Wine makers are returning to traditional wine storage techniques in order to cut utility and construction costs. Rutherford Hills Winery, one of California’s Napa Valley vintners, has opted to dig a wine cave rather than proceed with plans for building a 30,000-square-foot refrigerated warehouse. Using electricity only for lighting, the cave will maintain ideal storage conditions — a natural temperature of 60° to 65°F, with 70% humidity — regardless of outside conditions and should save a minimum of $12,000 a year in air-conditioning costs.
