Beer can freeze, and the temperature at which it freezes depends on several factors, including the alcohol content, sugar content, and insulation of the beer. Most beers freeze at around 28ºF (-2 ºC) assuming the beers ABV% is in the 4-6% range. However, beers with a higher alcohol content will require more time to freeze than lighter beers or those kept in glass containers. A reference chart shows that a 10% solution of ethanol in water will freeze solid at 25 degrees Fahrenheit.

It is possible to put beer in the freezer to cool it down quickly, but it is important to set a timer and not forget about it, as carbonated drinks tend to explode if left in the freezer too long. Wrapping a wet paper towel around the bottle and placing it in the freezer for ten minutes can help chill the beer quickly. However, it is not recommended to freeze beer intentionally, as it can alter the flavor and aroma in ways that may not be enjoyable.

In summary, beer can freeze at around 28ºF (-2 ºC), but the exact temperature depends on several factors, including the alcohol content, sugar content, and insulation of the beer. It is possible to cool beer quickly by placing it in the freezer for a short time, but it is not recommended to intentionally freeze beer.
