Is Grey Poupon Dijon Mustard Vegan?

For most dietary vegans who rely on ingredient labels, Grey Poupon Dijon reads as vegan: every listed ingredient is plant-derived. The concern is process-level, not ingredient-level.

These agents are filtered out before bottling, so they do not appear on ingredient labels and are not legally required to be declared in the US. The Country Dijon variant (coarse ground) has the same ingredient structure and the same ambiguity.

Grey Poupon Vegan Mayonnaise sold in the UK is a separate product and carries a vegan label, but that designation does not extend to the US Classic Dijon mustard. If you contact Kraft Heinz consumer services, they may confirm or deny, but responses are inconsistent based on community reports.
