In 1997, Zinfandel Advocates and Producers partnered with the UC Davis department of enology to initiate the Zinfandel Heritage Vineyard Project. This project had four key goals: 1) Preservation of historical Zinfandel vines, 2) Identification of different clonal selections of Zinfandel, 3) Propagation of a variety of “clean” Zinfandel selections and 4) Experimentation of how the different selections grew in different regions.
