VIRGIN OLIVE OILS
Obtained by pressing the olives alone.
Oils obtained from the fruit of the olive tree solely by mechanical or other physical processes, under conditions which do not cause alterations of the oil, and which have not undergone any treatment other than washing, decantation, centrifugation and filtration, excluding oils obtained by solvent or with adjuvants with a chemical or biochemical action or with re-esterification processes and any mixture with oils of other nature. These olive oils are subject to the following classification and names:

Virgin olive oil whose organoleptic score is equal to or greater than 5.5, whose free acidity expressed as oleic acid is a maximum of 2g per 100g and having the other characteristics compliant with those envisaged for this category. Lampante virgin olive oil, whose free acidity, expressed in oleic acid, is greater than 2g per 100g and having other characteristics compliant with those envisaged for this category.
REFINED OLIVE OIL
Olive oil obtained from the refining of virgin olive oil with a free acidity content, expressed as oleic acid, not exceeding 0.3g per 100g and having other characteristics compliant with those envisaged for this category.
