6 The ideal storage temperature
As the temperature rises, the wine molecules kinetic energy
increases and this accelerates the aging process causing
the wine to deteriorate. Consequently, storage temperatures
of between +10 °C and +12 °C are recommended for storing
wine over prolonged periods. Maintaining a constant
temperature is most important, as fluctuations during
storage will impair the quality of the wine. Furthermore,
the temperature at which a wine is consumed also plays a
crucial role in how it tastes. Red wines should be served at
a warmer temperature than white wines because they
contain more tannins (polyphenols). Tannins react with
oxygen more quickly at higher temperatures. This is what
happens in the process of allowing a wine to breathe, when
the full aroma and taste are only achieved once the wine
has combined with oxygen. The length of time for which
a wine should breathe depends on its variety and quality.
Barolo, Rioja, Burgundy and Bordeaux each take a different
amount of time to develop. In general, the longer a wine
matured in the barrel, the more likely it is to need a longer
breathing time for full enjoyment.

for wine.
---
The ideal long term storage temperature
for wine is between + 10 °C and + 12 °C.
It is critical that the temperature is
kept as constant as possible because
this is the only way that a wine’s natural
harmony will be preserved.
