You had both red and white wine in a refrigerator that malfunctioned heated the to quite warmhot Is champagne still good if cooled again?

Unfortunately, no, champagne is likely not good after being heated to warm or hot temperatures. Here's why:

* Spoilage: Champagne is a delicate beverage, and the warmth encourages the growth of bacteria and yeast. This can lead to spoilage, changing the flavor and potentially making it unsafe to drink.

* Carbonation Loss: The warm temperature will cause the carbon dioxide bubbles in the champagne to dissipate quickly. This significantly impacts the taste and texture, leaving a flat and less enjoyable experience.

* Oxidation: Exposure to warm temperatures accelerates the oxidation process, which alters the flavor and aroma of the champagne.

Cooling the champagne again won't reverse these effects.

The Bottom Line: If your champagne has been heated, it's best to discard it. While it might be tempting to try and salvage it, the risk of spoilage and unpleasant taste outweighs the potential reward.
