(Forbes) - On Spring Mountain in Napa County, it's easy to get distracted by the beauty of the place. But in the vines at Cain Vineyard & Winery, there is work to be done, and this work is performed by the same hands, year-after-year, season after season. When vineyard specialist Enrique Cortés handed me his tools in a February pruning lesson, I was one of the few other people, besides Cortés and his close-knit team, to handle his vines in years.

This is rare in the wine grape industry, and in the agricultural industry as a whole. Many wineries bring in vineyard management firms or seasonal labor to do work in the vines. This isn't necessarily a bad thing -- at times it is a choice and other times it is a necessity -- but there are wineries that make a permanent team a priority.
