Arauco Olives are dark green olives grown in Spain and in Argentina.
They are very large olives harvested green, cured in brine, and usually flavoured with herbs such as rosemary.
The trees were brought to Latin America by the Spanish at the time of the conquest. They are now the main olives grown in Argentina.
Black olives are also made from the olives.
