Every
year in November and December, Tuscany is engaged in the collection
of the olives. Still today the cultivation
is tied to traditional systems and mature olives are picked
by hand. In order to avoid the olives go lost, pickers place large
nets underneath the trees.
Olives
usually are positioned in several layers on mats and immediately
taken to a mill for the grinding because fermentation could start
and alter the flavour of the oil. In the mill the leaves are removed
and the olives are weighed and washed before to grind them into a
paste. Stone rollers were the traditional grinder.
The
paste is spread on stacked mats and pressed. The liquid obtained
is passed through one centrifuge to separate the oil from the
water. Extra virgin olive oli,
the best one, comes from the first pressing. Further pressings produce
lower quality oils.
Freshly
extracted oil is poured into stainless
steel containers and immediately bottled.
After the oil is pressed out of the paste, the pomace or sansa is
destined to successive pressing, refining and uses. Today the traditional
grinders and presses are often replaced by metal machinery
