Installed in Bierghes in the Senne valley, the Gueuzerie Tilquin is the only gueuze blendery in Wallonia. A gueuzerie, or Geuzestekerij in Dutch, is an enterprise where Gueuze à l’ancienne (or Oude Geuze) is blended.
Freshly brewed worts are purchased from different producers in the region (Payottenland and Brussels), and pumped in oak barrels for fermentation and ripening, during 1, 2 or 3 years. The lambics obtained are blended and bottled to give, after 6 months of refermentation, the Gueuze Tilquin à l’ancienne, which has 7.0% alc / vol and is available in 37,5cl and 75cl bottles.
