3 Fonteinen “Intens Rood” (Intense Red) is the result of macerating hand-picked whole sour cherries on lambic for at least six months, in a proportion of one kilogram of fruit per litre of lambic, and is then blended again with more lambic to obtain a minimum intensity of 450 grams of fruit per liter. The kriek lambic ferments in the bottle for at least another six months and develops into an intense wine-like fruit lambic. This bottle fermented, unfiltered and unpasteurised lambic is all-natural with no artificial juices, syrups, or sugars added.
