Dear Dr. Vinny,
Should I be concerned about wine freezing in my car if it’s below freezing outside?

Dear Cheryl,
Alcohol’s freezing point is far lower than that of water, but wine is still mostly water. You probably know that you can put a bottle of vodka in the freezer and it won’t freeze, but that’s not true for a bottle of wine. The freezing point of a bottle of wine is about 15° to 20° F, depending on the alcohol content. And while freezing wine in an ice tray or plastic bottle is a great way to save it for another day, freezing wine in a glass bottle can cause the cork to be pushed out or the glass to break.
