3 Fonteinen Oude Geuze Vintage is a blend of one-, two-, and three-year old lambics. Instead of releasing them after minimum 6 months of bottle conditioning, the vintage series have been cellared for at least three years up to even five years and longer before being released. For an Oude Geuze to become a Vintage, it features characteristics that are unique, sometimes surprising or outspoken. Spontaneous fermentation, patient maturation in oak barrels, and continued evolution of the ecosystem in the bottle result in a distinctively complex and elegant natural beer.
