EVIDENCE-BASED ANSWER
Are Malt and Malt Vinegar Gluten-Free?
Usually no. Malt, malt extract, malt syrup, malt flavoring, and malt vinegar are typically made from barley and are not gluten-free unless a product has been specifically processed and legally labeled gluten-free. Distilled vinegar is different: plain distilled vinegar is generally gluten-free because distillation separates proteins, but flavored products still need checking.

Risk table
| Situation | Risk | Why |

| Flavored vinegar | Variable | Added ingredients require review |
Important exceptions
- Country rules differ for certain hydrolyzed ingredients and gluten-free claims.
- Rice or corn malt exists, but the grain should be explicit and the finished product still needs verification.
What to do
- Search the full ingredient list for “malt.”
- Identify the source grain; unspecified malt is commonly barley.
- Prefer products labeled gluten-free when malt-like flavors are involved.
