At Ad-Morum, our Jaén olive oil is not just a product: it is a living heritage, a story that dates back centuries and that we proudly share today.

From Navas de San Juan, in the heart of Jaén, we carefully cultivate our Picual EVOO, blending tradition, innovation, and deep respect for our land.

🌿 The origin of the term "oil": beyond Arabic

It is common to associate the word "oil" with Arabic culture due to its sound. However, its etymology is deeper and more diverse. The word comes from Hispano-Arabic azzáyt, derived from classical Arabic az-zayt, meaning "olive juice". In turn, it has roots in the Aramaic zaytā, which also refers to the olive tree.

This linguistic journey reflects the rich history of olive oil in the Mediterranean basin, where diverse cultures have contributed to its development and refinement.


🏡 Navas de San Juan: birthplace of our oil

Navas de San Juan, our home, is a municipality located in the El Condado region, in the province of Jaén. With an area of 8,505 hectares of olive groves, it is one of the most prominent areas in the production of high-quality olive oil in Spain.

The history of Navas de San Juan is deeply linked to olive cultivation and oil production. Since ancient times, its inhabitants have dedicated their lives to this noble craft, passing down from generation to generation the knowledge and passion for Jaén olive oil.

🛡️ Ad-Morum: a name with history

The name "Ad-Morum" is a tribute to our town and its coat of arms. It comes from the Apollonian vessels, where the inscription "Ad-Morum" was reflected. It is said that these vessels were taken in Roman times from Cadiz to Rome, passing through an area called Ad-Morum, which corresponds to present-day Navas de San Juan, via the Vía Augusta.

This name symbolizes our connection to history and tradition, and represents our commitment to the quality and authenticity of the Picual EVOO we produce.


🌱 Tradition and innovation: the soul of Ad-Morum

At Ad-Morum, we combine ancestral wisdom with the most advanced techniques to offer an excellent Jaén olive oil. Our family business, part of the Acolsa group, is characterized by an innovative mindset and a strong commitment to our productive environment: Andalusia, the European region with the largest agricultural area dedicated to olive trees.

Each campaign, we select the best Picual variety olives, harvested at their optimal point of ripeness, to produce our Picual EVOO. This careful process guarantees an oil with an intense flavor, fruity notes, and a high content of natural antioxidants.
