Zelma Long, born in Oregon in 1945, is an American enologist and vintner. She attended the UC Davis School of Enology and Viticulture and worked for Long Vineyards and Robert Mondavi Winery, which she served as chief enologist during the winery’s 1970s heyday. In 1979 she was hired to be chief winemaker at Simi Winery in Sonoma County, eventually becoming president and CEO of the winery. While planning for her retirement from Simi in 1996, she and her husband, viticulturalist Phil Freese, started Vilafonté winery in post-apartheid South Africa. In a separate interview released in 1992, Long discusses her years at Mondavi and Simi; in this interview, Long reflects on the history of winemaking in California and the role of women in the industry; the focus of this oral history, however, is the building of Vilafonté, her work as a consultant to many wineries around the globe and her role as a leader in the global wine industry.
