Is scotch gluten-free?
No scotch can be labelled gluten-free. Single malt is by definition made from malted barley, which is a gluten grain, and blends add wheat or corn grain whisky on top. Distillation removes the gluten protein, so most coeliacs tolerate scotch, but the claim is not available to it.

"Not by label" means the spirit is made from a gluten grain, so US rules bar the claim. It does not mean gluten was detected.
Why that is the answer
Barley is the whole point of scotch, so unlike vodka there is no gluten-free version hiding at the other end of the category. Every single malt starts as malted barley; blended scotch adds grain whisky, usually wheat or corn, without helping. Cask ageing adds nothing gluten-related either way. The chemistry position is the same as for every distilled spirit, the protein does not carry over, and the labelling position is the same too, which is that it cannot say so.
FAQ
Is scotch gluten-free? ▾
Not by label. Malted barley is a gluten grain and it is the defining ingredient of scotch. Distillation removes the gluten protein, and coeliac organisations consider distilled spirits safe, but no scotch can carry the claim.
Is single malt safer than blended scotch for gluten? ▾
No. Single malt is barley only, blends add wheat or corn grain whisky, and both are distilled. Neither can carry a gluten-free label and both remove the protein the same way.
Informational only, not medical advice. If you have coeliac disease, your own tolerance matters more than any label.
