Judging the quality of a bottle of wine can be based on the smell of the wine, its color, transparency, and its vintage. The color and vintage are easy to understand, but how to distinguish the smell? Is it the usual aroma of wine? The following are six tips that may help those who need them.

To teach you how to judge the wine

First, observe the appearance of the bottle

Each wine has its own label, the label is rich in information, can help us judge the wine's source, origin, vintage, grade, and even taste.

Is the cap on the wine bottle different? An unopened wine with a protruding cork or mucus at the mouth of the bottle indicates that something is wrong with the quality of the wine. Some French wines have the icon of a woman's head printed on the lead seal of the bottle, which proves that it is an authentic original wine after being taxed in France.

Is there a Chinese logo on the back of the bottle? All imported food should be added Chinese back label, if there is no Chinese back label, it may be smuggled imports, the quality can not be guaranteed. From the back of the bottle label on the international bar code can be judged from the country of origin, such as: 3-French origin, 6-Made in China, 8-Italian origin, 9-Australian origin.

There is also information on the bottom of the wine bottle. If it is imported from a country such as France, the unit of measurement on the bottom of the bottle is 75cl, not 750ml, and there is no such unit of measurement as "ml" in France. Wine bottles have a hump at the bottom, which is where the dregs of the wine are deposited when the wine is standing upright. The longer the wine is stored, the deeper the hump. So, in general, good wines need to be stored for a long time, the bottom of the bottle is deeper, but the wine with a deeper concavity is not necessarily a good wine.

Secondly, observe the body of the wine

Is the color of the wine unnatural? Usually the color of the wine is ruby red, or light gold, rosé and other clear natural wine color, the body of the wine after deterioration will have a sense of turbidity, if the color is not natural, there will be the suspicion of collusion.

Whether the wine body has an unknown suspension, if it is the bottom of the bottle a little precipitation is normal crystallization.

Third, pay attention to the cork logo

Open the bottle, see if the cork text is the same as the text on the bottle label. In France, both the bottle and the cork are specialized.

Fourth, smell the wine

Usually when you open a bottle of wine, you will smell the aroma of the wine, if the wine has a choking smell like nail polish or acetic acid, it means the wine has gone bad.

Fifth, observe the wine hanging cup

Pour the wine into a red wine glass, gently shake it, and observe whether the wine body has a hanging cup phenomenon, if the wine body can not be hung, indicating that there is a possibility of wine blending. Normal wine liquid hangs on the wall of the glass, a uniform circle, like a "small skirt", uniform, detailed.

Sixth, directly taste the wine

Drink the first mouthful of wine, wine through the throat, normal wine is smooth, such as a strong sense of stimulation, or residual odor in the mouth of the smell of chemical odors or bad smell, is not normal.

Wine Effects and Roles

Wine is warm and sweet, and enters the liver, spleen and heart. Beneficial cardiovascular, skin care, anti-cancer and anti-tumor, anti-degeneration and anti-radiation, enhance appetite, excitement and strong, eliminate fatigue, stop bleeding and diuretic effect. Mainly used for treating loss of appetite, weakness of hands and feet, mental sleepiness, insomnia, dysuria.

① "Materia Medica": "Wine warms the waist and kidneys in the color."

② "Drinking food recipe": "Wine luck line stagnation, so that all the veins smooth."

Tonic

Wine contains sugar, amino acids, vitamins, minerals. These are essential nutrients for the body. It can be absorbed directly by the body without pre-digestion. Phenolic substances and OligoeLement (OligoeLement) in wine, which functions as a high oxidizing agent, can prevent the reactive oxygen (Ros) produced during human metabolism from . . damage (e.g. to DNA and RNA in cells), which are among the factors leading to some degenerative diseases such as cataracts, cardiovascular disease, atherosclerosis, and aging. Therefore, regular consumption of moderate amounts of wine has the effect of preventing aging and prolonging life.

Digestive

The best beverage to accompany meals. Wine can stimulate gastric acid secretion of gastric juice, wine tannin substances, can increase the intestinal muscular system in the contraction of smooth muscle fibers, adjusting the function of the colon, colitis has a certain effect. Sweet white wine contains sorbitol, which helps digestion and prevents constipation.

