Last Updated on March 10, 2024 by Lydia Martin

Having your favorite vodka at home can come in handy if you fancy a drink. However, what would happen to a bottle of vodka if it was left open? Aside from a possible change in flavor, does vodka evaporate?

Our team did some researching for 72 hours to get the answer.

Vodka: Does It Evaporate? 


Yes, vodka evaporates. Vodka is a distilled spirit that has varieties stronger than ethyl alcohol. Similar to how other types of alcohol, vodka goes through the process of evaporation [1]. 

Some say that as long as it stays unopened, contents inside remain as it is. However, that can be untrue. Temperature can contribute highly to the state of alcohol. 

All components will remain if the liquor is kept in a stable and cool area. But, if this is exposed to sunlight, the alcohol will evaporate.

At Room Temperature

An opened bottle of vodka stored at room temperature may last for weeks or even months or years. This depends on how carefully you store it. 

You must ensure that it is in a clean container with little air. It must also be covered securely and tightly, standing upright. 

In The Sun

Vodka exposed to the sun will not take long before it evaporates. The longest wait would be 30 minutes at least. 

The flavor will also change when the alcohol evaporates. Apart from evaporation, oxidation [2] will also exist, affecting the savor of the drink.

At Room Temperature

Storing an unopened vodka bottle at room temperature will allow it to last a long shelf life. It is indefinite, but it can last for years if kept cool and dry. An advisable temperature would be between 41-61°F. But is vodka flammable?

In The Sun

The heat that is higher than 61°F will affect its shelf life. However, the vodka is not going to evaporate fast. 

It may take years before the alcohol evaporates since it is still sealed. But, there are instances wherein taste changes, especially if the vodka is a flavored variety.

When Used In Cooking

Cooking with vodka is used in many recipes. However, the alcohol present diminishes depending on the time it is cooked. 

For example, vodka cooked around 15 minutes leaves 40 percent alcohol. After another 15 minutes, only 35 percent remains.

Does vodka evaporate completely?

Yes, vodka evaporates completely. Suppose you leave the bottle open and under the heat of the sun. It will also evaporate completely under a temperature higher than 61°F. 

Does alcohol in vodka evaporate?

Yes, alcohol in vodka evaporates. The main reason this happens is because of high temperature. In time, all alcohol content will evaporate. The sooner it will happen if the bottle remains open.

Does heat evaporate vodka?

Yes, the heat evaporates vodka. A bottle of vodka contains mostly alcohol. Some even reach up to 192 vodka proof or 96 percent. The longer it stays exposed to heat, the faster evaporation happens. 

Does alcohol evaporate if bottle is left open?

Yes, alcohol does evaporate if the bottle is left open. When a bottle of alcohol is left open, the ethanol molecules within the liquid gradually transition from a liquid to a gaseous state, a process known as evaporation. The rate of evaporation depends on several factors, such as the ambient temperature, humidity, and the alcohol content of the beverage. Higher temperatures generally accelerate evaporation, while lower humidity levels promote a faster evaporation process.

The evaporation of alcohol is a physical process that occurs at the liquid’s surface, where molecules gain enough energy to break their bonds and turn into vapor. Over time, the alcohol content of the open bottle diminishes as a result of this phenomenon. It’s important to note that while alcohol evaporates, other components in the beverage may remain, altering the flavor profile. Consequently, storing alcoholic beverages in a sealed container and in a cool, dark place can help mitigate evaporation and preserve the drink’s intended characteristics for a longer period.

How long does alcohol evaporate?

The rate at which alcohol evaporates depends on various factors such as temperature, humidity, and the specific type of alcohol. Generally, alcohol begins to evaporate as soon as it is exposed to air. In a controlled environment with standard conditions, the evaporation process can take anywhere from a few minutes to several hours.

Warmer temperatures typically expedite the evaporation of alcohol, as the heat provides the necessary energy for the molecules to transition from liquid to vapor. Conversely, lower temperatures may slow down the evaporation process. Additionally, higher alcohol concentrations often result in a faster evaporation rate.

