Vodka freezes at a much lower temperature than water due to its ethanol content. Ethanol, the alcohol in vodka, freezes at around -16 degrees Fahrenheit. Therefore, vodka will not freeze in a typical freezer, which is usually set at zero degrees Fahrenheit. However, it is important to note that the optimal drinking temperature of vodka is somewhere between 32-39 degrees Fahrenheit. Storing vodka in the freezer can mask some of its best qualities, such as its subtle scents and flavors. Additionally, when vodka gets warmer, it releases more volatiles and the smell of pure alcohol can be overwhelming. Therefore, it is recommended to store vodka at a consistent temperature and avoid exposure to high heat. While it is not dangerous to drink vodka that has been stored in the freezer, it is important to know what you are drinking.
