It brings together some 2,500 small olive growers spread across 35 municipalities, with more than 2,500 hectares of olive groves and an average annual production of more than four million kilos of olives. It works mainly with the empeltre and arbequina varieties, with a minority presence of negral, royal and verdial. Ainzón is home to industry bodies and oil mills that bottle the region's oil.
