16 Rocky, Oroville, CA 95965

This impressive 399-acre olive orchard, located near Oroville in Butte County, presents a prime investment opportunity. Originally established in 1913 by UC Berkeley professors as part of the Berkeley Olive Association, it was once the largest planting of Mission olives globally and a key part of California's olive-oil heritage. Recognized for its historic value, the estate is eligible for both state and national historic registries as the Berkeley Olive Association District. The property is entirely dry farmed, relying on unique subsurface moisture 68 feet below ground, which enables remarkable resilience even in drought years. Planted at a spacious 65 trees per acre on 30-foot triangles, the low-density layout ensures optimal soil nutrients and tree health. The trees have thrived for over a century under organic practices, enhancing both longevity and terroir. All olives are hand-picked and hand-pruned; organic, regenerative methods are central, with chipped prunings returned to the soil. The olive oil produced here has attained global recognition, with biophenol levels ranked in the top 2.5% worldwide from 2010 to 2015. Harvested in stages to produce distinct profiles—the Classic, mid-harvest Gold, and buttery Reserve—the oils have earned numerous gold medals and best-in-show accolades at competitions such as Los Angeles and New York International contests. Historic stone houses from the 1930s grace the orchard. Future plans originally included transforming a barn into an olive mill.
