Understanding absinthe
What Is Absinthe?
Absinthe is a distilled spirit made from a combination of botanicals, most notably wormwood, anise and fennel. Known for its distinctive aroma and its transformation when diluted with water, absinthe occupies a unique place among spirits.
Originating in the Val-de-Travers in Switzerland, absinthe is defined not only by its ingredients, but also by its method of production and its ritual of preparation.
What Is Absinthe Made Of?
Absinthe is produced through distillation using a base of alcohol and a selection of plants.
The essential botanicals are:
- Wormwood (Artemisia absinthium) — the defining ingredient
- Green anise — contributing sweetness and roundness
- Fennel — adding depth and balance
Additional herbs may include hyssop, melissa or other regional botanicals, depending on the recipe.
The balance of these ingredients determines the character of the absinthe.
How Is Absinthe Made?
Traditional absinthe is made through distillation.
The process typically involves:
- Macerating botanicals in alcohol
- Distilling the mixture to extract aromas
- Optionally macerating additional herbs for colour (in the case of verte absinthe)
This results in a high-proof spirit that is both aromatic and structured.
The method of distillation is central to the definition of absinthe, distinguishing it from products that rely on flavouring or mixing rather than distillation.
Why Does Absinthe Turn Cloudy?
When water is added to absinthe, it becomes milky or cloudy. This effect is known as the louche.
It occurs because essential oils from the botanicals are not soluble in water. As the alcohol content decreases during dilution, these oils are released, creating the characteristic cloudy appearance.
The louche is not only visual — it also reveals the full aromatic profile of the absinthe.
Absinthe Verte and Absinthe Blanche
Absinthe is generally divided into two main styles:
- Absinthe verte — green in colour, obtained through a secondary maceration of herbs after distillation
- Absinthe blanche — clear, bottled directly after distillation without colouring
While both share the same base, they offer different expressions of the spirit.

Where Does Absinthe Come From?
Absinthe originates in the Val-de-Travers, a region in Switzerland where it was first developed and refined.
While the spirit is now produced in various countries, the Val-de-Travers remains its historical centre and a reference point for its production methods and identity.
Understanding this origin is essential to understanding absinthe itself.
How Is Absinthe Traditionally Prepared?
Absinthe is not typically consumed neat.
Instead, it is prepared by slowly adding cold water, often using an absinthe fountain. Sugar may be added depending on preference.
This gradual dilution:
- softens the alcohol
- reveals aromas
- creates the louche
The preparation ritual is an integral part of the absinthe experience.

Is Absinthe Legal?
Absinthe is legal in most countries, although regulations may vary.
Modern absinthe is produced within defined standards, particularly regarding thujone content. These regulations allow for a wide range of styles while maintaining safety and consistency.
