A style of Belgian beer with a distinctive sour cherry flavour, traditionally made by slowly fermenting lambic beer with morello cherries.
Originally specific to the Brussels area and using the variety of cherry growing in the Schaarbeek area north-east of the city, krieks are now also commercially brewed elsewhere.
1930s; earliest use found in Notes and Queries. From Dutch kriek black cherry, beer with cherry flavour, probably from classical Latin graecum, neuter singular of graecus, probably after post-classical Latin prunum graecum, lit. ‘Greek plum’ (although this is first attested later: 1517 in a Latin–Dutch glossary).
