What is the freezing temperature of alcohol?
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).
