Godfather of California olive oil Paul Vossen to retire in June
“California producers are now capturing the fresh fruit flavor of the olive,” Vossen said. “When I started, they were getting bad information from old-world producers. After visiting newer olive oil production regions and tasting good olive oil, I thought, ‘Oh boy, this is what we need in California.'”
Vossen launched a tasting panel and put on educational seminars. He studied and researched olive oil production, planted demonstration orchards and traveled around the world to learn from the most experienced producers and researchers.
California growers now use up-to-date farming methods, harvest mechanically or by hand to ensure fruit quality, and replaced antiquated oil extraction techniques with stainless steel decanters and centrifuges. The outcome is olive oil that tastes spicy, peppery and pungent; oil that serves more as a flavorful and valued condiment than an ordinary fat.
Vossen was immersed in extension education his whole life. His father was an extension agent in Minnesota for 40 years. His sister was an extension home economist. Though he went to the University of Minnesota with no intention to follow in their footsteps, he took a botany class and “totally fell in love with plants,” Vossen said. He earned a bachelor's degree in horticulture in 1978.
After graduation Vossen traveled to Happy Camp, near the Oregon border, to visit his brother.
“It was 70 degrees and sunny in the winter. I thought Northern California was paradise,” he said, and he decided to stay.
Vossen enrolled at UC Davis, earning a master's degree in pomology in 1981. Just a few days later he started his life's work as the pomology advisor for UC Cooperative Extension in Sonoma County. He later added responsibility for specialty crops in Marin County.
Over his career, Vossen developed and implemented a comprehensive research and extension program. He wrote hundreds of articles and made many presentations on the production and marketing of apples, Asian pears, kiwis, hazelnuts, chestnuts, berries, heirloom tomatoes and other crops.
He authored some of the first UC Agriculture and Natural Resources publications on organic production, founded the Sebastopol Apple Promotion Committee and a Sonoma County ag marketing program to promote local products, and formed the California Olive Oil Council. His olive oil sensory panel was the first to be recognized by the International Olive Oil Council in the new world.
A significant achievement of Vossen's career was establishment of a UC Master Gardener program in Sonoma County in 1982. At the time, few California counties had Master Gardener programs in place. Vossen enlisted volunteer gardening enthusiasts to be trained by UC academics in research-based gardening systems. The program has continued for 34 years, training 30 new volunteers every year. There are currently 320 active UC Master Gardeners in Sonoma County.
“We were the first to put together a board of directors and develop original programming,” Vossen said. “We made a difference in the community, reducing landfill inputs of green waste, improving water conservation and reducing pesticide use.”
In retirement, Vossen said he plans to garden, travel and enjoy good food.
“I will judge at olive oil competitions, do some private consulting and enjoy continuous summers hiking all over the northern hemisphere May to October and the southern hemisphere November to April,” Vossen said.
