Is a bottle of white wine still good after having frozen?

No, a bottle of white wine is not good after having frozen. Here's why:

* Expansion and Contraction: When wine freezes, the water inside expands. This expansion can cause the bottle to crack or break.

* Changes in Texture and Flavor: Freezing can cause the wine to become cloudy and change in texture. The freezing process can also alter the flavors and aromas of the wine, making it taste less enjoyable.

* Loss of Carbonation: For sparkling wines like Champagne, freezing can cause the loss of carbonation, resulting in a flat and less enjoyable experience.

In summary: While freezing a bottle of white wine might not immediately ruin it, it's highly likely to negatively impact its quality and flavor. It's best to store white wine at a cool temperature (around 50-55°F) to preserve its best quality.
