Gueuzerie Tilquin, located in Rebecq, is the only gueuze blendery in Wallonia - a prestigious fermentation hub dedicated to spontaneous fermentation and the century-old lambic beer tradition. Founded in 2009 by bioengineer Pierre Tilquin, the blendery sources finished lambic from renowned breweries and ages it in oak barrels for one, two, or three years before blending it into Oude Gueuze Tilquin à l’ancienne - bottle-refermented for at least six months.
