16. 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

17. 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

19. 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
