The Calogiuri family, respectful of traditions, see that the olives are
gathered by hand when they are not quite ripe, in the month of November. In the firm's
olive press the olives are cold crushed with care and the oil is extracted by means of the
"surfacing" method. This is an old technique which consists in waiting, after
the crushing, for the oil to come to the surface from the liquid present in the olives,
which has been poured into particular containers, that is, for the oil to come to the
surface detaching itself naturally from the water because of the different specific weight
(oil, as is well-known, is lighter than water). This "floating" oil is skilfully
collected in special jugs by hand. This is clearly an old method used in the past when, as
there was no electricity, the simplest phisical laws were resorted to, without the help of
mechanical means. The product obtained, "Pura lacrima di affioramento"
("Pure surface drops"), apart from being easier to keep because it is not very
humid, is particularly fresh and delicate, as it is made up of the lightest part that has
come to the surface. It is, in few words, the best quality of extra pure oil. The
"affiorato" oil (that is the oil on the surface) is then placed in steel tanks
where, after a month of natural decantation at a costant temperature of 14° C , it is
ready to be bottled.
