon and filter with clean gauze.

7. Put the filtered wine into the bottle and cover it. In the meantime, the wine will continue to ferment, so don't put the wine in a glass bottle, or the gas produced by fermentation will make the glass bottle explode. Put the wine into a plastic bottle and open the lid regularly every day to release the gas produced by fermentation.

8. After seven days, filter the wine again, and then put it in a bottle for sealed collection. You can't drink it for at least a month. The longer the time, the better the taste and the more mellow the wine.

3. What are the hazards of homemade wine?

For those who like homemade wine, there may be many people who don't know the harm of homemade wine. Therefore, the following small series will introduce you to the harm of homemade wine.

1, container selection may lead to poisoning.

We know that many containers are used in the whole brewing process, and the most important one is the fermentation container. There is no doubt that it is safe and reliable to use glass and ceramics as fermentation containers. If stainless steel or even iron containers are used as fermentation containers, it is likely to brew poison.

2. Grape selection may lead to toxicity.

Let's assume that grapes come from orchards. Many growers are likely to use pesticides in the process of grape growth in order to increase the yield of grapes. However, in the process of making wine, we don't advocate cleaning grapes, because we rely on microorganisms on the surface of grapes to guide fermentation.

3. Health problems may lead to toxicity.

In general, the fermentation time of grapes is seven days, which takes a long time. During this period, if infected by bacteria, it will lead to grape rot.

Or your fermentation container is not cleaned, and the container is not clean when stirring, which may lead to bacterial infection. Let's put ourselves in others' shoes. Food will go bad if it is kept for a long time.

4. Other issues

For example, long-term irradiation leads to grape variation; Excessive temperature can also cause mutation of enzymes, and other factors can make homemade wine toxic.

Four, homemade wine matters needing attention

Three taboos

1, the whole production process should not touch raw water, and the grapes should be washed with cold boiled water.

2, the whole production process can't use metal utensils.

3, the whole production process can not be stained with oil.

Pay attention at eight o'clock

1, the frost on the surface of grapes can't be wiped off, because it is a natural yeast, and wine is fermented by this frost.

2, to choose fresh grapes, grapes with a layer of frost on the surface, grapes without frost on the surface are not fresh enough.

3. The wine brewed by darker grapes is darker in color.

The grapes you choose don't have to be too sweet, because rock sugar should be put in the brewing process.

5, the amount of rock sugar can not be too small, because sugar is the best preservative.

6. The wine needs to be filtered twice to make the wine clearer.

7. It is best to choose opaque pottery jars for wine making. If the urn you use is a transparent glass urn, cover it with a black plastic bag when fermenting.

8. Keep wine cans and bottles in a cool place to avoid sunlight.
