At this time owned by a certain Mr Gérard, it was home of the Société des Droits et Devoirs de l'Ouvrier from 1848 to 1849.

Expropriated due to the work at the junction,[9] in 1927 the café moved to Rue Montagne aux Herbes Potagères, officially taking the name "À la Mort Subite" in 1928.

Théophile Vossen then gave the name "Mort Subite" to the beer (gueuze, faro, kriek) he was producing.

The beer is exported to many countries thanks to the fact that the De Keersmaeker brewery was taken over by an important malting group, Alken-Maes.

The date, 1684, displayed on the bottles refers to the founding of the De Keersmaeker brewery, with its first brewer Joris Van Der Hasselt, even though the farmhouse of that name had existed since 1604.
