Olive oil production at Companhia das Lezírias dates back to the 18th century. XIX Currently, with an area of 70 hectares of olive groves planted in Herdade de Catapereiro, 5 different varieties and in sandy soils, Companhia das Lezírias focuses on the production of high quality extra virgin olive oil reflecting the values of CL in each bottle produced.
Since 2015, with the incorporation of Alter Real into Companhia das Lezírias, the olive grove area has increased by about 30 ha. It is a traditional secular olive grove, monovarietal "Galega" planted in poorly structured soils of granite origin in Tapada do Arneiro, district of Portalegre. It is in this olive grove that the mares and foals of the Alter Real Stud Farm graze daily. The olive oil we produce from these olives is packaged in small gourmet bottles in a numbered and prestigious series.
