The extra virgin olive oil is produced in our factory on the same day by the unique method of “first cold extraction” from selected crops which come from the Messinia and Ilia and are picked by local farmers. This method of production is considered unique because it does not ‘Burn’ the olive oil processing and retains all the ingredients of the rare Olive oil juice.
With respect to the product, people and the environment we have been applying the most modern standards in out renewed and renovated factory.Characteristics of olive oil are: Low acidity up to 0.4 – Golden color and strong flavor, variety Koroneiki

We are a traditional Greek family whose occupation is growing olives and producing olive oil extra virgin. It was around 1900 when our grandparents started this business, initially owning 20 acres of fertile Messinian Land, a property which was increased to 160 acres, containing 3500 olives trees of variety “Koroneiki” by our parents Konstantinos and Diamando Giannopoulos, who continued in the footsteps of their parents with the same love and care for olives.
As well as growing olives, Konstantinos and Diamando took a big step, and for the past 55 years they have been operating one of the biggest olive oil factories in the Peloponnese region, which they constructed themselves. The soul of this family business is our mother Diamando, a unique woman, who is also the only female in the olive oil business in the region, and is also responsible for both owning and running the factory. So, In her honour, we decided to name our olive – oil after her, which is henceforth called “Diamond Messinian Extra virgin Olive oil”.

    My husband and I are going to visit the Peloponese area in July and we would like to visit an olive oil factory to see the beautiful olive grooves and to see how olive oil is made. We know that July is not the season for olive oil, although we were wondering if your factory was open to visitors to allow us to see the installation.

    Please let us know if it would possible for us to visit your factory.

    Thank you,
