Alcohol does freeze, but the freezing point varies depending on the type of alcohol and its proof or alcoholic concentration. The proof of an alcohol is calculated by multiplying its alcohol percentage by two. For instance, vodka, which is 40% alcohol, is 80 proof. The freezing point of pure ethanol alcohol is -173 °F (-114 °C), but alcoholic beverages contain a mixture of alcohol and water, which raises the freezing point. The freezing point of an alcoholic beverage depends on its alcohol content, with lower alcohol content resulting in a warmer freezing point, and higher alcohol content resulting in a colder freezing point. For example, beer, which has a low alcohol content, freezes at around 28 °F, while 80-proof vodka will not freeze at temperatures attainable in a home freezer.

The freezing point of pure alcohol
The freezing point of alcohol is influenced by the strength of the attractive forces between its molecules. Water molecules are "stickier" than ethanol molecules, allowing them to form fixed arrays and freeze at a higher temperature of 32 °F (0 °C). Conversely, alcohol requires a much lower temperature to freeze because its molecules have weaker attractive forces and require colder conditions to become "stuck" in a solid state.
The freezing point of alcoholic beverages, which are mixtures of alcohol and water, falls between the freezing points of pure alcohol and water. The exact freezing temperature depends on the alcohol content, with beverages of lower alcohol concentration freezing at warmer temperatures. For example, beer and wine, which have lower alcohol content, typically freeze in home freezers set at 0 °F (-18 °C). However, high-proof alcohols, such as vodka and Everclear, will not freeze in a home freezer due to their higher alcohol content.
It is important to note that the freezing points provided for alcoholic beverages are not exact and can vary based on factors such as specific alcohol content and container type. Small variations in alcohol content can significantly impact the freezing point, and certain mixtures may require temperatures much lower than those achievable in a home freezer to freeze. Therefore, it is essential to exercise caution when freezing alcoholic beverages to avoid unintended consequences, such as exploding containers due to water expansion during freezing.

Alcoholic concentration and freezing point
The freezing point of alcohol depends on its alcoholic concentration, also known as its proof, which is double its alcohol percentage. For example, 80-proof vodka is around 40% alcohol. The higher the proof of an alcohol, the lower its freezing point—in other words, higher alcoholic concentration makes a spirit harder to freeze.
The freezing point of pure ethanol alcohol is -173 °F (-114 °C). However, most alcoholic beverages contain more water than alcohol, so their freezing point will be much higher and somewhere between the freezing points of water and pure ethanol alcohol. The freezing point of water is 32 °F (0 °C).
The exact freezing point of any beer, liquor, or wine is dependent on its alcohol by volume (ABV). The lower the alcohol content, the warmer the freezing point and the quicker it will freeze. The higher the alcohol content, the colder the freezing point and the longer it can stay in the freezer. For example, wine is 85 to 90% water, so it freezes at about 20 °F (-6.7 °C). The water freezes first at 32 °F (0 °C) and then the alcohol. It will be slushy for a while before it becomes solid.
Liquors with a high proof, such as 190-proof Everclear, will not freeze in a home freezer. Eighty-proof vodka will also survive unfrozen. Beer and wine have significantly less alcohol than liquors and will freeze, though this is not guaranteed. It takes around 90 minutes for beer to freeze in a home freezer set at 0 °F (-18 °C).

Freezing points of different types of alcohol
The freezing point of alcohol depends on the type of alcohol and the atmospheric pressure. Pure ethanol (also known as ethyl alcohol) freezes at around -173 °F (-114 °C), while methanol (or methyl alcohol) freezes at around -144 °F (-97.6 °C). However, most alcoholic beverages contain a mixture of alcohol and water, which affects their freezing point.
Beer, for instance, typically has an ABV (alcohol by volume) ranging from 3% to 12%, and its freezing point can vary accordingly. On average, beer freezes at about 28 °F (-2 °C). Wine, which usually has a slightly higher ABV than beer, typically freezes at around 23 °F (-5 °C). However, it's important to note that wine can take several hours to freeze solid, and it may turn slushy first due to the water content freezing before the alcohol.
Liquors, such as vodka, generally have a higher alcohol content than beer or wine. For example, vodka is typically around 80 proof (40% alcohol) and has a freezing point of -16.5 °F (-27 °C). This means it won't freeze in a standard home freezer. Similarly, Everclear, a high-proof alcohol, has a freezing point of -173.2 °F (-114 °C) and will not freeze in a conventional freezer.
The freezing point of alcohol also depends on other factors, such as the size of the container and any additional ingredients or mixers. For instance, a cocktail or a margarita will freeze differently from a pure spirit due to the other ingredients. Additionally, the proof or alcoholic concentration of the beverage plays a significant role in determining its freezing point. In general, the higher the proof, the lower the freezing point, making it harder for the beverage to freeze.

