If you enjoy a glass of wine while reading a good mystery you’ll appreciate this story. Zinfandel has been in the U.S. since the early 1800s yet no one knew for sure where it originated. Is it related to Primitivo? Finally in 2001, with help from others around the globe, U.C. Davis professor Carole Meredith solved the mystery and in turn helped save the heritage grape from extinction. Carole shares her exhaustive research and discovery with me in this in-depth interview. You’ll also hear about her own vineyard, Lagier Meredith, which sits high atop Mt. Veeder overlooking Napa Valley.
