[3] At the same time, Adrien Piedbœuf began producing motor vehicles in his workshops in 1900, founding the Impéria brand in 1904.

In 1853, his son Jean-Théodore Piedbœuf, who succeeded him at the head of the boiler works, began brewing.

[2] Until the First World War, production remained modest, covering only the surrounding area.

In 1965, on the eve of the launch of Jupiler (in September 1966), the company passed the million hectoliter mark and employed 1,800 people.

By 1979, after several acquisitions, the group employed 3,800 people and produced 2.75 million hectoliters of beer, as well as other lemonades and fruit juices.
