THE
DIFFERENT QUALITIES OF OLIVE OIL
Olive Oil
is a precious and delicate natural product obtained thanks to human’s hard and
skilled work. Different categories are distinguished according to its color,
taste, smell and flavor.
Acidity,
also, is an important factor in the oil quality. It must be not higher than 1%
in the extra-virgin and than 2% in virgin olive oil.
Olive oil
is classified into four categories: virgin, refined, olive and olive-pomace.
Virgin olive oil is classified into further subgroups according to organoleptic
tests and acidity level: extravirgin, virgin, ordinary and lampante. Refined olive oil is obtained from virgin olive
oil by refining methods that do not modify the original glyceridic
structure.
Olive oil
is produced by blending refined and olive oil. Olive-Pomace oil is obtained by
treating olive pomace with solvents, and is sub-classified into crude, refined
and olive-pomace oil.
In Sicilian
extra-virgin oils, characteristics and flavors of the area of origin are
entwined with those typical of the whole Island. Cultivars are strongly
affected by environmental factors and features of the plantations.
Numerous
Sicilian oils have the Protected Designation of Origin, that is granted to products
whose manufacturing process is related to a defined geographic area according
to European Union’s standards. Among DOP (Italian for PDO) Sicilian oils are:
the oil from Hyblean Mountains, from provinces of Siracusa, Ragusa and Catania,
that is a medium fruity fragrant and slightly spicy oil; the oil from the
Demone Valley, in the Messina area, that is a medium fruity and sweet oil; the
oil from Trapani’s valleys, a full-bodied oil with a spicy-fruity
flavor; the oil from
Etna Volcano, that appears to have intermediate characteristics between Messina
and Hyblean oils; the oil from the Belice Valley, characterized by intense
fruity aromas; the oil from the Mazara Valley, with a delicate fruity flavor
and an intense grassy aroma.
