Olives put in opened boxs are brought from the countryside to a place called “frantoio”(in English Oil Mill)

Olives are washed

After the washing, olives are pressed

Did you know that the ancient Greeks used to press olives 5000 years ago?

The method used by Greeks is still used today.

They used the olive press, which is a very heavy stone, that was usually pulled by a donkey.

The olive paste

It generally stays under the stones for 30 to 40 minutes. This has three objectives:

to guarantee that the olives are well ground to allow enough time for the olive drops to

join to form the largest droplets of oil to allow the fruit enzymes to produce some of

the oil aromas and taste

When the paste is ready…

It is put on fiber disks, which are stacked on the top of each other

These disks are put on a hydraulic piston, forming a pile. Pressure is applied on the disks, thus compacting the solid phase of the olive paste and percolating the liquid phases

Finally, the liquid is purified

The process is called “Decantation” and it separates liquid from all the small solid substances througout a faster vertical centrifuge

Oil is ready to be used e put in bottles
