Alcohol is a volatile substance, and its molecules will evaporate when it reaches its boiling point of 173 degrees Fahrenheit. However, contrary to popular belief, cooking with alcohol does not cause all of it to evaporate. Factors such as cooking time, temperature, cooking method, and the size of the pan influence the amount of alcohol that remains in a dish. While the remaining alcohol content is typically low and unlikely to cause intoxication, it may still be significant for those avoiding alcohol for health or religious reasons. Thus, it is important to understand how cooking with alcohol affects its presence in food.

What You'll Learn
Alcohol does not fully evaporate when cooked
The U.S. Department of Agriculture (USDA) found that dishes baked or simmered in alcohol retain 40% of the original alcohol content after 15 minutes, 35% after 30 minutes, and 25% after an hour. Even after 2.5 hours, 5% of alcohol remains. The USDA's findings also indicate that the greater the surface area of the dish, the more alcohol is exposed to the air and the faster it will evaporate.
The type of alcohol used also affects the amount of alcohol that remains in a dish. For example, beer cheese sauce, bourbon caramel, and other similar sauces retain about 85% of their alcohol content when brought to a boil and removed from heat. Flambéing, or igniting alcohol-spiked dishes, does not significantly reduce alcohol content either, with one study finding that this method only reduced alcohol content by less than 15%.
The amount of alcohol remaining in a dish after cooking is also dependent on the number of other ingredients in the dish. The more ingredients mixed with alcohol, the harder it is to cook off the alcohol. Additionally, the amount of alcohol in a dish after cooking may be significant for those avoiding alcohol for religious or health reasons. While it is unlikely that dishes cooked with alcohol will cause intoxication, the alcohol does not completely evaporate, and alternatives may be preferable when preparing food for children, pregnant women, or those in recovery.

Factors that influence alcohol evaporation
Alcohol is a volatile substance, and its molecules will evaporate not only when it reaches its boiling point of 173 degrees Fahrenheit but also any time it is exposed to air. However, it is impossible to cook out all the alcohol from a dish. The amount of alcohol that remains depends on several factors, including the recipe's ingredients, the temperature, and the cooking time. Here are some factors that influence alcohol evaporation:
Temperature
The higher the temperature, the quicker alcohol evaporates. Alcohol evaporates at 173 degrees Fahrenheit, which is much lower than water's boiling point of 212 degrees Fahrenheit. Therefore, cooking at higher temperatures will cause more alcohol to evaporate.
Cooking Time
The longer the cooking time, the more alcohol evaporates cumulatively. For example, baking or simmering an alcohol-containing dish for 30 minutes will retain 35% of the original alcohol content, while cooking for an hour will reduce it to 25%. Stews that simmer for 2.5 hours tend to have the lowest amounts, retaining about 5% of alcohol.
Surface Area and Pan Size
A larger surface area allows more alcohol molecules to be exposed to the air, increasing evaporation. Therefore, using a bigger pan or cooking in larger quantities will result in more alcohol evaporation. For instance, a beurre blanc sauce simmered in a large stockpot will have less alcohol than the same sauce cooked in a small saucepan.
Stirring
Recipes that require stirring during the cooking process tend to have lower alcohol retention because stirring promotes evaporation.
Other Ingredients
The other ingredients in the recipe can influence alcohol evaporation. For example, a bread crumb topping on scallops cooked in wine sauce can prevent alcohol from evaporating, resulting in a higher alcohol content in the final dish.
Alcohol Type and ABV
The type of alcohol and its alcohol by volume (ABV) will also impact the final alcohol content of a dish. For instance, when cooked under the same conditions, beer and rum will evaporate at the same rate. However, because beer typically has a lower ABV than rum, a dish made with beer will have a lower alcohol content than one made with rum.
While cooking with alcohol can reduce its content, it is worth noting that complete evaporation of alcohol from a dish is challenging, and alternatives may be preferable when preparing food for children, pregnant women, or those in recovery.

