Alcohol has a lower boiling point than water, which means it evaporates faster. The molecules in alcohol are less attracted to each other and require less energy to escape into the gas phase. The evaporation rate of alcohol also depends on the temperature, light, heat, and humidity of the environment. When alcohol is heated, some of it evaporates, but around 85% of it survives the heating process. A study by the USDA Nutrient Data Laboratory found that wine can retain up to 5% of its alcohol content even after boiling for 2-3 hours. Similarly, a glass of beer can lose 20-30% of its volume overnight at room temperature due to evaporation.

What You'll Learn
Alcohol has a lower boiling point than water
The boiling point of alcohol varies depending on its type, but ethanol typically boils at 173.1°F (78.3°C) under standard atmospheric pressure. This is lower than the boiling point of water, which is 212°F or 100°C. The higher vapor pressure of alcohol means that it will evaporate more quickly than water, as its molecules require less energy to escape into the gas phase. This is also why distillation is not an effective way to remove alcohol from wine, as the water will begin to evaporate as well, leaving a concentrated and bitter drink.
The different boiling points of alcohol and water can be used to separate them using distillation. In this process, a liquid is carefully heated so that more volatile compounds boil away and can be collected. However, distillation cannot fully separate the two chemicals. This is because alcohol and water form an azeotrope, binding to each other, and cannot be easily separated using heat.
The rate of alcohol evaporation varies based on temperature, light, heat, and humidity. Higher temperatures will cause alcohol to evaporate more quickly. This can be observed when heating alcoholic beverages, where around 85% of the alcohol will survive the heating process. Similarly, a glass of beer with a lower alcohol content left overnight at room temperature can lose 20-30% of its volume.
Storing alcohol in a freezer or fridge can slow down the rate of evaporation. Lower temperatures reduce the energy available for evaporation to occur. However, this is more applicable to high-proof spirits, as lower-proof liqueurs may freeze due to their higher water content.

Storing alcohol in a fridge or freezer can slow evaporation
Alcohol evaporates at a lower temperature than water. Alcohol has a boiling point of 173.1°F (78.3°C), while water boils at 212°F (100°C). This means that alcohol evaporates faster than water. The rate of evaporation depends on factors such as temperature, light, heat, and humidity.
Storing alcohol in a cool place like a fridge or freezer can slow down the evaporation process. Lower temperatures reduce the energy available for evaporation to occur. However, this technique is more effective for high-proof spirits like vodka or rum, as lower-proof liqueurs may freeze due to their higher water content. For example, beer, with its lower alcohol content and higher water content, will evaporate faster at room temperature, especially in a wide-open container. A glass of beer can lose 20-30% of its volume overnight at room temperature. On the other hand, a glass of whiskey, with a higher alcohol content, will evaporate slower, losing about 5% of its volume overnight.
Additionally, storing spirits with complex flavors like rum and whiskey in the freezer for extended periods can dull their aromas and tastes. For common distilled spirits, the recommended storage temperature is around room temperature, with some experts suggesting a slightly cooler range of 55-60°F. Fortified wines, such as vermouth, port, and sherry, along with cream-based liqueurs, should be kept in the fridge.
While decanters can enhance the aesthetic appeal and improve aeration for certain spirits, they are not necessary for proper storage. Some decanters include additional features like vacuum seals or nitrogen purging systems that claim to further reduce evaporation, but their effectiveness may be debatable. The original bottle might be the best option for long-term storage.

