“My gueuze conforms to the taste of the times, it’s refreshing and sells well in France, it’s from that perspective that I’ve named it St. Louis.”<ref name=GeuzeFaroEtKriek>Raymond Buren, [[Books#Gueuze.2C_Faro_et_Kriek|Gueuze, Faro, et Kriek]], 1992</ref>
Luc Van Honsebrouck also took issue with the Royal Decree of 1965 which sought to protect lambic against counterfeiting. It stated a geographical boundary of 20km around Brussels was the defined area for lambic production. He learned of this almost by accident, after a visit from lambic brewer Edgar Winderickx, whom he knew from his brewing school days. He appealed against the Royal Decree, and won with the argument that , arguing "If Brussels says people can't make gueze in Ingelmunster, then it simply would not work there". <ref name=GeuzeKriek>Jef Van den Steen, [[Books#Geuze & Kriek: The Secret of Lambic Beer|Geuze & Kriek: The Secret of Lambic Beer]], 2012</ref>
