- Check imports — UK products more likely to use malt vinegar
- Spirit vinegar/distilled — Safe alternatives
Beer and Ale
Obvious gluten source:
- Beer mustard — Contains barley
- Ale mustard — Contains barley
- Pub-style mustards — Often made with beer
Mustard at Restaurants

Restaurant mustard is usually:
- Major brand (French’s, Heinz)
- Served in packets — Same as retail

Potential Concerns
- House-made mustard — Unknown ingredients
- Beer mustard — Common at gastropubs
- Pretzel accompaniments — May be beer-based
- Cross-contact — Shared utensils with bread service
Questions to Ask
For house-made mustard:
- “Does this contain beer or ale?”
- “Is there wheat flour in the recipe?”
- “What type of vinegar is used?”
