More California winemakers using less water to grow grapes

The grape vines that grower Frank Leeds tends in Napa Valley stand among the unheralded heroes of California’s drought, producing decade after decade of respected Cabernets and other wines without a drop of added water. In a state where farms and dairies take the biggest gulp of the water supply, Leeds and the owners of his Frog’s Leap Winery are among a minority — but a growing minority — of California growers and winemakers who believe that when it comes to wine grapes, the less irrigation, the better.
