When making extracts, such as cannabis tinctures or vanilla extract, alcohol is often used as a solvent to extract desired compounds like cannabinoids and terpenes. However, the alcohol taste can be overpowering, and sometimes you may want to reduce or eliminate it. Evaporating the alcohol can be done through various methods, including heating, vacuum purging, or using cold air. Heating the mixture can speed up the process but may also cause the loss of volatile compounds and desired flavours. Vacuum ovens are effective but expensive, while cold air evaporation using increased airflow can be a simple, cost-effective solution. The evaporation method chosen depends on the desired outcome, available equipment, and safety considerations.

Using a vacuum oven
Prepare the Extract
Before using the vacuum oven, ensure your extract has been prepared and is ready for the evaporation process. This typically involves creating a tincture, which is an extract

Heating the extract at 40°C
When using a vacuum purge kit, it is important to heat the extract at approximately 40°C. This temperature is crucial to effectively evaporate the alcohol without damaging the oil.
It is worth noting that there are other methods to evaporate alcohol from tinctures, such as using a bain-marie or a water bath. Some people opt for a water bath by placing the extract in a mason jar or a Pyrex tray in a water bath at 70-80°C. This method is intended to be used until no more large bubbles of solvent are created.
Additionally, there are cold evaporation methods that do not require heat or vacuum equipment. These methods involve increasing air flow to facilitate evaporation. However, it is important to note that heating the extraction mix in an open or non-pressurized environment may cause volatile compounds to evaporate instead of dissolving into the solvent.

Using a water bath at 70-80°C
Using a water bath is an effective method to evaporate alcohol when making extracts. This technique is often employed to remove alcohol from heat-sensitive ingredients that could be damaged or negatively impacted by higher temperatures.
To set up a water bath, you'll need a large pot and a smaller heat-resistant container that can comfortably fit inside it. Fill the large pot with water and place it on the stove. Adjust the temperature to reach a steady simmer. The smaller container, which should be large enough to hold your extract, will be placed inside the larger pot. This setup allows for indirect heating, ensuring a gentler cooking process.
For your specific application, set the water bath temperature to 70-80°C. Place your extract in the smaller container and submerge it in the water bath. Stir the extract continuously to promote even heating and evaporation.
Maintaining a temperature between 70-80°C is crucial. Temperatures above this range may damage your extract or cause it to burn, while lower temperatures will result in slower evaporation. Adjust the stove temperature as needed to maintain the desired range.
The evaporation process can take some time, depending on the volume of your extract and the concentration of alcohol you aim to achieve. Regularly monitor the temperature to ensure it remains within the target range, and continue stirring to facilitate even evaporation.

Simmering alcohol
Alcohol can be evaporated by simmering it at temperatures above absolute zero. The boiling point of alcohol is 78.3°C (173.1°F) and it can be simmered for 15-20 minutes to allow some alcohol to evaporate without significantly harming the flavour. According to a study by the U.S. Department of Agriculture's Nutrient Data Laboratory, simmering alcohol in a mixture for 15 minutes can result in approximately 40% alcohol retention.
When creating extracts, the type of plant used will determine whether heat is an effective method for speeding up the extraction process. For plants with a concentrated flavour, such as vanilla and mint, heat is not necessary as the concentration obtained through a simple cold extraction is sufficient for flavouring a dish. For other plants with less concentrated flavours, such as cherries, heat can be used to speed up the extraction process, but it will not extract more flavour.
To create an extract, the plant material can be combined with alcohol in a jar and left to infuse for a period of time. The alcohol can then be simmered to evaporate some of the alcohol content and concentrate the flavours. This process can be repeated until the desired concentration is achieved.

Using a crockpot
Firstly, the type of alcohol and its initial alcohol content will impact how much evaporates. Alcohol with a higher alcohol content will evaporate faster, as long as it reaches temperatures over the boiling point of alcohol, which is 173°F (78°C). It is important to use a cooking thermometer to monitor the temperature and ensure it reaches the required level.
The design of the crockpot and the cooking method can also affect evaporation rates. Crockpots with lids will retain more alcohol as it condenses on the lid and drips back into the dish. Therefore, it is recommended to cook with the lid off to allow the alcohol vapours to escape. Additionally, using a larger crockpot with a bigger surface area will promote evaporation, as will stirring the mixture during cooking.
The cooking time is another critical factor. The longer the dish is cooked at or above the boiling point of alcohol, the more alcohol will evaporate. For example, stews that simmer for around two and a half hours retain about 5% of alcohol, while bread crumb toppings on scallops cooked in wine sauce can prevent alcohol from evaporating, resulting in higher alcohol content in the final dish.
It is worth noting that the presence of other ingredients can also influence evaporation rates. Some ingredients, like bread crumb toppings, can hinder evaporation, while others may have no significant effect. It is important to research the specific interaction between alcohol and each ingredient in your extract.
Finally, safety considerations are crucial when using a crockpot to evaporate alcohol. Always ensure the area is well-ventilated to prevent the build-up of flammable alcohol vapours. Additionally, be mindful that even after cooking, some alcohol may remain in the extract. This is important information for individuals in recovery, pregnant or breastfeeding women, and those who abstain from alcohol for any reason.

Frequently asked questions
Alcohol will evaporate at any temperature above absolute zero. However, the boiling point of alcohol is 78°C. There are several ways to evaporate alcohol, including:
- Using a vacuum oven or vacuum purge kit.
- Placing a mason jar containing the extract in a bean pot full of water.
- Using a crockpot.
- Using a hot plate with a low voltage, extremely low heat setting.
- Using a home vacuum extraction device.
- Using cold air.
Heating the extraction mix in an open/non-pressurized environment can cause the volatile compounds to evaporate instead of going into the solution.
You can dilute the extract with food-grade glycerin, honey, or LorAnn flavour drops.
You can substitute alcohol with a mixture of food-grade glycerin and water at a ratio of 3:1. However, this method will take longer to infuse and won't provide the same flavour profiles.