Bactericidal effect

A long time ago, people recognized the bactericidal effect of wine. For example: colds are a common disease, the antibacterial substances in wine have an inhibitory effect on the influenza virus, the traditional method is to drink a cup of hot white snow champagne or a cup of red wine heated, beat an egg, stirring, that is, to stop the heating, a little cooler after drinking. Studies have shown that the bactericidal effect of wine is due to the fact that it contains antibacterial and antiseptic substances.

Diuretic

Some white wine, potassium tartrate, potassium sulfate, potassium oxide content of the high school, with a diuretic effect, can prevent edema and maintain the body acid-base balance.

Delaying the aging process

The human body, like metals, will gradually oxidize in nature. The main culprit of human oxidation is not oxygen, but oxygen free radicals, a cell nucleus containing unpaired electrons outside the active group. This unpaired electron is easy to cause chemical reactions, damage to DNA (deoxyribonucleic acid), proteins and lipids and other important biomolecules, which in turn affects the cell membrane transport process, so that the function of the organizations, apparatus damaged, and promote the aging of the body. Red wine contains more antioxidants, such as phenolics, ellagic acid, flavonoids, vitamin C, vitamin E, trace elements such as selenium, zinc, manganese, etc., can eliminate or fight against oxygen free radicals, so it has the role of anti-aging and disease prevention.

Anti-cerebral thrombosis

Red wine can make the blood high-density lipoprotein (HDL) rise, and the role of HDL is to transfer cholesterol from extra-hepatic tissues to the liver for metabolism, so it is able to effectively reduce blood cholesterol, prevention and treatment of atherosclerosis. Not only that, the polyphenol substances in red wine can inhibit platelet aggregation and prevent thrombosis. Although white wine also has the effect of anti-platelet aggregation, but a few hours later there will be a "rebound", so that the platelet aggregation is more hyper than before drinking, and red wine is not this rebound phenomenon. The inhibition of platelet aggregation continued for 18 hours after drinking.

Prevention of cancer

Resveratrol, contained in the skin of grapes, has the best anticancer properties among hundreds of plants commonly eaten by humans. It can prevent normal cells from becoming cancerous and can inhibit the spread of cancer cells. In a variety of wines, red wine has the highest content of resveratrol. Because resveratrol can make cancer cells lose their ability to move, red wine is a good product to prevent cancer.

Breast Cancer Prevention

U.S. scientists have recently discovered that wine contains a chemical substance that can prevent breast cancer, and Roy Williams, of the San Francisco Wine Institute, said at a press conference in Washington, D.C., that they have found a substance that prevents breast cancer in red and white wines.

This substance has this effect because it is anti-estrogen, which is linked to breast cancer.

Promotes metabolism

Wine also contains p-aminobenzoic acid, which is a component of folic acid, promotes the synthesis of red blood cells and improves the utilization of pantothenic acid. Pantothenic acid is found in high levels within wine, 1 mg/liter, and adults need 5 mg-10 mg daily. Pantothenic acid deficiency can cause fatigue and digestive disorders. The high content of inositol within wine can promote the metabolism of fat in the liver and other tissues, effectively prevent fatty liver, reduce blood cholesterol, strengthen the absorption capacity of the intestine and promote appetite.

Protection of the heart muscle, prevention of heart disease

The wine contains a variety of inorganic salts, of which, potassium can protect the heart muscle, to maintain the heart beat. Calcium can calm the nerves; magnesium is a protective factor for cardiovascular disease, lack of magnesium easily caused by coronary atherosclerosis. These three elements are an important part of the composition of human bones and muscles.

Manganese has the role of blood clotting and synthesis of cholesterol, insulin. In red wine containing manganese 0.04 mg / l - 0.08 mg / l, moderate drinking, can regulate carbohydrates, fat, protein metabolism; selenium is a strong oxidant, together with vitamin E can prevent and control angina pectoris, myocardial infarction, to prevent elevated blood pressure, thrombosis, selenium content of red wine 0.08 mg / l - 0.20 mg / l.

American cardiologists have proved that drinking 200 milliliters of red wine daily can reduce platelet aggregation, plasma viscosity, so that blood clots are not easy to form, can prevent the occurrence of coronary heart disease. Because wine contains flavonoid polyphenols, can improve blood circulation. Researchers at Harvard University have shown that drinking wine can reduce heart disease mortality by 70%.

