Are Spirits Gluten-Free? | Whisky, Gin, Vodka Explained
Yes, most spirits are gluten-free. Discover how distillation removes gluten and what to watch for in flavoured spirits and liqueurs.
Are Spirits Gluten-Free?
Short answer: Yes. Most spirits are gluten-free.
Distillation removes gluten proteins, even when spirits are made from wheat, barley, or rye.
Properly distilled spirits are gluten-free, even when they are made from grains like wheat, barley, or rye.
This can sound counterintuitive at first. If whisky is made from barley, or vodka from wheat, how can the final product contain no gluten? The answer lies in how distillation works on a chemical level. If you want to dive deeper into that, go to this article.
Why Distillation Removes Gluten
At Copenhagen Distillery, we work with distillation daily, and the separation of alcohol from proteins like gluten is a fundamental part of the process.
Gluten is a large, complex protein found in grains such as wheat, barley, and rye. It is responsible for structure in baking, but it behaves very differently from alcohol during distillation.
Distillation is a physical separation process based on boiling points:
- Alcohol evaporates at a lower temperature than water
- The alcohol vapour rises through the still
- The vapour is cooled and condensed back into liquid spirit
Gluten, however, does not evaporate. It is far too large and heavy to become part of the vapour. Instead, it remains behind in the still along with other non-volatile compounds.
In simple terms:
Only the alcohol and certain flavour compounds make it through distillation — not proteins like gluten.
What This Means for Different Spirits
Because of this process, most traditional distilled spirits are considered gluten-free, regardless of their raw ingredients:
- Whisky → gluten-free after distillation, even when made from barley or rye
- Gin → gluten-free, as it is distilled from a neutral spirit and infused with botanicals
- Vodka → gluten-free, whether made from grain, potatoes, or other sources
- Aquavit → gluten-free, despite often being grain-based before distillation
From a scientific standpoint, the origin grain does not matter once distillation is complete.
Are There Any Exceptions?
Yes, but they occur after distillation, not during it.
Gluten can be introduced if ingredients are added later in the process. This is most common in:
- Flavoured spirits
- Liqueurs
- Pre-mixed cocktails
These products may contain:
- flavourings derived from grains
- colouring agents
- sweeteners or additives that include gluten
For this reason, if you are sensitive to gluten, it is always worth checking the label on flavoured products.
What About Coeliac Disease?
Most health authorities agree that properly distilled spirits are safe for people with coeliac disease, because they do not contain detectable gluten proteins.
However, individual tolerance can vary. Some people prefer to choose spirits made from non-gluten sources (such as potato vodka) for peace of mind, even though the distillation process itself removes gluten.
If you have coeliac disease or severe gluten intolerance, it is always a good idea to:
- stick to pure, unflavoured spirits
- avoid unknown additives
- consult your healthcare provider if unsure
Final Answer
Distilled spirits are gluten-free because gluten cannot pass through the distillation process.
Even when a spirit is made from wheat, barley, or rye, the final product does not contain gluten, as long as nothing is added afterwards.

Frequently Asked Questions
Is whisky gluten-free?
Yes. Although whisky is made from grains like barley or rye, the distillation process removes gluten proteins.
Is gin gluten-free?
Yes. Gin starts as a distilled neutral spirit and is therefore gluten-free before botanicals are added.
Is vodka gluten-free?
Yes. Vodka is gluten-free after distillation, regardless of whether it is made from grain or potatoes.
Can people with coeliac disease drink spirits?
Most distilled spirits are considered safe, but individual tolerance varies. It is best to choose pure, unflavoured spirits and check labels carefully.
Are flavoured spirits gluten-free?
Not always. Gluten can be introduced through added flavourings or ingredients after distillation.
