Oude Geuze Boon is one of the finest examples of the traditional 100% spontaneous fermentation Lambic style.

This Lambic beer is aged for 1, 2 or 3 years in oak casks. The blend, a mild average 18 month old Lambic (unsweetened, unfiltered, unpasteurized) is refermented in the bottle and can be stored for up to 20 years.