Humidity also plays a role, with drier conditions facilitating quicker evaporation. In a humid environment, the air is already saturated with moisture, making it more challenging for alcohol molecules to escape into the air.

It’s important to note that alcohol does not evaporate completely instantaneously, and the time frame can vary based on the specific circumstances. Factors such as the surface area exposed to air, the shape of the container, and the initial volume of alcohol in question also contribute to the overall evaporation duration.

How long does it take for vodka to evaporate when cooking?

The evaporation of vodka during cooking is influenced by factors like heat, surface area, and duration of exposure. Vodka has a lower boiling point than water at 173 degrees Fahrenheit (78.4 degrees Celsius), allowing it to evaporate relatively quickly when subjected to heat. The cooking temperature and duration determine the rate at which the alcohol dissipates.

In the initial stages of cooking, alcohol evaporates rapidly, and within a few minutes, a significant portion may be lost. However, complete evaporation depends on factors like the cooking method, vessel size, and the specific recipe. Simmering or boiling a dish contributes to a faster alcohol evaporation rate compared to baking, where the process is more gradual.

While a significant portion of alcohol can evaporate during cooking, it’s essential to note that trace amounts may still remain, even after prolonged heating. Techniques like flambéing, where alcohol is ignited, can accelerate evaporation but may not eliminate it entirely. Ultimately, the goal is to enhance flavors without preserving the alcoholic content. Adjusting cooking times and methods can help control the retention or reduction of alcohol in the final dish based on personal preferences and dietary considerations

Does 100% alcohol evaporate?

Yes, 100% alcohol, also known as pure ethanol, can evaporate. Evaporation is a physical process where liquid molecules gain enough energy to transition into a gaseous state. In the case of 100% alcohol, with no water content, the evaporation process is straightforward. Since ethanol has a relatively low boiling point of 173.1 degrees Fahrenheit (78.4 degrees Celsius), it can evaporate readily even at room temperature.

The absence of water in 100% alcohol eliminates the complication of water’s higher boiling point. As the temperature increases, the alcohol molecules gain energy, and eventually, they break free from the liquid state and turn into vapor.

It’s important to note that the evaporation of 100% alcohol is rapid compared to solutions with lower alcohol concentrations. However, environmental factors such as temperature, air circulation, and humidity can still influence the speed of evaporation. Additionally, the high volatility of pure alcohol makes it a useful substance for various applications, including cleaning, disinfection, and certain industrial processes, where rapid evaporation is advantageous.

Is vodka still good if left open?

Leaving vodka open can lead to changes in its quality over time, affecting its taste and aroma. Vodka is a distilled spirit with a relatively high alcohol content, which helps preserve it to some extent. However, exposure to air allows for gradual oxidation and evaporation of volatile compounds, potentially altering the original characteristics of the spirit.

While vodka is less prone to spoilage compared to lower-alcohol beverages, an open bottle may be susceptible to changes in flavor and aroma. The rate of these changes depends on factors such as ambient temperature, light exposure, and the duration of the bottle being left open. High temperatures and prolonged exposure to air can accelerate the oxidation and evaporation processes.

Generally, if vodka is left open for an extended period, its flavor may become milder, and subtle notes could diminish. To maintain the original quality, it’s advisable to store an opened bottle of vodka in a cool, dark place and preferably in an airtight container. While the alcohol content acts as a preservative, it’s best to consume vodka within a reasonable timeframe after opening to enjoy it at its peak flavor

Does vodka lose its potency if left open?

Yes, vodka can lose some of its potency if left open for an extended period. The potency of vodka is primarily attributed to its alcohol content, usually around 40% by volume. When a bottle of vodka is left open, it becomes exposed to air, which can lead to gradual evaporation. The alcohol molecules, being volatile, can escape into the air, causing a reduction in alcohol content over time.

The rate at which vodka loses potency depends on various factors such as ambient temperature, humidity, and the duration of exposure. Higher temperatures and lower humidity levels generally contribute to a faster evaporation process. While vodka has a higher alcohol content compared to many other alcoholic beverages, it is not entirely immune to changes in its composition when exposed to the elements.

