* In 1965, the Belgian government imposed restrictions on the use of the names Lambic, Geuze, and Kriek requiring spontaneous fermentation and the use of specific raw materials.<ref name=TFP>Teresa de Noronha Vaz, [http://www.amazon.com/Traditional-Production-Sustainable-Development-Geography/dp/0754674622/ref=sr_1_1?s=books&ie=UTF8&qid=1410234809&sr=1-1 Traditional Food Production and Rural Sustainable Development (Ashgate Economic Geography Series)], 1998</ref> This decree was abolished in 1993.
* In 1993, a new royal decree was put in place. This decree specified that spontaneous fermentation must be part of the process and that wheat must be 30% of the grain bill. However, it did not specify how much of the beer needed to be lambic in order to carry the lambic name or specify any regional protections.
* In 1997, five lambic related products were protected by being granted Traditional Specialties Specialty Guaranteed (“TSG”) status. Within Europe, TSG protects the brewing style, however it again does not tie the beer specifically to a region.
* Since 2004, brewers of lambic can also apply for a regional label indicating that it is regional and traditional.<ref name=streekproduct>http://www.streekproduct.be</ref>
