What Is the Freezing Point of Beer?


Quick Answer

The freezing point of beer depends on its alcohol content, but it generally freezes at around 28 degrees Fahrenheit. Beer is typically between 6 and 20 proof. For reference, 24 proof liquor freezes at 20 degrees, 64 proof liquor freezes at -23 degrees, and 84 proof liquor freezes at -30 degrees.

Full Answer

In practical terms, this means that most freezers are cold enough to freeze beer. The freezing point of ethanol, or drinking alcohol, is -173 degrees Fahrenheit, and the freezing point of water is 32 degrees Fahrenheit. The more alcohol a beverage has, the lower its freezing point is. Some stronger beers, such as barley wines and imperial stouts, are around 24 proof, but they still have a low enough alcohol content to freeze. Excessively old temperatures mask the flavors of good beer, so there is nothing to be gained from storing beer in the freezer.
