Resumen: Olive tree crops and the olive oil market are becoming less and less diverse due to the rise of intensive growth varieties, with the consequent loss of varietal richness provided by oils from minority and autochthonous cultivars. “Royal de Calatayud” and “Negral de Sabiñán” are two local minority cultivars in Aragon (Spain). Fruit parameters such as ripening, fresh weight, and oil yield were evaluated, as well as physico-chemical and chemical composition parameters in olive oil in comparison with “Arbequina”, a cultivar widespread in Spain and other countries. Fruits were harvested from October to December in 2017 and 2019. Chemometric analysis revealed significant varietal differences among the three cultivars. In comparison with “Arbequina”, higher oil yields were obtained in the two local cultivars. “Royal de Calatayud” has a higher oleic acid content and a greater quantity of phenolic compounds. It thus displays a better nutritional profile than “Arbequina”. This preliminary study shows that “Royal de Calatayud” could be regarded as an excellent alternative to the “Arbequina” cultivar in the parameters analyzed.
