Portugal

Ginjinha or simply Ginja, is a liqueur made by infusing ginja berries, (sour cherry) (Prunus cerasus austera, the Morello cherry) in alcohol (aguardente is used) and adding sugar together with other ingredients. Ginjinha is served in a shot form with a piece of the fruit in the bottom of the cup. It is a favourite liqueur of many Portuguese and a typical drink in Lisbon, Alcobaça and Óbidos. Other regions produce ginja with protected designation of origin, for example the Ginja Serra da Estrela.
