Does frozen beer lose alcohol?

No, freezing beer does not make it lose alcohol.

Here's why:

* Alcohol's freezing point: Alcohol freezes at a much lower temperature than water (-173.4°C or -279.5°F). This means that even if you freeze a beer, the alcohol will not freeze.

* Water expands when it freezes: When water in beer freezes, it expands. This expansion can cause the bottle or can to burst.

* Taste and quality: Freezing beer can affect its taste and quality. The freezing process can cause the beer to become cloudy and develop off-flavors.

So, while freezing doesn't affect the alcohol content, it's generally not recommended for preserving or enjoying your beer.
