The Douro Valley's arid, Mediterranean climate, very low yearly rainfall (18 in) and mineral-heavy, schist soils makes for olive oil with concentrated flavors. We harvest the trees at the end of November, at which point the olives are very ripe (vs in Italy they usually harvest in October, which gives Italian olive oil that green spiciness). All it takes is hitting the trees with large sticks to have it raining olives! The olive oil is pressed using a cold method of extraction.
