(Wines&Vines) - The California wine market is experiencing a structural shortage and likely won’t return to balance for at least four years, according to Matt Turrentine, who spoke Thursday during the Central Coast Insights Conference. The partner with Turrentine Wine Brokerage said, “We’ve undisputedly entered a period of shortage for all areas and varieties.” Turrentine said that in 2011 California shipped out 257 million cases of wine, while the 2011 harvest only yielded the equivalent of 210 million cases—a disparity of 47 million cases, or 750,000 tons.
