Lambic / Gueuze
Lambic beer, which is produced in the Senne Valley and Pajottenland regions of Belgium, is the base beer from which Gueuze and Fruited Lambic beer is then made from. A Gueuze is a type of Lambic beer, made up of a blend of young and old Lambic beer, usually between 1 and 3 years old. Lambic beers (which may later go towards creating a Gueuze) are spontaneously fermented, meaning they do not use commercial yeast or bacteria, instead relying on naturally occurring microbes present in the brewery.
