(CBSNews) - A study released Tuesday shows that Washington state's wine industry has been a bright spot in an otherwise sour economy. The study commissioned by the Washington State Wine Commission, the industry's leading promotional group funded by member growers and wineries, shows Washington wine contributes $8.6 billion annually to the state economy and nearly 30,000 jobs. That's nearly three times the $3 billion concluded by a similar study in 2007. Steve Warner, the commission's executive director, said the results show that Washington state wine is a vibrant and thriving contributor to the regional and national economies.
