Alcohol is a common item that people may leave in their cars, whether intentionally or accidentally. While alcohol can generally withstand temperature fluctuations, extreme heat and direct sunlight can negatively impact its quality and flavour. Additionally, the type of alcohol and the container it is stored in can influence how heat affects it. Beer, wine, and spirits each have varying levels of susceptibility to heat-related damage, with some even posing a safety risk if left in a hot car. Understanding the potential consequences of leaving alcohol in a hot car is essential for both preserving the quality of the beverage and maintaining safety.

What You'll Learn
Beer and sparkling wine can explode
Alcohol does not evaporate when left in a hot car, but it can explode. Beer and sparkling wine are particularly susceptible to exploding when left in a hot car. The extreme heat, coupled with direct sunlight, can cause the internal pressure of the bottles to increase, leading to explosions if the pressure becomes too high. This is more likely to occur with sparkling wines, as the pressure inside a bottle of sparkling wine is somewhere between 70 and 90 pounds per square inch, which is about three times the air pressure inside a car's tires. Beer and sparkling wine are not the only types of alcohol that can be affected by heat. Still wines can also get tainted from being left in a hot environment for too long, and their flavour can be diminished.
The risk of bottles exploding may be higher with lightweight bottles, as producers switch to these from heavier bottles as part of the industry's commitment to sustainability. In addition, beer can turn sour if left in the heat, and the quality and flavour of spirits like bourbon and tequila can also be affected if left in a hot car for a prolonged period.
It is generally recommended to avoid leaving any alcohol in a hot car, especially for extended periods. Aside from the risk of explosion and flavour deterioration, there is also the potential for alcohol to leak and cause damage, as in the case of a woman whose bottle of Prosecco exploded in her car, causing £2,258 of damage.
To prevent alcohol from spoiling or causing damage, it is best to avoid leaving it in a hot car, especially during warm weather. If it is necessary to keep alcohol in a car, it should be for as short a time as possible and stored in a cool, shaded area to minimise the effects of extreme heat and direct sunlight.

Extreme heat diminishes quality and flavour
Extreme heat and direct sunlight can negatively impact the quality and flavour of alcohol. While unopened bottles of pure spirits like vodka are unlikely to be affected by heat, other types of alcohol like beer, sparkling wine, and rum are more susceptible to changes in flavour and alcohol content when exposed to high temperatures.
Beer and sparkling wine are particularly vulnerable to extreme heat, as they can explode if left in a hot car for an extended period. This is due to the build-up of pressure as the carbon dioxide gas escapes from the liquid. Even if they do not explode, the quality and flavour of these beverages will be compromised. Beer can become "skunked," developing an unpleasant taste and odour.
Still wines can also be tainted by excessive heat, resulting in off-flavours and a deterioration in quality. The high temperature can accelerate oxidation and other chemical reactions, altering the delicate balance of flavours and aromas that contribute to the wine's character.
Dark spirits, such as rum, may be more susceptible to heat-induced flavour changes due to the presence of congeners and other flavour compounds. While pure spirits like vodka are primarily ethanol, rum contains sugar and other compounds that can be affected by heat. However, some spirits may be relatively unaffected by heat, especially if they are unopened and stored in a sealed bottle.
Additionally, alcohol with a lower percentage of alcohol by volume, such as beer or wine, may experience a more rapid evaporation of alcohol compared to water when exposed to high temperatures. This can result in a decrease in alcohol content and a change in the overall flavour profile of the beverage.

