Philip Freese is a co-founder and co-owner of Vilafonté, a South African winery that produces varietal red wine. Freese was born in 1945 in Indiana. He was educated at Purdue University (BS) and University of California Davis (PhD) where he studied biochemistry. He left the field of biochemistry to pursue a career in the wine industry in 1978, first working as vineyard manager for a CalPlans vineyard in Napa County and then, beginning in 1982, as a winegrower for Robert Mondavi, eventually becoming Vice President of Winegrowing. In the 1990s he started both a wine consulting firm, Winegrow, and, with his wife winemaker Zelma Long, the winery Vilafonté in South Africa.
