Will wine change flavor after being exposed to extreme tempurtures or frozen?

Yes, wine can change flavor after being exposed to extreme temperatures or frozen. Here are some effects that extreme temperatures can have on wine:

Freezing: When wine is frozen, the water in the wine freezes, causing the alcohol and other components to become concentrated. This can result in a sweeter and more alcoholic taste. When the wine is thawed, the flavors may be muted and the texture may be watery.

High temperatures: When wine is exposed to high temperatures, the alcohol and other volatile compounds can evaporate, resulting in a loss of flavor and aroma. The wine may also become oxidized, which can lead to a cooked or Sherry-like flavor.

In general, it is best to store wine at a cool, consistent temperature to preserve its flavor and quality. The ideal storage temperature for most wines is between 55°F and 65°F.