Spirits are less affected by heat
Spirits are less susceptible to the effects of heat than other alcoholic beverages. Hard liquors like vodka, rum, and whiskey have a high alcohol content and are less likely to be affected by heat if left in a car for a short period of time. This is because spirits are distilled and sealed, making them more resistant to oxidation and changes in flavour.
However, it is important to note that while spirits may be less affected by heat in the short term, prolonged exposure to extreme temperatures and direct sunlight can still impact their quality. Spirits with lower alcohol content or additional ingredients, such as cane sugar mash in rum, may be more susceptible to heat-related changes.
Additionally, the amount of airspace in an opened bottle of liquor can affect the rate of oxidation and evaporation. As alcohol evaporates faster than water, the beverage may gradually become weaker over time. Therefore, it is recommended to decant spirits into smaller containers to minimize airspace and reduce the potential for quality degradation.
While spirits may be relatively stable when exposed to moderate heat for brief periods, it is generally advisable to store them in a cool, dark place to maintain optimal flavour and longevity. Extreme temperatures can affect the integrity of the liquid, and direct sunlight can accelerate the oxidation process, potentially altering the taste and quality of the spirit.
In summary, while spirits are less affected by heat compared to other alcoholic beverages, it is still recommended to store them properly and avoid prolonged exposure to extreme temperatures to ensure their quality and integrity. Taking precautions, such as minimizing airspace in opened bottles and avoiding direct sunlight, can help preserve the intended characteristics of the spirit.

Direct sunlight and high temperatures are bad
Firstly, alcohol does indeed evaporate faster than water, so it will slowly get weaker as it evaporates. The rate of evaporation is dependent on the current temperature, so higher temperatures will result in faster evaporation. This means that even if the alcohol does not reach its boiling point, the alcohol content will be affected.
Secondly, extreme heat and direct sunlight can diminish the quality and/or flavour of the alcohol. This is especially true for beer and sparkling wine, which can explode if exposed to high temperatures for too long. Still wines can also be tainted by excessive heat. While spirits are not as affected as beer or wine, it is still recommended to avoid leaving them in a hot car for extended periods to preserve their quality.
Additionally, high temperatures can cause the pressure inside the container to build up, leading to a potential explosion. This is more likely to occur with open containers, as the alcohol has an escape route, but it can also happen with sealed containers if the temperature gets extremely high.
Moreover, direct sunlight can cause the interior of a car to become significantly hotter than the outside temperature, creating a hostile environment for alcohol storage. This is exacerbated by the glass factor, where sunlight passes through the glass and heats up the car's interior.
Finally, other items commonly left in cars, such as plastic sunglasses, credit/debit cards, and latex items, can be damaged or deformed by high temperatures. Therefore, it is advisable to avoid leaving alcohol and other heat-sensitive items in a car exposed to direct sunlight and high temperatures.

Alcohol in a sealed container may break it
Alcohol in a sealed container may break due to the buildup of pressure. When alcohol is heated, the vapor pressure increases, and if the container is sealed, the pressure can build up to the point where it breaks the container. The higher the temperature, the higher the vapor pressure, and the greater the potential for container breakage.
It is important to note that the effect of heat on alcohol depends on various factors, including the type of alcohol, the temperature, and the presence of oxygen. Hard liquors, such as vodka and rum, are less likely to be significantly affected by heat if they are unopened and sealed. On the other hand, beer, wine, and sparkling wine are more susceptible to heat damage and can even explode if left in a hot car for too long.
To minimize the risk of alcohol breaking its container due to heat, it is recommended to store it in a relatively cool and dark place. Exposure to direct sunlight and high temperatures can affect the quality and flavor of the alcohol. Additionally, for partially consumed bottles, transferring the alcohol to a smaller container can help reduce the airspace and slow down oxidation and evaporation.
While it may be tempting to leave alcohol in a hot car, it is generally not advisable. The extreme heat and direct sunlight can diminish the quality and flavor of the beverage. Additionally, the high temperatures can increase the vapor pressure, leading to a potential safety hazard if the container breaks or explodes due to pressure buildup.
Therefore, it is crucial to prioritize proper storage conditions for alcohol to maintain its integrity and safety. By storing alcohol in a cool, dark place and avoiding extreme temperature fluctuations, you can prevent potential issues and ensure the longevity of your beverage.
