In origin, this sweet-acid drink was obtained by adding fresh black cherries to a barrel Lambic of 6 months young. The addition of fruits provokes a new fermentation in the oak barrels. After another 8 to 12 months, only peels and stones left and the Kriek-Lambic is ready to be filtered and bottled. The residual sugar can be adjusted with straight-on fruit juice to give a refermentation in the bottle. This traditional type of fruit beer is more acid and less fruity. Because of the limited availability of the Schaerbeekse Cherries, and to brew a less sour and more fruity Lambic beer, Lindemans farm brewery developed an unique natural method using pure cherry juice from unfrozen cherries. This straight cherry juice is blended with selected Lambic of different ages. Kriek has a pink-red colour and the delicious taste of sparkling cherry champagne.
