The cultivation

As all ancient olive groves, most of our trees are wild trees, and grafted so as to improve their resistance to drought and disease.

In order to produce a superior quality oil, an olive tree must be healthy and requires the following conditions: a dedicated producer, lots of sun, some rain, fertile and well-drained soil, a mountainous terrain, and plenty of TLC. The producer must wait for the perfect ripening of the fruit before harvesting as well as ensure that no chemicals are present at any stage of the growth process.