To minimize the loss of potency, it is recommended to store open vodka bottles in a cool, dark place and seal them tightly to limit air exposure. Consuming the vodka within a reasonable timeframe after opening will help ensure that it retains its intended strength and flavor profile.

Does liquor alcohol evaporate?

Yes, the alcohol in liquor can evaporate over time when the bottle is left open. Liquor, like vodka, whiskey, or other distilled spirits, contains ethyl alcohol, which is volatile and can transition from liquid to vapor when exposed to air. The rate of alcohol evaporation in liquor is influenced by factors such as temperature, humidity, and the specific composition of the beverage.

Higher temperatures can accelerate the evaporation process, and in drier conditions, alcohol tends to evaporate more quickly. While the alcohol content in liquor is relatively high, typically ranging from 40% to 50% alcohol by volume, it does not completely prevent evaporation.

Over time, an open bottle of liquor may experience changes in flavor and aroma as a result of the gradual loss of alcohol. To preserve the quality of the liquor, it is advisable to store opened bottles in a cool, dark place and tightly seal them to minimize air exposure. Proper storage conditions can help slow down the evaporation process and extend the period during which the liquor retains its intended characteristics.

Will 70% alcohol evaporate?

Yes, 70% alcohol can and does evaporate. Alcohol, including isopropyl alcohol or rubbing alcohol at a concentration of 70%, is a volatile liquid that readily transitions into a gaseous state when exposed to air. The term “70%” refers to the alcohol concentration, with the remaining 30% typically being water.

The water content in the solution plays a crucial role in controlling the evaporation rate. While high concentrations of alcohol evaporate quickly, a lower concentration, such as 70%, can be more effective in certain applications because it evaporates more slowly. The water in the solution helps to keep the alcohol in contact with surfaces for a more extended period, enhancing its efficacy as a disinfectant or cleaner.

Factors like temperature, humidity, and airflow influence the speed of evaporation. Generally, higher temperatures and lower humidity levels promote faster evaporation. When using 70% alcohol for cleaning or disinfection, it is essential to allow sufficient contact time to ensure its effectiveness, considering both the alcohol and water components will gradually evaporate from the applied surface. Proper storage in sealed containers can also help maintain the intended concentration over time.

Is alcohol easy to evaporate?

Alcohol is relatively easy to evaporate due to its molecular structure and low boiling point. The term “alcohol” commonly refers to ethanol, a type of alcohol found in beverages like vodka. Ethanol molecules have weaker intermolecular forces compared to water, allowing them to transition from a liquid to a gaseous state at lower temperatures.

How do you keep vodka from evaporating?

To prevent vodka from evaporating, proper storage is essential. Keep the bottle tightly sealed to minimize exposure to air, which can accelerate evaporation. Storing vodka in a cool, dark place also helps, as higher temperatures can expedite the process. Additionally, consider using an airtight container or a vacuum-sealed preservation system to further protect the vodka from air and temperature fluctuations.

Does vodka evaporate faster than water?

The rate of vodka evaporation compared to water depends on several factors, including temperature, humidity, and surface area exposed. In general, alcohol evaporates faster than water due to its lower boiling point. However, the presence of water in vodka slows down the process compared to pure ethanol.

What temperature does vodka evaporate?

The temperature at which vodka evaporates is its boiling point, which is around 173.1 degrees Fahrenheit (78.4 degrees Celsius). However, vodka can start to evaporate at lower temperatures, especially in the presence of air and over an extended period. Evaporation rates increase with higher temperatures, making it crucial to store vodka in a cool environment to preserve its quality over time

Does Vodka Evaporate At All?

We all know what happens to alcohol when placed under the sun’s heat. It evaporates. It is definitely going to happen with vodka if you do not secure it. 

An unopened bottle technically has an indefinite life span. This is if you ensure that it is stored somewhere below 61°F. Not all vodkas are alike, by the way. 

Do not assume that they will last for years if properly cared for. Some are with other ingredients that affect its shelf life, apart from the heat. So, if you want to enjoy your bottle of vodka longer, make sure you store it properly.
