Basic knowledge of red wine, red wine is a relatively common wine, many people like to drink red wine, and think that drinking red wine is very emotional. However, drinking red wine is actually very particular, and there is a lot of knowledge about red wine. Let's share the basics of red wine.
Basic knowledge of red wine 1 wine tasting
1. Observe its color-pour the wine into the goblet, hold the foot of the goblet and observe its color.
2. Smell its fragrance-gently shake the glass to release the fragrance and smell its fragrance.
3. Taste-take a sip, let the wine dissolve on the tip of the tongue, and feel its taste and sweetness.
Entrance selection
Look at the category
For example, according to the sugar content of wine, it can be divided into dry type, semi-dry type, semi-sweet type and sweet type. Dry wine doesn't feel sweet and sour; Semi-dry wine has a slightly sweet feeling when drunk; Semi-sweet wine tastes sweet and refreshing; Sweet wine tastes obviously sweet and slightly drunk.
Look at the appearance
The appearance of wine is mostly clear, transparent and shiny, and the color is consistent with the name of the wine. Watching red wine flow from the top of the glass on a white background is not cloudy. Look at the speed at which the wine flows evenly from the glass wall. The slower the flow, the better the quality of the wine.
Tilt the side of the glass at 45 degrees and observe a layer of water at the junction of red wine and glass wall. The wider, the higher the alcohol content. Different colors can appear at the junction of water body and wine body, indicating the year of wine. Blue and lavender are three to five years old. Red bricks have a history of 5 to 6 years. Amber is 8 to 10 years. Orange means it has expired.
Look at the year
This red wine is more suitable for the old world, so after choosing French or Italian wine, you must choose a "good year" and the taste must be different. For example, French wines are priced by the day, and the year of grapes is related to the rainfall before the harvest of grapes that year. If there is too much rain, the wine will become weak.
For example, 199 1 and 1992, it rains continuously in Bordeaux. As a result, the grapes in these two years are not sweet enough and the skin is thin. After brewing, the tannin content is obviously insufficient and the taste is poor. This is why gourmets often use chronologies to compare and choose wines.
Look at the place of origin and place of origin
On the big side, let's first look at the wine in the new world or the wine in the old world. Old world wines in Europe generally taste more complex and elegant, while new world wines taste more lively and pleasant. It's hard to say who is better, depending on personal taste preferences;
Then look at the place of origin. Every wine producing country has different producing areas, and their styles and qualities are different. For example, Bordeaux and Burgundy in France are completely different styles.
Look at the aroma and taste.
Until the real entrance, you can feel the texture, taste and level of red wine. If you leave high-quality red wine in your mouth, you should have a smooth feeling, slowly feel its mellow, and then the taste will be enriched;
The aroma of wine will make you aftertaste endlessly, and it will not be scattered in your mouth for a long time. At the same time, these scents should be balanced, harmonious, elegant and pleasant. The taste of such wine should also be comfortable and pleasant, and all kinds of flavors are delicate.
Red wine storage
cork
Cork has the characteristics of low density, good elasticity, strong flexibility, air tightness, corrosion resistance, decomposition resistance and difficult deterioration, which can keep the quality of wine unchanged over the years.
Usually, the length of cork used in general grade wine is about 3.5 cm to 5 cm, which is better than that used in high-quality wine. The length of cork is more than 5 cm. Generally, high-quality wines use long corks, but wines using long corks are not necessarily high-quality wines.
room temperature
We often hear that a certain wine is most suitable for "drinking at room temperature". What does room temperature mean? In fact, room temperature usually refers to the temperature in the country of origin, not the room temperature in China. For French wines, room temperature usually refers to 16 to 18 degrees Celsius.
For China, which has a vast territory, except for the cold winter, most of this temperature needs to be achieved by refrigeration. Never put the shower at room temperature and take it for granted that it is "room temperature".
Wine doesn't get better with age.
The older the wine, the better it smells. After the peak of wine aging, it will only go from bad to worse, just like a beautiful woman has her twilight years, and then she will gradually get old and enter a degenerate period. Therefore, wine also needs to be drunk at the right time to taste its best flavor.
Store your favorite wine.
Find a cool and quiet corner as a place to store wine to avoid strong or abnormal smells (such as paint smell and durian smell) and excessive temperature affecting wine; Don't be too addicted, always take it out and enjoy wiping. The last thing wine needs is shaking and light stimulation.
Long-term storage, lying down is better
If you want to store wine for a period of time, it is best to keep the bottle flat so that the cork can contact with the wine liquid and keep it moist. If the bottle is placed upright, the cork will be excessively dry, which will let air in and destroy the quality of the wine.
Selection of tasting cup
Only by choosing the right tasting cup can we taste the wine completely. Tulip-shaped or neck-necked transparent wine glasses are the best ones used in wine tasting, which can concentrate the aroma of wine near the mouth of the glass and make it easy to judge the smell. Don't have carvings or other colors, so as not to misjudge the color of the wine.

High-concentration lipoprotein can transport cholesterol in blood to the liver, where it can be converted into cholesterol-cholic acid to prevent cholesterol from depositing on the intima of blood vessels, thus preventing arteriosclerosis.
Procyanidins in wine play an important role in preventing and treating cardiovascular diseases. In the arterial wall, proanthocyanidins can stabilize collagen fibers that form various membranes, inhibit amino acid decarboxylase, avoid producing too much histamine that can reduce the permeability of arterial wall, and prevent arteriosclerosis.
