As the mother of 5 children, Louise managed to run the brewery successfully. When Emile was almost 80 years old, Louise entrusted the brewery to one of their sons, Paul. Together with his brother Ernest, the two managed to keep the brewery going even after the destruction wrought by the First World War.

However, Luc soon realised that his small and humble brewery was far from ready to compete with the large pils breweries. He knew that he needed something special in order to make his brewery stand out from the crowd. As a result, he decided to focus on the production of an aged brown beer - similar to the one produced back in 1930. Luc named it Bacchus, completely stopped brewing pils, and changed the name of the brewery to Van Honsebrouck as a tribute to his great-grandfather.

In 1957, Luc was greatly inspired by Bacchus’s huge success and as a result, created a second specialty beer - gueuze. However, this beer style was only brewed in the Zenne valley, so Luc had to figure out how he was going to transport the wild yeasts needed for spontaneous fermentation from Zenne valley all the way to Ingelmuster.

The beers were a hit, and later on in 1992, beer aficionado Jef Van den Steen claimed that St-Louis Gueuze would be even better if it also came in an unfiltered, bottle-fermented version. Luc took on the challenge and released the St-Louis Gueuze Fond Tradition in 1997 which was Michael Jackson-approved!

To celebrate, the town held its first Brigand parade in 1986, and this parade became a tradition that lasted for years. In that same year, the Van Honsebrouck Family bought the Ingelmunster Castle, which inspired Luc to brew a dark specialty beer - Kasteel Donker - in 1989. Kasteel Donker was the very first beer in the Kasteel range, and was introduced to the public in 1991 and was an instant hit. This marked the birth of the Kasteelbier brand and a few years later, Kasteel Blond and Kasteel Tripel were added to the range.
