For wine collectors and consumers, there are three major conditions that they should look out for, in order for the wine to maintain its flavor, taste and quality. These conditions include:
Every wine storage process is important and should be adhered to. The correct wine storage temperature is the most ideal of the three conditions and should be highly maintained.
A recommended storage temperature of between 45 and 65 degrees Fahrenheit should be maintained, with 50 and 55 degrees Fahrenheit being the optimal range.
Why Is The Correct Wine Storage Temperature Important?
To begin with, fine wine takes ages to develop. To attain this, favorable temperature conditions should be observed to avoid lower or higher temperature. Very cold temperatures below 40 degrees Fahrenheit slow down the ageing of wine, which may also keep it from having the required chemical reactions.
On the other hand, high temperature of more than 65 degrees Fahrenheit can damage the wine by speeding up the chemical reactions. This results to a change in color to brown due to oxidization from heat. Adverse temperatures affect the flavor and quality of the wine.
Wine should be keep at its optimal temperature. A temperature of below 50 degrees Fahrenheit slows the ageing of the wine but doesn’t affect the wine if the temperature is kept constant. When changing the temperature, do it slowly and steadily by not more than 5 degrees Fahrenheit annually.
For instance in France, wine is kept in caves where there is natural underground temperature of around 55 degrees Fahrenheit. But since everyone doesn’t have an underground storage or cellar, a refrigerator or cool climate can do.
In addition, keeping the right temperatures for the wine is a key in obtaining a good flavor and quality wine. Try to avoid temperature variations, be it for a longer or shorter period of time. Temperature change causes the volume of wine to increase as temperature rises, thus reducing the ullage volume and then contracts as temperature falls, thus also reducing the ullage volume. This change in ullage volume leads to increased oxygen transmission by mass transfer of gas.
Also, another important aspect as to why the wine should be kept at optimal, or at the right temperature, is to prevent it from passing through the cork. Temperature change causes premature aging and breathing. When the wine’s temperature is increased, they can force the wine out of the cork.
At the same time, lowering the wine’s temperature forces the air back into the wine bottle. These temperature variations mostly affect older wines which tend to have a less tight seal of the cork.
While ensuring the wine is stored within the required wine storage temperature range, try to keep the temperature as steady as possible at all times. But in case a need arises for you to change it, do so gradually to reduce the risk involved. This applies more to red wines, as they are affected drastically to changes in temperature as compared to white wines.
