Oude Gueuze Tilquin à l’Ancienne (6.0% alc/vol) is a spontaneous fermentation beer, produced from the blending of 1, 2 and 3 years old lambics. It is unfiltered and unpasteurized, and refermented in the bottle for at least 6 months. The lambics used were fermented and oak aged in our installations. These lambics are coming from worts brewed by Boon, Lindemans, Girardin and Cantillon breweries.
