Types of Alembic Stills
Traditional Alembic Still
Traditional alembic stills, often made from copper, are known for their aesthetic appeal and historical significance. They are primarily used for distilling spirits and are characterized by their pot design, which allows for a more complex flavor profile in the final product.
Stainless Steel Alembic Still
These stills are increasingly popular for both essential oil extraction and alcohol production. Their stainless steel construction offers durability and ease of cleaning while providing a sterile environment crucial for essential oil distillation. Their design often includes features like built-in thermometers and cooling connections.
Glass Alembic Still
Glass alembic stills are primarily utilized in laboratory settings. Made from borosilicate glass, they allow for easy observation of the distillation process, making them ideal for educational purposes. They require additional components for complete functionality, including heating mantles and clamps.
Armagnac Type Still
This type of still is tailored for continuous distillation processes, particularly for wines. It features a double boiler system that allows for efficient heating and a consistent flow of the liquid being distilled. This design is essential for large-scale distillation operations.
Applications of Alembic Stills
Alembic stills serve various applications across different fields:
- Distilling Spirits: Traditional and stainless steel alembic stills are widely used in the production of spirits such as whiskey, gin, and vodka.
- Essential Oil Extraction: Stainless steel and traditional models are ideal for extracting essential oils from plants, providing high-quality oils for cosmetics and aromatherapy.
- Laboratory Research: Glass alembic stills are employed in academic and research settings to demonstrate distillation principles and conduct experiments.

FAQ
What is a glass alembic still?
A glass alembic still is a distillation apparatus made from borosilicate glass, designed for laboratory use. It allows for observation during the distillation process and is often used in educational settings.
How does a glass alembic still work?
A glass alembic still operates by heating a liquid mixture to create vapor, which then rises through the apparatus. As the vapor cools, it condenses back into a liquid, which is collected as the distillate.
What is the difference between copper and glass alembic stills?
Copper alembic stills are traditionally used for distilling spirits and have excellent thermal conductivity. Glass alembic stills are primarily used in laboratories for educational purposes and allow for visibility during distillation.
Can a glass alembic still be used for distilling alcohol?
While technically possible, glass alembic stills are not commonly used for distilling alcohol due to their fragility. Stainless steel or copper stills are preferred for this purpose.
What are the typical capacities of glass alembic stills?
Glass alembic stills typically have capacities ranging from 1L to 5L, making them suitable for small-scale distillation experiments.
Are spare parts available for glass alembic stills?
Yes, spare parts for glass alembic stills are usually available and can include components like joints, flasks, and thermometers.
What materials are used in making alembic stills?
Alembic stills are commonly made from materials such as copper, stainless steel, and borosilicate glass, each suited for different distillation applications.
What is the historical significance of alembic stills?
Alembic stills have a rich history, dating back to ancient Greek and Arabic civilizations, where they were used for distilling various liquids, including essential oils and spirits.
How do I clean a glass alembic still?
Cleaning a glass alembic still involves careful handling to avoid breakage. It can be cleaned using warm soapy water and a soft brush, ensuring all parts are thoroughly rinsed.
Where can I purchase a glass alembic still?
Glass alembic stills can be purchased from various online retailers specializing in distillation equipment, including laboratory supply companies and distilling equipment manufacturers.