Alcohol content in cooked food is usually insignificant
Alcohol is a volatile substance, and its molecules will evaporate when exposed to air or when it reaches its boiling point of 173 degrees Fahrenheit. However, despite its ability to dissipate, it is impossible to cook out all of the alcohol in a dish. The amount of alcohol that remains depends on various factors, including the recipe's ingredients, cooking temperature, and duration.
While it is true that some alcohol evaporates during the cooking process, it is a misconception that it completely "burns off." Studies have shown that the amount of alcohol remaining after cooking can range from 4% to 95%, depending on the cooking method and duration. For example, baking or simmering dishes containing alcohol for 15 minutes retains 40% of the original alcohol content, 35% after 30 minutes, and 25% after an hour. Even after 2.5 hours, 5% of the alcohol content remains.
The size of the pan also affects the amount of alcohol that evaporates, with larger pans providing more surface area for the alcohol molecules to escape. Additionally, recipes that require stirring during cooking tend to have lower alcohol content due to the stirring action promoting evaporation.
The type of alcohol used also plays a role in the amount of alcohol remaining. For instance, beer cheese sauce, bourbon caramel, and other sauces brought to a boil and then removed from the heat can retain up to 85% of the alcohol content. Flambéing, or igniting alcohol-spiked sauces, may still leave up to 75% of the alcohol content, as the loss of ethanol is due to heating and evaporation rather than combustion. Marinades that are not cooked can retain up to 70% of the added alcohol, while meats and baked goods cooked without stirring for 25 minutes can retain 45%.
While the alcohol content in cooked food is generally considered insignificant in terms of causing intoxication, it can be a concern for individuals who abstain from alcohol for medical, religious, or personal reasons. The amount of alcohol typically used in recipes is usually small, and even if uncooked, it is unlikely to cause intoxication in adults. However, for children, pregnant women, or those in recovery, alternative ingredients or non-alcoholic beverages can be used as substitutes.

Substitutes for alcohol in cooking
Alcohol is a volatile substance, and its molecules will evaporate when exposed to air or when it reaches its boiling point of 173°F. Despite this, it is impossible to cook out all of the alcohol in a dish. The amount of alcohol that remains depends on several factors, including the recipe's ingredients, cooking temperature, and duration. For instance, a larger pot or pan allows more alcohol to evaporate due to increased surface area.
When substituting alcohol in cooking, it is important to consider the purpose it serves in the recipe. Alcohol can enhance flavour by bonding with other ingredients, especially in marinades. Here are some suggestions for substituting alcohol in cooking:
- Wine: Use tomato juice or coffee, especially when substituting for a pinot. Add a small amount of honey or sugar to replicate the sweetness of wine.
- Beer: Use coriander and malt syrup to mimic the flavour of a hoppy beer. In recipes that require carbonation, such as beer-battered dishes, substitute with sparkling water or ginger beer.
- Spirits: Substitute rum with brown sugar and vanilla. For vodka, mix equal parts apple cider and lime juice. For whisky, there is no perfect substitute for its aroma, but a small amount will evaporate quickly, leaving only its fragrance.
- Sake: Use rice vinegar or white grape juice instead of sake.
- Vermouth: Opt for Seedlip botanical distillate or white wine vinegar, although the latter still contains a small amount of residual alcohol.
- Hard cider: Choose a dry non-alcoholic cider, or mix cider vinegar with cider or unsweetened juice for a savoury edge.
- Extracts: Traditional extracts are alcohol-based, but alcohol-free extracts are available from brands like Heilala and Frontier. Alternatively, use flavour or candy oils, but use sparingly as a little goes a long way.

Alcohol is necessary in some dishes
Alcohol is a versatile ingredient that can be used in cooking either as an ingredient, a cooking fuel, or for visual display. Alcohol is frequently used in cooking for its acidic properties, bitter tannins, and fruit components. It can also make dishes smell more appetizing, enhancing the overall dining experience.
There are several dishes that require alcohol to enhance the flavor of the dish. For instance, coq au vin, chicken cacciatore, chicken marsala, and boeuf bourguignon are classic examples of dishes that require wine as an ingredient. Bratwursts boiled in beer, beer grilled chicken, and chili with beer added instead of water are some modern examples of dishes that require alcohol.
Specialist cooking wines, liqueurs, vermouths, and eaux de vie are commonly used by professional chefs to enhance the flavor of traditional and modern dishes. These alcoholic beverages are specially created to be used as ingredients in cooking rather than as a beverage.
Additionally, flambé is a cooking technique that requires alcohol. Flambé involves pouring alcohol, such as brandy, on top of a dish and igniting it to create a visual presentation. This technique is often used in Japanese teppanyaki restaurants, where a spirit is poured onto the griddle and lit, leaving a residue that indicates the hottest parts of the griddle.
While some alcohol does evaporate during the cooking process, it is impossible to cook out all of it. The amount of alcohol that remains depends on various factors, including the recipe's ingredients, cooking temperature, and duration. Therefore, when preparing food for individuals who abstain from alcohol, such as children, pregnant women, or those in recovery, it may be preferable to use alternative ingredients or non-alcoholic substitutes.
