Brewing beer used to be completely different from how it is today. Back then, there were no stainless steel tanks and no computers. Everything was done manually and the master brewer’s tacit skills were crucial for the quality of the beer.
Located behind the brewery's large entrance gate on Wycker Grachtstraat is an underpass, with the former offices to the left. Behind them is the lemonade factory 'Malifa' ('Maastricht Limonade Fabriek'). Adjacent to the large courtyard are several areas where parts of the brewing process took place. These include: the water and boiling kettle; the cast-iron mash tun; the cooling coils; the ammonia compressor; fermentation vessels; and the bottling plant.
