Why distilled vinegar is gluten free
Vinegars are made by fermenting alcohol from a starting material (corn, fruit, wine, grain, etc.) into acetic acid. Distillation physically separates the lower-boiling acetic acid and water from larger molecules — including gluten proteins. The final distilled vinegar is below 20 ppm gluten regardless of starting source.
This is why the FDA, the Celiac Disease Foundation, and Beyond Celiac all classify distilled vinegars as gluten free.

- Worcestershire sauce — Lea & Perrins U.S. is now GF (distilled vinegar), but UK formulations vary
- Pickled onions, pickles (UK style) — frequently use malt vinegar
