(LodiNews) - Grape growers in the Lodi Appellation are having a booming year, but experts say it’s too soon to reveal the great prices Lodi winegrapes are earning. The harvest statewide is estimated at 3.7 million tons, up from 3.3 million tons in 2011, the Wine Institute, a wine advocacy group, reported in early November. Data is not yet available on the average prices winegrapes are earning, or precisely how much fruit came off the vines this season. That information will come out in February’s Crush Report.
