Oregon’s wine industry, renowned for its premium wines and diverse grape cultivars, continues to rank among the top in the nation. Since the onset of commercial production in the 1960s, the state has risen to become the fourth-largest wine producer in the United States, following California, Washington, and New York.
The state encompasses 23 American Viticultural Areas, with key production zones in the Willamette Valley, Southern Oregon, Columbia Gorge, and Eastern Oregon’s Walla Walla Valley. This geographical diversity supports a broad range of wine styles and grape varieties, enhancing Oregon’s reputation in the global market.
In 2022, Oregon’s wine industry contributed an estimated $8.17 billion to the state’s economy, supporting approximately 39,437 jobs. Wine-related tourism added a further $758 million in revenue and sustained 8,806 jobs. The year also marked a historic high for wine grape harvests, with a record 137,065 tons produced from more than 44,000 acres of vineyards and over 1,100 wineries across the state. A focus on premium wine production enables Oregon to generate above-average returns per ton and higher revenue per case compared to national averages.
Despite this success, the industry faces mounting challenges. Wildfire smoke threatens grape quality, while climate change — in the form of rising temperatures and shifting precipitation patterns — affects vine health and fruit development. Grapevine diseases and pests pose additional risks to yield and wine quality. Economic pressures, including increasing labor costs and declining sales, further strain the viability of vineyard and winery operations.
In response, Oregon State University (OSU) plays a critical role in supporting the industry’s resilience through research and outreach conducted by its Agricultural Experiment Station and Extension Service. The Oregon Wine Research Institute (OWRI), housed within OSU’s College of Agricultural Sciences, brings together experts in viticulture, enology, plant pathology, entomology, and agricultural economics to address the sector’s most urgent issues.
One major area of focus is grapevine red blotch disease, which interferes with berry ripening and reduces wine quality. Researchers from OSU and the U.S. Department of Agriculture’s Agricultural Research Service have identified insect vectors, developed diagnostic tools to monitor the disease’s spread, and created best practices to manage its impact in both vineyards and wineries.
To mitigate the effects of wildfire smoke exposure on grape and wine quality, OSU has assembled a multidisciplinary research team. Their work has led to the identification of smoke-related compounds and the development of preventative measures, including vineyard sprays and winemaking techniques designed to reduce the presence of undesirable flavors in the finished product.
Further OWRI research explores the influence of microbial activity on wine aroma and spoilage. This work provides winemakers with critical insights into managing fermentation and storage conditions to maintain high product quality.
In support of sustainable viticulture, OSU Extension faculty conduct applied research and develop outreach tools that promote grapevine health. By enhancing the understanding of vine physiology and adapting science-based practices to Oregon’s unique climate, they help growers make informed, cost-effective decisions throughout the growing season.
OSU’s contributions to viticulture and enology span decades. Historic achievements include importing Dijon clones of Pinot noir and Chardonnay to the U.S., isolating malolactic bacteria capable of thriving in cold, acidic conditions, and hosting the inaugural International Cool Climate Symposium for Viticulture and Enology in 1984.
Through campus-based and statewide Extension services, OSU provides industry stakeholders with comprehensive support. This includes personalized consultations, newsletters, web resources, workshops, and field days tailored to grape growers and winemakers of all experience levels.
By addressing emerging threats and enhancing production practices, OSU ensures that Oregon’s wine industry remains competitive, sustainable, and equipped to thrive in a changing global landscape.
