1939
Year that world-renowned U.C. Davis viticultural professor, the late Dr. Harold Olmo, planted a research station of cabernet sauvignon clones at Larkmead Vineyards in the Napa Valley. Some of Napa’s most famous cabernets have these clones to thank for their success. Olmo’s research spanned the world, earning him a reputation as the “Indiana Jones” of viticulture.
