Is Whiskey Gluten-Free?
Quick Answer
Distilled whiskey is considered gluten-free by the FDA because distillation removes gluten proteins. However, some celiacs report reactions to grain-based whiskeys.
The Bottom Line: Whether whiskey is gluten-free depends on the specific brand and preparation. Some versions contain gluten while others are safe.

Distilled whiskey is gluten-free under FDA rules, but labels must specify if it was distilled from grains.
In the US, the FDA allows distilled spirits made from gluten grains to be labeled gluten-free because distillation removes proteins. However, the TTB regulates alcohol labels and requires specific disclosures.

The Full Answer
Whiskey (bourbon, scotch, rye, Irish whiskey) is made from gluten-containing grains — barley, wheat, rye, or corn. However, the distillation process is designed to separate alcohol from proteins, including gluten.
The FDA and most celiac organizations consider properly distilled spirits to be gluten-free, regardless of the grain source. The Celiac Disease Foundation states that distilled spirits are safe for most people with celiac disease.
That said, some celiacs report symptoms after drinking grain-based whiskeys, and some experts suggest this could be from trace proteins surviving distillation or from added flavoring after distillation. If you're sensitive, choose whiskeys made from corn (most bourbons are 51%+ corn) or try potato-based vodka instead.