Alcohol in hot drinks evaporates, but at a slower rate than water
Alcohol does indeed evaporate, but it does so at a slower rate than water. This is because alcohol has a lower boiling point than water—173.1°F (78.3°C) for alcohol versus 212°F (100°C) for water. This means that alcohol requires less energy for its molecules to escape into the gas phase, resulting in faster evaporation than water.
The rate of evaporation for both alcohol and water can be influenced by factors such as temperature, light, heat, and humidity. For example, a glass of beer with its lower alcohol content (typically 4-7%) and higher water content will evaporate relatively quickly at room temperature, especially if left in a wide-open glass. On the other hand, a glass of high-proof spirits like whiskey, with its higher alcohol content (40% or more), will evaporate slower under the same conditions.
When it comes to hot drinks, the heating process will cause some alcohol to evaporate. However, studies have shown that around 85% of the alcohol will survive the heating process. Boiling alcoholic beverages is not an effective way to remove alcohol, and it can negatively impact the flavour and quality of the drink. For example, boiling wine can result in a concentrated, sour, and more bitter-tasting beverage.
The rate of evaporation for alcohol also depends on the alcohol content and storage conditions. High-proof spirits (40% ABV or higher) like whiskey, vodka, or rum can lose 2-3% of their volume annually when stored properly, while lower-proof bottles (below 25% ABV) like liqueurs can evaporate faster, at a rate of around 5-10% per year. Storing liquor in a cool place, such as a freezer or fridge, can slow down the rate of evaporation, although this may affect the flavour and aroma of certain spirits.

Beer evaporates quickly at room temperature
Alcohol has a lower boiling point than water, with alcohol boiling at 173.1°F (78.3°C) and water boiling at 212°F (100°C). This means that alcohol requires less energy than water to escape into the gas phase, leading to faster evaporation. The rate of evaporation for alcohol is influenced by factors such as temperature, light, heat, and humidity. Higher temperatures generally result in faster evaporation rates.
Beer, with its lower alcohol content (typically 4-7%) and higher water content, will evaporate relatively quickly at room temperature. A glass of beer left out overnight can lose 20-30% of its volume, becoming flat and stale. The evaporation rate is even higher in a wide glass or dry environment. In contrast, high-proof spirits like whiskey, with an alcohol content of 40% or more, will evaporate more slowly under the same conditions.
The evaporation rate of alcohol can also be influenced by the type of container it is stored in. For example, liquor stored in a freezer or fridge can slow down the rate of evaporation as lower temperatures reduce the energy available for evaporation. Plastic bottles create a tighter seal compared to glass bottles with screw caps, resulting in a reduced air gap for alcohol molecules to escape. Additionally, some decanters include features like vacuum seals or nitrogen purging systems that claim to further reduce evaporation, although their effectiveness may be debatable.
It is important to note that even at room temperature, alcohol will eventually evaporate from an open container. However, the rate of evaporation for alcohol at room temperature is relatively slow compared to boiling temperatures. The evaporation rate for ethanol, the type of alcohol found in liquor, can range from 0.02% to 0.19% per day at room temperature.

Alcohol evaporation depends on the cooking method and heat applied
Alcohol evaporation depends on several factors, including the cooking method, the heat applied, and the duration of cooking. The size of the pan and the dish's other ingredients also play a role in the evaporation rate.
Simmering or Boiling
Simmering or boiling alcohol in a mixture, such as a sauce or dessert cream, will result in varying levels of alcohol retention depending on the cooking time. According to a study by the U.S. Department of Agriculture's Nutrient Data Laboratory, simmering or boiling for 15 minutes can leave approximately 40% of alcohol; 30 minutes results in about 35% retention; at one hour, about 25% remains; and at two hours, only about 10%. This applies to cooking sauces, desserts, or marinades that include alcohol.
Baking
Baking with liquor, such as vodka or rum, will also affect alcohol retention. For example, after 15 minutes in an oven set at around 350 degrees Fahrenheit (175 degrees Celsius), the amount of alcohol remaining will be higher than if baked for a longer duration.
Pan Size
The size of the pan used in cooking with alcohol also matters. Smaller pans result in more alcohol remaining in the recipe because they have a smaller surface area for evaporation.
Stirring
Recipes that require stirring during the cooking process tend to have lower alcohol retention because stirring promotes evaporation.
Type of Alcohol
The type of alcohol used in cooking also affects the amount of alcohol that evaporates. Different alcohols have different alcohol by volume (ABV) percentages. For example, beer typically has an ABV range of 3.5% to 9%, while rum usually falls between 40% and 75.5%. When cooked under the same conditions, beer and rum will evaporate at the same rate, but the completed dish will be less alcoholic when made with beer due to its lower ABV.
