viticulture

| Oregon's Growing Viticulture Industry |

 

Oregon's winegrape acreage and production has grown by 67% since 2000. The growth has occurred in five diverse growing regions throughout the state: Willamette Valley, Umpqua, Rogue, Applegate and Illinois Valleys, Columbia Gorge and eastern Oregon's Walla Walla Valley. This increase in acreage has been due to the state's reputation for fine wine production and increasing demand for high quality grapes and wines. Oregon State University research and extension faculty have contributed to the growth in wine grape acreage by conducting critical research that keeps winegrape producers and wineries competitive in the local, regional, national and world wine market.

OSU’s Viticulture Research Program is a collaborative effort involving faculty in multiple departments (Horticulture, Crop and Soil Science, Botany and Plant Pathology and Agriculture Economics) and USDA-ARS researchers. The program focuses on both applied and functional components of viticulture. Research is conducted to understand vine physiology, vineyard management practices and vineyard ecosystems and to address fruit and wine quality, disease and pest incidence, and sustainability of farming systems.
