A true Geuze. A blend of 1, 2, and 3 year-old lambic unfiltered and unpasteurized and aged in the bottle for at least 6 months after blending. Continued fermentation in the bottle give this Geuze its famous champagne-like spritziness. The lambic that goes into it is brewed only with 60% barley malt, 40% unmalted wheat, aged hops, and water, spontaneously fermented by wild yeasts, and matured in oak casks.
3 Fonteinen Oude Geuze is a blend of one-, two-, and three-year old lambics. 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. No two bottlings are alike, as there are multiple variables in the blending process, a variety of barrel sizes and shapes, differences in aged lambic proportions in the blend, etc.
