The olive harvest can last from November to March. Olives are usually collected in nets, strewn on the ground to catch what's fallen from the trees at their most perfectly ripe, and then processed within 24 hours. For lower grades of olive oil, the trees are shaken to encourage more olives to fall, or the fruit is actually hand- or mechanically picked. Historically, olives were crushed by hand in large stone basins. Today, producers use mechanical, stainless-steel grindstones to crush olives and then a centrifuge to separate the oil from the paste, producing the first or cold pressing, to which no heat or chemicals have been added. In this form, the oil is at its optimal in color, flavor and nutritional value. It then undergoes a gentle filtering to remove sediment and becomes extra virgin olive oil. Like wine, the flavor of olive oil is heavily dependent on soil, climate, variety, age and processing. Unsurprisingly, its flavor characteristics - delicate, mild, spicy, nutty, floral, fruity - resemble the terms one hears used when discussing wine.
