Freezing Alcohol: Safe Or Not?

Alcoholic beverages have a freezing point that depends on their alcohol content. Liquors with a high alcohol content will not freeze in a home freezer, but beer and wine, which have a lower alcohol content, will. Freezing temperatures can change the texture and taste of some drinks. Vodka, gin, and other clear spirits can be stored in the freezer without losing their quality, but drinks with more nuanced flavors, such as whiskey or tequila, can lose their character if subjected to extreme temperatures.

Freezing alcohol can change its flavour and texture

However, this increase in viscosity comes at the cost of muting flavours and aromas. As a spirit gets warmer, it releases more volatiles, which are compounds that easily vaporize. Therefore, when a spirit is too cold, the aromas and flavours might seem non-existent. This is especially true for spirits with more subtle flavour profiles, such as whisky, tequila, and gin. The freezing process can also cause undesirable texture changes in liqueurs, with creamy liqueurs separating and fruity liqueurs losing their flavour.

In addition, freezing alcohol can cause the liquid to expand, which can compromise the seal or even cause the bottle to break. This is more likely to occur with wines and beers, which have lower alcohol content and are bottled under pressure.

Alcohol with a lower ABV is more likely to freeze

The answer to the question of whether it is safe to store alcohol in freezing temperatures depends on the beverage's alcohol content. Liquors with a lower alcohol content are more likely to freeze, while those with a higher alcohol content are less likely to freeze.

The freezing point of pure ethanol alcohol is -173°F (-114°C). However, alcoholic beverages are a mixture of alcohol and water, which means their freezing point is somewhere between that of pure ethanol and water. Water freezes at 32°F (0°C). The exact freezing point of a beverage depends on its alcohol by volume (ABV or proof): the lower the alcohol content, the warmer the freezing point, and the quicker it will freeze.

For example, beer and wine have a lower alcohol content than liquors and will freeze. If a warm beer or white wine is placed in the freezer, it will be ready to drink in no time. However, if left in the freezer for too long, the water in the beverage will freeze, creating a slush that can affect the taste and quality.

Spirits with 20% ABV or higher (such as vodka, gin, rum, and whiskey) can be stored in the freezer without freezing solid. However, freezing temperatures can mute the flavors and aromas of these spirits, making them seem flat or dull. Lower-ABV wines, beers, and liqueurs, on the other hand, can freeze and cause the bottle to expand and break.

Therefore, it is important to know the characteristics of different types of spirits and how temperature affects them when deciding whether to store alcohol in freezing temperatures. While chilling certain spirits can enhance the flavor and enjoyment, freezing temperatures can also change the texture and taste of some drinks.

Freezing alcohol can cause bottles to break

Freezing alcohol can be a tricky business, and it is not always advisable. While some spirits can be safely stored in the freezer, others will freeze solid, and even those that don't freeze can be negatively impacted by the low temperatures.

Firstly, it is important to understand that the freezing point of any alcoholic beverage depends on its alcohol by volume (ABV). The lower the ABV, the warmer the freezing point, and the quicker the drink will freeze. This means that drinks with a lower alcohol content, such as beer and wine, will freeze at a higher temperature than hard liquor. Water freezes at 32 degrees Fahrenheit (0 degrees Celsius), and the freezing point of pure ethanol alcohol is a very cold -173 degrees Fahrenheit (-114 degrees Celsius). The average home freezer is around 0 degrees Fahrenheit (-18 degrees Celsius), which is why most hard liquors will not freeze in a home freezer. However, chest freezers can get colder, and there is a chance that even 80-proof liquor will freeze in these conditions.

So, why does this matter? Well, when water freezes, it expands. This means that when you put a drink with a low enough ABV in the freezer, the water content will freeze and expand, which can cause the bottle to expand and break. This is why wines and beers, which are bottled under pressure to maintain freshness and carbonation, can be dangerous to freeze. The corks and caps may swell or rupture, the glass may break, and aluminum cans may explode if stored in freezing temperatures for too long.

Even for drinks that don't freeze, the low temperatures can negatively impact their flavor and texture. Freezing temperatures can mute the flavors and aromas of some drinks, especially those with more subtle flavor profiles, such as whiskey and tequila. This is because the cold temperatures reduce the volatility of the compounds that easily vaporize and contribute to the drink's flavor and aroma.

Beer and wine should not be stored in freezing temperatures

Beer is a living organism in a bottle, and heat promotes the growth of bacteria, leading to unpleasant sour, bitter, or musty flavours. However, extreme cold can also be problematic for beer. Freezing beer can harm its flavour. Ice crystals from the freezer can absorb strange odours, and the extreme cold dulls the beer's flavours. Over-oxygenated beer, which can occur when beer is stored on its side, often tastes like wet cardboard or buttered popcorn.

Wine should also not be stored in freezing temperatures. While wine can be placed in a kitchen refrigerator, it should not be left there for longer than a day or two as the food refrigerator is not ideal for wine. Garages are also not ideal for wine storage as they are subject to big temperature fluctuations. Wine refrigerators are designated appliances that will keep wine safe and in the proper conditions.

Liquors with higher alcohol content can be stored in freezing temperatures, but it is not necessary. Liquors with lower alcohol content will freeze at warmer temperatures.

Spirits with 20% ABV or higher can be stored in the freezer

Spirits with an ABV of 20% or higher, such as vodka, gin, rum, and whisky, can be stored in the freezer without the risk of them freezing solid. This is because the more alcohol a beverage contains, the lower its freezing point. For instance, pure ethanol alcohol freezes at -173°F (-114°C), and beverages with a lower ABV will freeze at a warmer temperature.

Storing spirits in the freezer can enhance the drinking experience. The colder temperature increases the viscosity of the liquid, making it smoother and richer. This can be particularly enjoyable when drinking spirits straight, as the liquid coats the mouth. Chilling spirits can also make them more refreshing, especially in cocktails.

However, it is important to note that while spirits with 20% ABV or higher can be safely stored in the freezer, it may not always be the best option. Freezing temperatures can mute the flavours and aromas of spirits, which is undesirable for drinks with more complex flavour profiles, such as whisky and tequila. For example, some people believe that bourbon and scotch should never be stored in the freezer, as it can be seen as sacrilegious and may alter their flavour profiles.

Additionally, while spirits with high ABV may not freeze solid, they can still undergo undesirable changes when exposed to freezing temperatures over time. For instance, bottles may expand and break, or the seal may be compromised. Therefore, it is important to ensure that bottles are sealed tightly before placing them in the freezer.

In summary, while spirits with 20% ABV or higher can be safely stored in the freezer, the decision to do so depends on personal preference and the desired drinking experience. Some people prefer their spirits chilled, while others may want to preserve the nuanced flavours that can be lost at very low temperatures.
