How Exactly Should the Temperature of the Wine Cellar Be Controlled?

Most experts suggest that the ideal wine storage temperature should be between 11-14 degrees Celsius (Five2-FiveFive degrees Fahrenheit). Recently, a new study shows that the critical range of wine storage temperature is wider than previously expected.

The wine master, Jancis Robinson, once said that the temperature of a perfect cellar would not fluctuate easily, wine cellar temperature control is hard to do.

Effect of temperature change on wine taste

Tannins polymerize in wines aged under natural conditions. When the heat affects the polymerization process, the wine will lose its original fruit flavour.

Any large temperature change will accelerate the oxidation of wine, resulting in changes in tannin molecules:

If the storage temperature is too low, the tannin flavour will be too prominent.

If the storage temperature is too high, the tannin flavour will be too weak.

The change of temperature will also lead to the expansion and contraction of cork, increase the contact between wine and oxygen, and accelerate the oxidation of the wine.

Wine storage skills of professional masters

The perfect cellar temperature is very difficult for the world's outstanding wine masters to control, so they will choose to slightly adjust the cellar temperature.

For a wine that can be drunk immediately, it can be4-18Centigrade(40-6FiveFahrenheit degree)It's stored for up to a year. As long as the temperature of the cellar does not fluctuate more than five at Celsius, the wine retains all its flavour.

For the sake of long-term ageing or resale investment, a more rigorous wine storage environment is needed. Most quality red wines should be stored at a temperature of at least 18 degrees Celsius (6Five degrees Fahrenheit), but they also need to be adjusted according to the grape variety.

White wines are generally cooler to store, usually at 7-10 degrees Celsius (4Five-Five0 degrees Fahrenheit). Red and white wines of the same quality must not be stored at the same temperature. In the same way, there may be three different wine storage areas for different wines of different years.