Soften blood vessels

Wine has the effect of treating anemia, softening blood vessels, improving circulation, and preventing disease. Dr. Kerry of New York found that wine contains a non-alcoholic component "resveratrol", which has the effect of lowering cholesterol and triglycerides.

Preventing diabetes

Moderate drinkers are 40% less likely to develop type 2 diabetes than non-drinkers. However, the researchers pointed out that the preventive effect of moderate drinking on diabetes requires the fulfillment of two major conditions: first, it is necessary to adhere to a healthy lifestyle, including a balanced diet, normal body weight, moderate exercise, and refusal to smoke; and second, strict control of the amount of alcohol consumed, preferably low-alcohol, low-sweetness wines, with a maximum of one glass per day for women and two glasses per day for men.

Lung care

In recent years, people have begun to gradually recognize the heart-healthy effects of red wine. Recent scientific research has also revealed that red wine has a positive effect on the lungs and lung protection. Researchers have found that red wine contains a natural compound that can help treat chronic bronchitis and emphysema. This compound, called resveratrol, is found in the skins of red grapes and inhibits the production of harmful chemicals that cause lung disease.

Drinking red wine in moderation reduces the risk of Alzheimer's disease

Scientists have long pointed out that drinking one or two glasses of red wine a day protects the heart and reduces the risk of coronary heart disease and atherosclerosis. Another new study shows that drinking some red wine can also protect the brain from Alzheimer's disease.

Experiments have found that red wine contains a lot of a substance called resveratrol (resveratrol), which is shown to have a significant antioxidant effect, can reduce Β amyloid (beta-amyloid) in the brain cells in the anomalous concentration, play a role in protecting brain cells. The prevailing view is that excessive aggregation of Β-amyloid in brain cells can cause damage to brain cells and lead to the development of Alzheimer's disease.

Lowering cholesterol

Researchers have announced that red wine contains chemicals that can lower cholesterol. Plants contain saponins that are helpful in lowering cholesterol, and grape skins contain saponins.

Wine protects against kidney stones

German scientists have found in a study that drinking wine in moderation protects against kidney stones. The University of Munich Medical Research Institute of medical scientists recently pointed out: more drinks can prevent the traditional statement of kidney stones is not scientific, not comprehensive, the most important thing is to look at what kind of drink, through the 45,000 healthy people and patients of clinical observation, researchers confirmed that people who often drink a moderate amount of wine, not easy to get kidney stones. The researchers found that people who drink different beverages in moderation have different risks of getting kidney stones. People who drink a quarter of a liter of coffee a day have a 10% lower risk of getting kidney stones than those who don't have the habit; people who drink tea regularly have a 14% lower risk; and those who drink wine regularly have the least chance of getting kidney stones, and their risk of getting the disease is 36% lower than those who don't have the habit.

Wine taboos

Avoid with seafood

"Red wine with red meat", which is in line with the rules of culinary science itself. The tannins in red wine combine with the proteins in red meat to encourage digestion to begin almost immediately. While fresh salmon, swordfish or tuna can pair well with light-bodied red wines because of their rich natural oils, when red wines are paired with certain seafood, for example: fillets of sole in Dover oil, the high level of tannins can seriously spoil the flavor of the seafood and even take on an off-putting, metallic taste of its own.

"White wine with white meat" is also a universal pairing recommendation. The flavors of some white wines may be overshadowed by beef or lamb, but they can be pushed to the limit by accompanying slabs of fish, shrimp, lobster, or grilled chicken breasts.

Avoid vinegar

As a rule, salads don't have an effect on the flavor of wine, but if they're tossed with vinegar, it can dull the sensations in the mouth, making the wine lose its vibrancy and make the flavors stagnant and bland. Lemonade is a good choice because the citric acid harmonizes with the character of the wine.

Cheese and wine are natural "bedfellows," but be careful not to pair spicy cheeses with lighter wines, or vice versa.

Avoid spicy foods

Spicy or aromatic foods can be difficult to pair with wine, but with spicy or fruity wines, you've got the right "lover".

Chocolate can sometimes have a negative effect on the taste of a wine, but some people report success with aged Cabernet Sauvignon. Banfi Bacchetto d'Aqui is a delightful wine that pairs well with chocolate, especially dark chocolate. This Italian wine is fruity and crisp, with just the right amount of natural acidity to balance the richness and sweetness of the chocolate, while keeping your mouth pleasantly fresh and clean.
