Whether you're leaving your beer outside in the snow or forgetting about it in the freezer, it's all too easy for your beer to freeze without you realising. But can you still drink it? The answer is yes and no. While it's safe to drink a beer that's been frozen and then thawed, it might not taste as good. Freezing affects a beer's flavour, carbonation, and consistency, and can leave it cloudy and flat. However, if the seal hasn't been broken, the beer will likely taste normal once it's returned to room temperature.
What You'll Learn
Is it safe to drink frozen beer?
It is safe to drink beer that has been frozen and then thawed, as long as the seal hasn't broken, allowing carbon dioxide to escape. If the seal is broken, the beer will be flat. Freezing and then thawing beer can cause it to oxidize, which will make it smell stronger and taste stale. In more extreme cases, it could cause the beer to denature, making it unsafe to drink.
If the seal is intact, the beer will taste normal once it is returned to room temperature. This is because the carbonation will go back into solution. However, if you drink the beer before it has completely thawed, you will be drinking almost pure alcohol, as water freezes at a higher temperature than alcohol. This can be dangerous, as it means you are consuming a much higher alcohol content than expected.
To thaw frozen beer, it is recommended to put it in the fridge for 12 to 24 hours. It can also be placed in a bucket of cold water, but warm water should be avoided as this can cause the glass to shatter or the can to burst.

What is the best way to defrost frozen beer?
The best way to defrost frozen beer depends on when you want to drink it. If you want to drink it as soon as possible, place the beer in a bucket of cold water. It is important to ensure that the water is cold, as warm water could cause a temperature shock, potentially causing the glass bottle to shatter or the aluminium can to burst. Depending on how frozen the beer is, this method can take anywhere from a few minutes to an hour.
If you have more time, you can defrost the beer by placing it in the refrigerator for 12 to 24 hours. This method ensures a slow and gradual thawing process, allowing the beer to return to its original state. It is important to note that the time required for the beer to fully defrost will depend on the temperature setting of your fridge.
To prevent a mess in case the beer leaks during the defrosting process, it is recommended to place the beer in a Ziploc bag or container before moving it to the fridge or cold-water bath. Additionally, avoid using hot or warm water to speed up the process, as this can cause the glass to expand too quickly and break.
Once the beer is fully defrosted, it is recommended to keep it in the fridge to allow the CO2 to dissolve back into the beer, improving its taste and carbonation.

Does freezing affect the taste of beer?
Freezing does affect the taste of beer. When beer freezes, its physical properties change, and its flavour, consistency, and carbonation are all impacted. Beer also loses its fizz and becomes flat when frozen.
The beer will taste normal again if you allow it to completely thaw and the seal hasn't been broken. If the seal is broken, the beer will be flat.
If you drink the beer before it's fully thawed, the liquid you drink will be straight alcohol, as water stays frozen longer than alcohol. This will give the beer a stronger flavour and a higher alcohol content.
Even if you allow the beer to fully thaw, the liquids will still be separated unless they're mixed up again. The beer will also have a stronger scent and a stale taste. In more extreme cases, freezing and thawing can cause the beer to denature, making it unsafe to drink.

Can freezing beer increase its alcohol content?
Beer can be frozen, but it is not recommended as it may ruin the quality of the beer and cause the bottle or can to explode. Freezing beer does not remove the alcohol content. In fact, freezing beer is a way to increase the amount of alcohol in your beverage quickly and easily. This process is known as "jacking" or "fractional freezing". Since alcohol does not freeze as fast as water, freezing beer, wine, or apple cider can increase the amount of alcohol in the beverage.
The exact freezing point of any beer depends on its alcohol by volume (ABV). The lower the alcohol content, the warmer the freezing point and the quicker it will freeze. Beer can have an ABV anywhere between 3% and 12%, but on average you can expect beer to freeze at about 28 °F (-1.7 °C).
It is worth noting that freezing beer is illegal in the US if it increases the alcohol content by more than half of one percent. This is because freezing beer is considered a form of distilling, which is illegal for home consumption.
To chill beer quickly without freezing it, you can put the bottles or cans into a bucket of salted ice water. The salt will lower the freezing point of the water, allowing the beer to chill more quickly without freezing.

What is the best way to quickly chill beer without freezing it?
While it's tempting to stick your beer in the freezer to chill it quickly, this can lead to a mess or a ruined drink. So, what's the best way to rapidly cool your beer without this risk?
One tried-and-true method is to submerge your beer in a bucket of ice water and salt. The salt lowers the freezing temperature of the mixture, causing the ice to melt, which in turn lowers the water's temperature and rapidly chills the beer. This method can have your beer chilled in as little as 5 minutes, or around 15 minutes depending on the source.
If you don't have salt to hand, simply submerging the beer in ice water will also work, although it may take a little longer. This method is also effective with chilled water from the fridge, but will be slower again. As a general rule, the more coolant you have relative to the number of beers, the faster the cooling reaction will be.
Another quick method is to wrap your beer in a damp cloth or paper towel and place it in the freezer. As the water on the cloth or towel evaporates, it draws heat away from the beer, resulting in a chilled drink in around 15 minutes.
If you're looking for an even faster solution, you could try using compressed air. Hold a can of compressed air upside down and spray the side of the beer bottle or can for a few seconds until frost forms. Be sure to hold the can upside down, as this makes the air that comes out extra cold. This method can chill your beer in as little as 30 seconds.

Frequently asked questions
Yes, frozen beer is safe to drink. However, it may taste different as freezing can cause the beer to become flat and stale.
To defrost frozen beer, place it in a Ziploc bag or container to avoid a mess in case the beer leaks. Then, put it in a cool place, like a fridge, for 12-24 hours. Do not put it in a warm place as the can or bottle might explode.
Drinking beer while it is still frozen is not recommended. If the beer isn't thawed, the liquid you drink will be straight alcohol, as water stays frozen longer than alcohol.
To chill beer quickly without freezing it, place the bottles or cans in a bucket of salted ice water. Salt lowers the freezing point of water, so the beer will be chilled faster and there is no risk of it freezing.
