Overview

Oregon grows 99 percent of the U.S. hazelnut crop. In 2010, a biennial off-year, the state's production dropped to 27,000 tons of hazelnuts, 43 percent less than the previous year. The value of the crop was $59.7 million, decreasing 25 percent from 2009.   (NASS 2011) 

Turkey still dominates the hazelnut industry, generally supplying 80 percent of the world's total (FAS 2010). The European Union ranks second, producing about 13 percent, and the United States third, producing about 7 percent (Hazelnut Council).   April 2011 ... Hazelnuts
