Kriek refers to a lambic beer that is flavored with cherries; the beer which has a characteristic fruit flavor, but without sweetness. Moreover, Kriek is a famous type of Belgian beer fermented with sour Morello cherries. The fruit used in the production process has traditionally been the rare Schaarbeekse Krieken grown in the Brussels area. However, in recent years it has become rather difficult to obtain in sufficient quantities, so some brewers have substituted it with other types of sour cherry, often imported from abroad. Kriek is made from lambic beer, to which sour cherries with pits are added, facilitating the further refermentation of the remaining sugar.
