Pure ethanol freezes at -114 °C (-173.2 degree Fahrenheit).

Alcoholic beverages will freeze somewhere between -114 °C

and 0 °C depending on the alcohol content.

The kind of alcohol that people can drink is called ethanol and

it has a freezing point of -114 degrees Celsius (-114 °C). However,

there are many other kinds of alcohol (such as methanol, rubbing

alcohol or inspirational, banal, and many others) and each one has

a different freezing point. Water freezes at 0 °C and the coldest

most home model freezers will go down to -18 °C. That is why

alcoholic beverages won't freeze in your home freezer. However,

most alcoholic beverage are not pure ethanol, but instead a mixture

of water and ethanol. The freezing point of the mixture depends on

how much of each component is in it. For instance, something with

only 1% ethanol will freeze just a little below 0 °C, whereas

something with 95% ethanol will freeze pretty close to -114 °C. How

much ethanol is in a particular alcoholic beverage is listed on the

bottle, either as a percentage or as a "proof" which is just 2

times the percentage (100 proof =B= 50% ethanol).
