The art of alcohol distillation | Nedstar

Distillation combines scientific understanding with refined skills, balancing precision with creativity to reach excellence. By using the differences in boiling points of various liquids, this process creates pure ethanol, which is fundamental in the production of alcoholic beverages and is widely used in industries ranging from pharmaceuticals to fuel production. Read on to learn more about distillation and its place in alcohol production.

What is distillation? 

Distillation is a process that separates the components of a liquid mixture based on their different boiling points. When a mixture is heated, the component with the lower boiling point vaporises first. This vapour is then extracted, cooled and condensed back into a liquid form, effectively separating it from the rest of the mixture. This method is particularly effective for separating chemical substances that have distinct boiling points. 

The basic principles of alcohol distillation

The fundamental concept behind alcohol distillation is the difference in boiling points of ethanol (78.37°C) and water (100°C). As the liquid mixture heats up, ethanol vaporises first and is directed to a cooling column to condense and separate. To increase alcohol purity and remove impurities, the distilled liquid undergoes additional distillation cycles.

Distillation over time

Distillation, dating back to ancient times for perfumes and medicines, is now essential across industries. In alcohol production, it separates ethanol from a fermented mixture to create spirits like whiskey, vodka, and rum. Beyond beverages, it's vital in pharmaceuticals, industry, and cosmetics for purification.

Key terms in alcohol distillation

1. Boiling point: The temperature at which a liquid turns into vapour.

2. Vapour pressure: The pressure exerted by a vapour in equilibrium with its liquid at a given temperature.

3. Condensation: The process of a gas turning back into a liquid when cooled. 

4. Separation of components: The isolation of different substances based on their boiling points.

Types of distillation used in alcohol production 

Different types of distillation methods are used in alcohol production, each suited to specific needs and desired outcomes. The three main types are:

The step-by-step process of producing alcohol

The alcohol production process involves several steps outside of distillation, each critical to the final ethanol quality.

Distillation – balancing science and artisanry 

The distillation of alcohol is a sophisticated process that combines scientific principles with artisanal skills, requiring a deep understanding of physical principles and meticulous attention to detail. The process involves careful control of temperature and pressure to achieve the desired separation of components. However, the artistry comes in perfecting the flavour, aroma, and quality of the final product, making it a cherished skill in the production of alcoholic beverages. 

At Nedstar, we recognise the complexity behind every distilled spirit and appreciate the dedication required to master this process. If you want to learn more about the production of ethanol, make sure to read our other blog post on how alcohol is produced.
