In Molenbeek-Saint-Jean, behind a rather understated industrial façade, Didden produces its sauces and condiments from an 8,000 m² site. Beci stepped inside a company that has remained loyal to Brussels since 1925. Immersion.
You don’t visit a sauce factory the way you enter an office. Protective gown on, hairnet in place, shoe covers secured: the hygiene protocol is the first step. The door closes behind us and immediately the spices take over. It tingles slightly in the nose. The smell recalls pickles, the company’s signature product and a key part of its family history.
8,000 m² of precision and flavour
The building, located between Boulevard Mettewie and Place Docteur Schweitzer, impresses more with its 8,000 m² surface area than with its façade. In this former warehouse, entirely redesigned, Didden produces confits, mayonnaise, pickles and dressings. Three areas structure the site: raw materials, production and shipping. Here, the flow of ingredients follows a perfectly orchestrated choreography.
In the workshops, the vats are turning and the filling lines are running. The sauces are created here, jarred, labelled and prepared for shipment to Belgian clients or for export. The packaging is carried out in a protected external workshop before returning to the site for final assembly.
Nothing crosses paths, nothing is mixed by chance. Refrigeration units, production areas and storage zones are carefully compartmentalized. A team of electromechanics ensures that the installations run smoothly, while in a nearby office, quality checks follow one after another. At the slightest variation, everything is verified and adjusted. Then there is the laboratory, calmer, where recipes are tested and refined. Three new sauces are currently under development there. Here, the industrial tool never overshadows taste… nor the scent of spices that lingers in the air.
A family business in the truest sense
The story begins in 1925, when Jean-François Didden founded the company with his sons. At the time, products were sold door-to-door, with Brussels as their playground. The following decades did not spare the family: a death at the beginning of the Second World War, the dioxin crisis in 1999, and more recently the surge in raw material and energy costs. Yet the century-old company endures, adapts and continues to produce.
Some recipes have stood the test of time. Pickles, of course. The “Grand-Mère” mayonnaise, created for Expo 58, is still produced using the traditional mixer-emulsion method. The 1990s saw the launch of the confit range, and other dressings later expanded the offering.
Today, Michèle Didden, the founder’s great-granddaughter, leads the company. She represents the fourth generation. Her children, Pierre and Laurence, have joined the business: the fifth generation is already at work. One focuses on figures, planning and digitalization, while the other works on business development and marketing. On site, between 35 and 45 employees work depending on the season, many of whom have been there for more than a decade. This loyalty gives the workshops a particular atmosphere.
Staying here
A few years ago, another scenario was possible. A building had been acquired in Nivelles, but the project was ultimately abandoned. Leaving Brussels would have meant moving away from long-established teams and breaking with a nearly century-old anchor. The choice was clear: stay.
At a time when many companies are questioning their location, this family business shows that it is possible to produce and grow while remaining faithful to one’s territory. The site in Molenbeek-Saint-Jean now offers the space needed to develop the activity. Part of the turnover (15%) comes from exports, mainly to the Benelux, but the centre of gravity remains firmly in Brussels.
In 2025, Didden celebrated its hundredth anniversary. As we leave, the scent of spices lingers a little longer. Like a subtle reminder, between vats and pallets ready to ship: Brussels is in the walls, in the teams and in the recipes.
