First, the first step is to remove the stems, which means to remove the grape berries from the comb-shaped branches and stems. Because the branches and stems contain a lot of tannic acid, they have an unpleasant taste in the wine.

Second, squeeze the fruit. When making red wine, the grape skins and grape flesh are pressed at the same time. The red pigment contained in the red wine is released when the grape skins are pressed. Because of this, all red wines are red in color.

3. Juicing and fermentation. After the juice is squeezed, the raw material for winemaking—grape juice—can be obtained. With wine juice, you can brew good wine. Wine is a product obtained through fermentation. After fermentation, the sugar contained in the grapes will gradually convert into alcohol and carbon dioxide. Therefore, during fermentation, there is less and less sugar and more and more alcohol. Through the slow fermentation process, red wine with a delicate aroma and delicate taste can be produced.

Fourth, add sulfur dioxide. To maintain the fruitiness and freshness of the wine, sulfur dioxide treatment must be added immediately after the fermentation process. Sulfur dioxide prevents the oxidation of wine caused by oxygen in the air. About 3 weeks after fermentation, new wine must undergo its first sedimentation and barrel change. The second precipitation takes 4 to 6 weeks. The number of times and the sequence of precipitation are exactly what you want to achieve.

Five. After the wine has been stored in barrels for 3 to 9 months, it will be bottled. In the past, wine bottles were sealed with corks, but now (after 2001) many technologically innovative bottling plants are using new vacuum-sealed rotary wine bottles.

Steps in tasting red wine

The first step: control the temperature of the red wine. Traditionally, the temperature for drinking red wine is cool room temperature, between 18 and 21 degrees Celsius (white wine is between 9 and 12 degrees Celsius). At this temperature, red wines of all vintages are at their best. A bottle of chilled red wine will have more pronounced tannins (the astringent substances in wine) than a bottle of red wine at cool room temperature, so the taste will be more astringent. White wine is just the opposite. It is refreshing and sour, so it is suitable for drinking chilled. The correct thing to do when drinking is to pinch the stem of the goblet with your fingers instead of holding the cup with your hands, otherwise the difference in temperature of the wine will affect the coordination of the wine.

Step 2: Sober up. A bottle of wine that has been dusted for many years will have a peculiar smell when it is just opened. At this time, it is necessary to "awaken" the wine. Pour the wine into a beautiful decanter and wait for ten minutes, the odor of the wine will dissipate. Decanters are generally required to maximize the contact area between wine and air. After the red wine is fully oxidized, its rich aroma is revealed. This process can be extended, preferably an hour, to create an atmosphere overflowing with wine.

Step three: watch the wine. The red color of red wine is enough to seduce people's hearts. When pouring red wine, the basic requirement is to hold the glass horizontally and prevent the wine from spilling. Place the red wine glass horizontally on a white paper under sufficient light and look at the edge of the red wine. The wine with clear layers is mostly new, and the wine with uniform color is a bit old. If it is slightly brown, it may have touched a bottle. A vintage wine.

Step 4: Drink. Before drinking the wine, take a deep sniff in the glass. At this time, you can already appreciate the delicate aroma of the red wine. The fruity aroma of the new wine is very strong, while the old wine will deeply restrain this flamboyant personality. Take a sip of red wine, let it stay in your mouth for a while, roll it on your tongue, take a deep breath to fully experience the red wine with your senses, and finally swallow it all, a delicate fragrance will immediately linger in it.

Step 5: Wine sequence. When drinking, you should drink according to the principle of fresh food first and old food last, light food first and strong food last.
