The oil mill is a large bowl that crushes the fruit between the millstones to a pulp. Then you spread the mass on several mats of hemp. This creates a stacked tower. During cold pressing, this tower is squeezed so tightly that oil, as well as water, can escape and be collected. The remaining mass is used for heating.
The last step is to put the liquid in a kind of centrifuge so that the oil and water separate. Once this process is completed, the oil can be bottled by hand in glass bottles or steel drums. Stored at 12 to 18 degrees, the oil retains its original flavor.
