The distillation stills are the stars that every whisky lover looks up to. But there's one thing on the stills that is a silent power: the helmet. Discover in this How to whisky what this really is and why the helmet is so important.

FAQ

What is the helmet of a still?
This is the head that adorns many stills.

Why is the shape of the helmet essential for your distillate?
The shape determines how much copper contact there is, and that affects the taste and character of the spirit.

Why is the helmet made of copper?
A helmet or head is usually made of copper because it makes the spirit purer.

The silent power of distillers

Step into a distillery and your eye immediately falls on the huge copper colossi from which the spirit flows daily: the stills. They are the stars of the distillery. This is where master distillers and their teams conjure up the most exceptional distillates.

Atop the still, there is often a component called the 'lamp glass' or 'helmet.' It is usually an onion-shaped or conical head, and its form can vary greatly. Inside this helmet, extraordinary processes take place that are responsible for much of the spirit’s character.

If you thought the cask had a big influence on the spirit, you haven't discovered the power of the helmet yet.

What does the helmet of a distilling still do?

The helmet that crowns the still is where alcohol vapors collect. When the still is heated, vapors rise and eventually begin to cool. As they recondense, they pass into the copper helmet.

Then a bit of magic happens, thanks to the helmet’s properties. The helmet removes unwanted impurities from the vapor, breaks down sulfur compounds, and ensures that only the finest aromas, scents, and flavors make it through.

A new helmet means a new taste profile

How intensely the helmet works depends entirely on its shape and how much copper contact the spirit has. The more copper contact, the softer and purer the resulting flavor.

Because the helmet’s shape and copper contact have such a decisive influence on the taste of the distillate, choosing the right still is crucial if you want to distill whisky (or any other spirit) yourself.
