The stoning: In June, the
fertilized flowers start what we call the stoning
(the time when the fruit stone start to harden)
and the fruit pulp called « drupe »
becomes fleshy.
Ripening: The olive fruit
already acid green, it starts to ripen:
the
color of the olive fruit starts to change from delicate
green to darker green then to violet in autumn and
lastingly to black in winter.
