The brewery site dates further back to 1680 as a farm brewery and distillery owned by the Claes family. The brewery was also believed to have adapted the champenois method for lambic from Dom Pérignon, a French champagne producer. Delplancq suggests the origins of the name [[The_Language_of_Lambic#Gueuze.2C_Geuze|"Gueuze"]] were tied to Louis Paul from Brasserie Hygiëna in [[The_Language_of_Lambic#The_Town_of_Lembeek|Lembeek]], who in 1870 had the nickname "Geus" for his liberal politics (he was also the town mayor). <ref name="Guinard">Jean-Xavier Guinard, [[Books#Classic Beer Styles: Lambic|Classic Beer Styles: Lambic]], 1990.</ref> The people of [[The_Language_of_Lambic#The_Town_of_Lembeek|Lembeek]] therefore called this beer "lambiek van bij de Geus" or "lambic of the Geus brewery". <ref name="Delplancq">[https://www.lambic.info/Les_Brasseurs_du_Lambic:_Données_Historiques_et_Géographiques. Delplancq, Thierry. Les Brasseurs du Lambic: Données Historiques et Géographiques. P. 262-263.]</ref> In 1870, an engineer named Cayaerts was hired. Together they began experimenting with method Champenoise, and eventually bottling Gueuze Lambic by 1875. <ref name="Guinard">Jean-Xavier Guinard, [[Books#Classic Beer Styles: Lambic|Classic Beer Styles: Lambic]], 1990.</ref> With no heirs, Louis Paul sold the brewery to Pierre Troch in 1898. In addition to brewing lambic, until WWI Troch supplied wort to [[Brasserie_Cantillon|Cantillon]], which was co-founded by his daughter Marie Troch.
The copper kettles in the brewery were seized during WWI, and iron kettles were then installed. It is believed that the brewery was renamed Brasserie Hygiëna at this time to emphasize the purity of the brewery, but there are earlier references to this name. In 1919, brewery ownership was under Réne Troch, and the brewery closed in 1927 after the economic crisis. The brewery and warehouse buildings were sold to [[Brasserie_R._De_Vits|Jozef De Vits,]] a local tavern owner and gueuze-blender. His son [[Brasserie_R._De_Vits|Réne De Vits]] continued the family lambic blendery from 1937 until 1978, then eventually sold the brewery to [[Brouwerij_Boon|Frank Boon,]] who still owns it and uses it to store Mariage Parfait.

The location is believed to be at [https://goo.gl/maps/BPEibmouPqL2 Edingensesteenweg 586] in Lembeek. The date of the structure is consistent with the historical timeline and modern evidence links photos of the original brewery cellar. Frank Boon mentions the 1927 closure of the brewery in a 2010 article.
