bottle date: 24/12/2022. bottle count: 770 This Zenne y Frontera is a very small bottling of a four-year old lambik that has aged for more than two-and-a-half-years on two Oloroso sherry barrels. The weighted average age of this Zenne y Frontera is therefor more than 45 months; the historical weighted average of geuze blends. The long ageing on the sherry barrels also results in a higher alcohol volume. This is indeed a bottle to be shared on special occasions. Bottle count: 770. 100% 3 Fonteinen.
