(TeatroNaturale) - Washington wine industry is just becoming stronger. A new study launched last month by Stonebridge Research of St. Helena (California) reveals just how shiny is the WA wine industry. The research requested by Washington State Wine Commission, a wine marketing group created and financed by member grape-growers and vintners, reveals that Washington wine industry leads to $8.6 billion yearly to the state economy and nearly 30,000 wine jobs. That's almost three times more from 2006 when similar study has been done.
