(Wines&Vines) - The University of California Cooperative Extension recently published a report about this year’s sample costs to establish a vineyard and to produce Cabernet Sauvignon grapes in Napa Valley. It’s very comprehensive stuff that most growers would find fascinating, even if their varieties, growing conditions and costs—notably land costs—are different. The report was prepared by Monica L. Cooper, UC Cooperative Extension farm advisor for Napa County; Karen M. Klonsky, UC Cooperative Extension specialist, Department of Agricultural and Resource Economics, UC Davis; and Richard L. De Moura, staff research associate for the Department of Agricultural and Resource Economics, UC Davis, with the assistance of the Napa Valley Grapegrowers and its members.
