Jaén Olive Oil Pressing

Molturación y Prensado de Aceite de Oliva de Jaén

The pressing of extra virgin olive oil in the traditional stone mill and hydraulic press almazara of Jaén — the province that produces more olive oil than any country outside Spain. The craft involves the entire quality chain from olive harvest maturity assessment through milling, malaxation, and pressing, with the almazarero reading the oil quality at the separator by nose and taste. Jaén's Sierra Mágina DOP produces oils of exceptional quality from Picual olives, and the master oil taster (catador de aceite) is the most technically trained sensory professional in the Spain food craft archive.
