Henri Vandervelden, who at the time was working for [[Brasserie de la Couronne | Brouwerij De Kroon]] in Uccle during the cold months, and as a fruit buyer and picker during the warmer months, started construction of his own brewery with the help of local brick fabricators. His experience at Brouwerij De Kroon, that at the time specialized in producing various lambics, gave him the necessary skills to continue on with his own brewery. When Henri’s son Egidius married Catharina Hofmans, the groundwork was laid to expand the Hofmans’ family farm and turn it into an actual brewery. In 1922 Egidius set out to update and upgrade equipment in order to begin producing beers. In the meantime, Egidius’ younger brother Pierre Vandervelden continued his father’s blending and brewing business until shortly after World War II ended.<ref name=GeuzeKriek>Jef Van den Steen, [[Books#Geuze & Kriek: The Secret of Lambic Beer|Geuze & Kriek: The Secret of Lambic Beer]], 2012</ref>
