Grape Spotlight: Croatian Tribidrag (Crljenak Kaštelanski, Pribidrag, Kratošija ) aka Zinfandel - The idea that California Zinfandel was equivalent to Italian Primitivo was also proposed by UC Davis professor Austin Goheen and Wade Wolfe in the 1960s. Goheen visually inspected Primitivo from Puglia (Southern Italy) and considered them identical whereas Wolfe used isozyme analysis to strengthen that hypothesis. But it wasn't until 1995, after three years of DNA analysis, when Dr. Carole Meredith, Professor at UC Davis, concluded that Zinfandel and Primitivo were, in fact, the same grape variety. http://winecompass.blogspot.com/2020/04/grape-spotlight-croatian-tribidrag.html
