Not much has changed in the cultivation of olives in the past few thousand years. Olive trees are hardy and can withstand craggy conditions, little water, and lots of wind and sun. They’re fairly low maintenance, usually needing pruning once a year at harvest time. As with any agricultural crop, weather and soil conditions play a big role in the outcome. But it’s during the harvest and pressing that a small producer can really control the oil’s quality and style.