Atmospheric pressure and freezing point
The freezing point of alcohol depends on the type of alcohol and the atmospheric pressure. The freezing point of ethanol, or ethyl alcohol (C2H6O), is around −114 °C, −173 °F, or 159 K. The freezing point of methanol, or methyl alcohol (CH3OH), is approximately −97.6 °C, −143.7 °F, or 175.6 K. The exact values for the freezing points can vary depending on the source due to differences in atmospheric pressure.
Atmospheric pressure has a significant influence on the freezing point of substances, including alcohol. Typically, as atmospheric pressure increases, the boiling point of a liquid rises. Conversely, at higher altitudes where atmospheric pressure is lower, liquids tend to boil at lower temperatures. This relationship between atmospheric pressure and boiling points also extends to freezing points.
In the case of ethanol, the melting point and freezing point are the same: −114 °C. This temperature represents the transition of ethanol from a solid to a liquid state (melting) or the transition from a liquid to a solid state (freezing). This phase transition occurs at a specific temperature, known as the melting or freezing point, and it is dependent on the pressure exerted on the substance.
When determining the freezing point of alcoholic beverages, it is crucial to understand that they are a mixture of alcohol and water, with varying ratios of these components depending on the type of beverage. The freezing point of pure water is 0 °C or 32 °F, while the freezing point of pure ethanol is significantly lower at −114 °C or −173 °F. The freezing point of an alcoholic beverage will fall somewhere between these two temperatures, depending on its alcohol content.
The higher the alcohol content in a beverage, the lower its freezing point will be. For example, vodka, with an alcohol content of around 40%, has a freezing point of about −16.5 °F (−27 °C). On the other hand, beverages with lower alcohol content, such as beer and wine, will have higher freezing points. Wine, which is approximately 12% alcohol, freezes at around 20 °F (−6.7 °C). Therefore, the freezing point of alcohol is influenced by both the type of alcohol and the atmospheric pressure, and this relationship is crucial in understanding the phase transitions of alcoholic substances.

Freezing alcohol in a bottle
Alcohol does freeze, but not all types freeze at the same rate. The freezing point of alcohol depends on the type of alcohol and the atmospheric pressure. The freezing point of pure ethanol alcohol is -173 °F (-114 °C), while the freezing point of methanol or methyl alcohol is around -144 °F (-97.6 °C). The freezing point of a water-alcohol mixture will be somewhere between the freezing points of water and pure ethanol.
The freezing point of alcoholic beverages will depend on their alcohol content. The higher the alcohol content, the lower the freezing point. For example, 80-proof vodka has a freezing point of -16.5 °F (-27 °C), while 190-proof Everclear freezes at -173.2 °F (-114 °C). Beer and wine have lower alcohol content and will freeze at temperatures achievable in a home freezer. However, it is important to note that beer and wine are bottled under pressure, and freezing them can cause the bottles to crack or explode.
When freezing alcohol in a bottle, it is important to consider the alcohol content and the freezing point of the beverage. For beverages with a high alcohol content, such as vodka or Everclear, it is generally safe to store them in a freezer, as their freezing points are well below the temperature of a standard freezer. However, for beverages with lower alcohol content, such as beer or wine, freezing may cause the liquid to expand and the bottle to crack or explode.
If you are aiming to create a frozen alcoholic drink, it is recommended to consult a recipe. Knowing the freezing points of the ingredients will be helpful, but it may involve some trial and error. Finding a tried-and-true recipe can save time and provide better results. Additionally, using a non-metal freezer container and stirring the mixture periodically can help achieve a slushy consistency.
