(Wines&Vines) - Winery clusters can bolster regional economic resilience, according to new research from Walla Walla Community College in partnership with Economic Modeling Specialists Inc. (ESMI) of Moscow, Idaho. Based on experience in Walla Walla, the research suggests that Oregon’s Umpqua Valley could see 56% growth by 2020, if its development mirrors that of Walla Walla. The number of wineries could rise to 108 by 2020—up from 70 today—while generating 1,293 jobs. The projected employment includes 914 direct jobs in the wine industry, up from the current 579.
