California's olive-growing region is primarily located in the Central Valley, where the climate is ideal for olive cultivation. The warm, dry summers and mild, wet winters create perfect conditions for the olive tree, allowing for high-quality fruit production. The state is known for its diverse varieties of olives, including Manzanilla, Kalamata, and Mission. California produces a significant portion of the United States' olive oil, contributing to both local and international markets. The region's agricultural practices focus on sustainable farming methods to ensure the health of the land and the quality of the olives.
