Green olives are picked before the olive ripening cycle has begun, they are either green or yellow.
Olives come from Olea Europea, a small tree. Olives are the fruit of the olive tree. 90 percent of harvested olives are turned into olive oil, while the rest are sold as table olives. Table olives are classified into 3 groups: green olives, turning color olives (semi-ripe) and ripe olives.
