Chemical
methods (solvents) are used to dissolve oil from the residue. Olive
stones are woody and the oil which remains cannot be removed naturally,
so it is removed through distillation with the use of solvents. Acidity
does not exceed 1.5%.
Extra Virgin Olive Oil up to 90%
Greek
olive oil producers offer extra virgin olive oil at a percentage of
80-85%. In some areas, such as Crete, this figure is greater, as much
as 85-90% and tends to increase!
