Abstract:
... This article gives an overview of the current use of the European system of protected designation of origin (PDO) and protected geographical indication (PGI) for Spanish table olives. To date, there have been two PDOs recognized by the European Commission, the PDO “Aceituna Aloreña de Málaga” (2012) and the PDO “Aceituna de Mallorca/Mallorquina” (2014). In both cases, olives are debittered in brin ...
