This suitable environment depends on six important factors, namely, six aspects that should be paid attention to in preserving a good bottle of wine, namely, temperature, humidity, light, vibration, smell and posture.
First, constant temperature:
Temperature is the most important factor in wine storage, because the taste and aroma of wine are most volatile at a suitable temperature. More precisely, it will make people feel most comfortable in the process of alcohol volatilization. If the wine temperature is too high, bitter, sour and other flavors will run out; If the temperature of wine is too low, it can't effectively volatilize the proper aroma and delicious taste. Alexander Ji. Padel, a professor of chemistry at the University of California, has done experimental research. If the general standard of wine storage is 13℃, if the temperature rises to 17℃, the ripening speed of wine will be 0.2 ~ 1.5 times of the original. If the temperature rises to 23 degrees Celsius, the ripening speed will be 2 ~ 8 times, and the temperature will rise.
Of course, the change of ripening speed is also different because of the different grape varieties and brewing methods used in brewing. Generally speaking, the best storage temperatures for different wines are as follows:
Semi-sweet and sweet red wine 14- 16℃ dry red wine 16-22℃
Semi-dry red wine 16- 18℃ dry white wine 8- 10℃
Semi-dry white wine 8- 12℃ semi-sweet and sweet white wine 10- 12℃
Brandy 65438+ Champagne (sparkling wine) 5-9℃ below 05℃
It is best to keep the temperature of wine constant and try to avoid short-term temperature fluctuations. Generally, the higher the temperature, the faster the wine ripens; When the temperature is low, the growth of wine will be slower. Some people may ask, if the temperature is higher, the wine will ripen quickly, so it will take a long time to ripen. Isn't it ready to drink right away? In fact, rapid ripening will make the flavor of wine rough, and sometimes excessive oxidation will make wine deteriorate.
Second, moisturizing:
The influence of humidity mainly acts on cork. If the humidity is too low, the soft cloth plug will dry, which will affect the sealing effect, let more air contact with the wine, accelerate the oxidation of the wine, and lead to the deterioration of the wine. Even if the wine does not deteriorate, the dry cork is easy to break or even break when opening the bottle, and then a lot of sawdust will inevitably fall into the wine, which is a bit annoying; If the humidity is too high, sometimes it is not good, the cork is easy to get moldy. In the wine cellar, it is easy to breed a beetle, which is as big as a louse and will bite the cork. The most suitable storage humidity of wine is between 50% and 80%, but some tests of internationally renowned wine cellars show that more than 90% humidity does not affect the storage of wine.
There is also a little trick about humidity control of thermostatic wine cabinet. If the humidity in the wine cabinet is too high in bad weather, you can dry the water drops in the bottle and the box with a dry cloth and open the door of the wine cabinet properly for ventilation. In order to protect the label of wine, you can cut a corner from the plastic bag at home and stick it on the label. If the humidity in the wine cabinet is too low, you can put a small water dish in the wine cabinet to increase the humidity.
Third, avoid light:
Wine should avoid strong light, especially ultraviolet rays will make wine precocious, and transparent glass bottles will make this problem more serious. Although the dark green wine bottle can block some ultraviolet rays, it can't completely stop the invasion of ultraviolet rays. Therefore, wines that want to be preserved for a long time should be kept away from light, and wine cellars or professional wine incubators should be kept away from light. Fourth, avoid vibration:
The damage of vibration to wine is purely physical. The change of wine in the bottle is a slow fermentation process. Vibration will disturb the molecular structure of wine, accelerate the ripening of wine and make wine rough. So stay away from the vibration and don't move frequently.
Five, no smell:
Wine is like a sponge, sucking the surrounding flavor into the bottle. The cork of wine is actually the "respiratory organ" of wine, and the pungent taste will penetrate into wine through the cork, so wine should not be stored with other foods to prevent the smell from penetrating into wine.
Six, flat:
Winemakers call lying wine "sleeping beauty". Wine is very important. Every bottle of wine will continue to grow and mature before it is opened. When the wine is laid flat, its cork will remain moist and air will not enter, so the quality of the wine will not change.
Seven, the high-tech alternative product of wine cellar-Meijing wine thermostat;
In modern cities, ordinary families can't design and dig a professional wine cellar to collect wine. Considering the storage requirements of wine and the needs of professional collectors, professional wine thermostats came into being. The wine thermostat of Shenzhen Meijing Technology Co., Ltd. is a high-tech refrigeration equipment to replace the wine cellar to store wine. As a professional wine thermostat, it is strictly designed from the aspects of constant temperature, moisturizing, light protection, shock absorption and ventilation. To ensure that the wine always keeps the best storage and drinking temperature.
