Treat your group to an outing that is out of the ordinary!
At La Maison de la Moutarde, schools, associations, clubs and groups of all kinds discover the secrets of a century-old Belgian brand in a setting that is playful, gourmet and authentic.
Children and adults travel back in time through the history of Bister, marvel at the objects and anecdotes that have marked more than a century of production, then watch the fascinating ballet of our grenade jars live on the production line. A lively visit that awakens curiosity, taste buds… and memories.

For teachers, it is an opportunity to offer their pupils an original school trip. The visit combines history, geography, science and sensory discovery, giving teachers rich educational links to extend and deepen the experience in class.
For other groups, it is a friendly interlude at the heart of a Walloon flagship, to be shared with friends or fellow enthusiasts.
And to extend the pleasure, several à la carte options allow you to create the visit that suits you best.
