Red wine generally has no shelf life, and the so-called "shelf life" is the "drinking period". The so-called "shelf life" is the period during which the quality of goods can be guaranteed. The shelf life of wine is generally ten years in China, but there is no so-called shelf life abroad.

Red wine generally takes 10 to 20 years to reach maturity, which is the best drinking state. Wine is alive, from the formation of soil climate to the planting, germination, flowering, fruiting and ripening of fruit trees, which is one of the life processes.

Red wine is opened as follows:

Tools: red wine, bottle opener, fruit knife, spiral cone.

1, most wing-shaped bottle openers are not equipped with knives, so use a common fruit knife to remove the tin foil from the bottleneck, and then remove the tin foil cover.

2. Insert the spiral cone into the center of the cork, and then slowly rotate it into the cork. The metal cap around the spiral cone needs to be firmly pressed on the top of the bottle, while the wing arm of the bottle opener needs to be pressed on the bottleneck.

3. Hold the metal cap on the bottle with one hand, and turn the handle with the other hand to insert the spiral cone into the cork. When you rotate, the wings of the bottle opener will slowly rise. When the wings rise to the highest position, stop rotating.

4. Put the bottle on the table, and then press the two wings of the bottle opener with both hands. Meanwhile, the cork will slowly rise. When the wings are against the bottleneck, the cork comes out of the bottleneck completely.

Finally, we can enjoy red wine.

Precautions for red wine storage:

1. Need the right temperature. The theoretical temperature is about 12℃, and 7- 18℃ is also acceptable.

2. Avoid light, because ultraviolet rays will make wine precocious-avoid vibration.

3, placed horizontally, keep the cork moist, to prevent air from entering, wine oxidation.

4. Avoid being too wet to prevent bacteria from growing.

Preservation of red wine:

When red wine is stored for a long time, it should be kept cool and constant temperature, and the optimum storage temperature is 10℃ to 15℃. Both too low and too high temperature will damage the quality of red wine. At the same time, red wine needs to be stored away from light, and red wine is exposed to strong light. Whether it is natural light or artificial light, red wine will give off heat and lose its fresh taste prematurely.

The wine bottle must be placed obliquely, horizontally or upside down, so that the wine liquid can contact with the cork to keep the cork moist, so that the outside air can not contact with the wine liquid because the cork is dry, which leads to the deterioration of the red wine.

It is recommended to drink open red wine once. If you can't finish eating, you can immediately put the cork back as it is and put it in the refrigerator. If you can't put it back, you can also use plastic wrap, which can be stored for 3~5 days without significantly reducing the quality of the wine.
