Is wine still good if it has been accidently frozen during delivery? — D. Hanks.
As a general rule, freezing and thawing beverages has little or no effect on flavor. You can freeze grape juice, milk, soda, etc. without any ill effects. Wine is the same way. Freezing it in a glass bottle probably isn’t a good idea (if you have a choice), because the expansion of the wine during freezing can push out the cork or break the glass.
