3 Fonteinen Framboos Bio3 Fonteinen's first fully organic Framboos! They macerated two different raspberry varieties from West Flanders on young lambik for a good four months. Then blended with some more one and two year old lambik. All in all, they used lambikken originating from four different barrels and eleven different brews, all made with grains coming from their Cereal Collective and from Pajottenland.
