Dear Dr. Vinny,

I put a bottle of Champagne in the freezer and forgot to take it out before it froze. Is it still drinkable?

—Kay, Los Angeles

Dear Kay,

Drinkable? Sure. Enjoyable? Hard to say.

Before we get to why, this is a good opportunity to remind readers that putting a bottle of wine in the freezer is not the fastest way to chill it. The best way to chill a bottle of wine is to submerge it in a bath of ice, water and salt. I never recommend the freezer because not only does it take longer, a forgotten bottle of any wine in a freezer might break as the freezing causes the wine to expand, or the cork may be pushed out.

If your bottle is intact, you can defrost the wine and it won’t be harmful to drink. Still wines will probably taste the same, but frozen-then-defrosted Champagne will likely have a marked reduction in carbonation.
