In steam distillation, water or another liquid is heated and the steam cools and condenses into a clean liquid. The devices can be found in many places, such as homes because they can be used for cooking, cleaning and sterilizing.
In this guide, I’ll show you how to do steam distillation yourself, step by step and with two different methods: the stirring method or the continuous method.
Types of Steam Distillation
To start the distillation process, you need steam. The Steam Distillation Lab for Beginners offers a simple method using a pressure cooker. However, there are also several ways to create steam. For example, in a hot tub, you can add hot water and condense the steam into liquid form. If you have a steam sauna, hang a collection vessel from the ceiling and add your ingredients.
Now that you have steam, it’s time to choose the distillation method best suited for your needs. The stirring method and the continuous method each offers different benefits.
The Stirring Method
Gently stir the water in your still with a glass rod or similar tool until the vapour condenses into liquid form. Some people prefer to remove any undissolved particles that remain after distillation.
The Continuous Method
The continuous method requires you to stir the water evenly while boiling with a glass rod or other suitable object. The term “continuous” can be interpreted differently, as it refers to stirring at specific intervals or whenever the heat source is active.
Similar to the stirring method, the continuous method uses a small electric fan to blow air over the hot water. This facilitates the cooling and condensation of the water vapour into a liquid state.
Place your container on a hot plate with an electric heating element or use a stovetop to bring the water to a boil. Ensure the heat source is suitable for your container type and can withstand temperatures of at least 200 degrees Celsius.
Once the water is boiling, carefully place the glass container in the steam distillation apparatus, following the manufacturer’s instructions and using the appropriate amount of distilled water for your device.
Activate the heat source and set the duration required for distillation. As a rule, the boiling state must be maintained for at least four hours or until the distillation process is completed.
When distillation is complete, remove the glass container from the heat source and allow it to cool naturally until it reaches room temperature. Clean your glass apparatus thoroughly.
Examples of steam distillation
You can easily perform steam distillation using common household equipment. Let us look at a few examples:
Simple steam distillation for cooking: Place a large pot on the stove and fill it with water. Heat the water until it boils. When the water boils, steam will rise and bubble up. You can also use this method for cooking. Put your ingredients in a collection vessel and place them in the pot, allowing the steam to pass through and draw out the flavours. Ensure the water boils for at least four hours, and remove the pot as soon as the steam stops.
Steam distillation of herbs: Consider an example using herbs such as sage, rosemary, bay leaves, thyme or other aromatic plants. Take a coffee cup or a small container covered with aluminium foil. Put a mixture of the selected herbs in the container. Fill the remaining space with boiling water and set it aside. Allow the steam to act on the herbs to dissolve their aromatic components.
History of steam distillation
Steam distillation has been used since ancient times, even before the Middle Ages. In ancient civilizations, it was used to extract aromas from wine and perfume.
In the Middle Ages, steam distillation entered European households for cooking purposes. It was also used in medical and chemical processes, including alcohol production and metal purification. It was not until after 1800 that steam distillation became popular again, especially for producing distilled liquids such as water, ethanol, ether and many others.
More recently, steam distillation has been gaining popularity again, especially for household applications. As shown in the previous examples, making your own steam distillation system with readily available equipment and ingredients is straightforward.
The Steam Distillation Lab for Beginners provides instructions for building a steam vessel and other essential elements needed for steam distillation using a pressure cooker.
Cooking with Distilled Water
In cooking, the use of distilled water offers several advantages. Distilled water has a higher boiling point than ordinary tap water, so it never rises above 100 degrees Celsius. This precise temperature control can be an advantage in various cooking techniques.
In addition, distilled water evaporates more quickly than tap water. This characteristic allows for more frequent use in cooking and, when combined with ice cubes, provides effective cooling.
Incorporating distilled water into your culinary efforts can improve precision and provide unique benefits for various dishes.
Advantages and Disadvantages of Steam Distillation
Steam distillation offers several advantages and considerations to keep in mind. Let’s explore them:
- Refreshing Water: Distilled water can be produced at room temperature, providing a refreshing alternative to cold tap water.
- Odorless and Tasteless: Distilled water is free from odour and taste, eliminating the need for additional flavourings.
- Cleaning Purposes: Distilled water is commonly used for cleaning due to its purity.
- Plastic Leaching: There have been concerns about the potential leaching of chemicals from plastic containers into distilled water. While these chemicals are not absorbed into the distillation apparatus, it’s advisable to use plastic containers free from harmful substances and rinse them thoroughly with water before use.
With an understanding of the advantages and considerations, you can select a suitable method and explore the process of distilling water for various purposes.
How to Use Steam Distillation
If you intend to employ steam distillation for cleaning purposes, follow these steps:
- Allow the water to sit in the container overnight.
- Once the waiting period is over, filter the water and fill your containers with sterilized water.
For creating herbal tinctures using steam distillation, follow these instructions:

The process of steam distillation was refined by the
The steam distillation process was refined in the Ottoman Empire in the late 14th and early 15th centuries. Avicenna described the distillation process in his treatise “On the Canon of Medicine.” He suggested using stills made of glass or earthenware, as it was believed that they would produce a higher quality of distilled water and a higher overall output than stills made of clay.
In 1441, Aeneas Silvius Piccolomini, later Pope Pius II, published his book on medicine entitled “De re medica” This book was a compilation of medieval medical techniques that included information on steam distillation.
