In 1615, Willem Neerfeldt founded a brewery in the village of
Grolle, which has now become Groenlo, in the Dutch province of
Gelderland. His daughter married Peter Cuijper, who was appointed
Guild Master of the brewers' guild in Grolle in 1676.
In 1895, this successful brewery, known as 'De Klok', was sold by
their descendants to Theo de Groen, offspring of another true
family of brewers. Meanwhile, in that same year, a number of
textile manufacturers, merchants and bankers decided to set up
another beer brewery, 'De Enschedesche Bierbrouwerij'.
During the First World War ingredients were in short supply,
causing the quality of the beer to drop, accompanied by a sharp
fall in sales. The management of De Enschedesche Bierbrouwerij
therefore decided to sell the business to Theo de Groen.
In 1922, De Klok in Groenlo merged with De Enschedesche
Bierbrouwerij to become 'De Klok', later renamed 'De Grolsche
Bierbrouwerij'.
In 2004, Grolsch's new state-of-the-art brewing facility, located
on the border between Enschede and Boekelo, became operational,
replacing the old breweries in Enschede and Groenlo.
