The oil quality is determined by its origin. Specifically, the extra virgin olive oil of Bonum Terrae that comes from North Mylopotamos in Rethymno, Crete, is declared as Protected Designation of Origin (PDO). The soil, the climate and the way of growing and the variety of olives, are the factors that contribute to its evaluation. The many hours of sunshine and the acidic pH of the soil (which is a distinctive feature of the region) are responsible for the highly attractive yellow-golden color and the sweet fruity flavor of the oil.

The quality characteristics of the extra virgin olive oil PDO "NORTH MYLOPOTAMOS RETHYMNO CRETE" are of the highest level in relation to the standards of the International Olive Oil Council. This is due to the way of harvesting and processing of the olive wrist.

Furthermore, the processing of the olives' wrist takes place in modern centrifugal factories. The temperature during the kneading of the olive paste and any other processing step cannot exceed 27 degrees, in order to keep the valuable nutritional properties of the final product.
