Oregon’s Willamette Valley is renowned for its picturesque landscapes and exceptional wines. Nestled between the Cascade Mountains and the Coast Range, this region spans over 5,000 square miles from Portland to Eugene, and offers a unique climate and terroir that contribute to the production of world-class wines, particularly Pinot Noir. The over-arching American Viticultural Area is more than 100 miles long and 60 miles wide, *representing 3,438,000 acres. In this post, we will explore the Willamette Valley’s wine regions and its designated American Viticultural Areas (AVAs).

The Willamette Valley’s wine scene continues to evolve, with new AVAs being established to further highlight the unique characteristics of this renowned wine-producing region. Understanding these developments helps wine enthusiasts appreciate the diversity and complexity of wines from the Willamette Valley.
In 2002, a collaborative initiative by local vineyards and wineries led to a significant reorganization of the northern Willamette Valley AVA. Petitions were submitted to the Alcohol and Tobacco Tax and Trade Bureau (TTB) to establish more specific AVAs that could better highlight the distinctiveness of wines produced in this region. As a result, six AVAs were delineated: Chehalem Mountains, Dundee Hills, Eola-Amity Hills, McMinnville, Ribbon Ridge, and Yamhill-Carlton.
Chehalem Mountains AVA – The Chehalem Mountains AVA is a single uplifted landmass and includes several discrete spurs, mountains and ridges, such as Ribbon Ridge and Parrett Mountain. At the Willamette Valley’s highest point, Bald Peak (at 1,633 feet) affects weather for the AVA and for adjoining grape growing hillsides, differentiating itself from others. With three hillside soil types represented: basaltic, ocean sedimentary and loess.
Dundee Hills AVA – Known for its red volcanic Jory soil, Dundee Hills is celebrated for producing Pinot Noir wines with bright fruit flavors and earthy undertones. The region’s relatively warmer climate allows for early ripening, contributing to the wine’s rich and complex profile.
Eola-Amity Hills AVA – This AVA benefits from the cool marine winds that flow through the Van Duzer Corridor, creating a climate that favors the production of wines with vibrant acidity and depth. Eola-Amity Hills is recognized for its expressive Pinot Noir and crisp Chardonnay.
McMinnville AVA – McMinnville is known for its rugged terrain and unique basalt-based soils. The AVA’s cool climate results in wines with intense flavors and firm structure. Pinot Noir from McMinnville is often described as having notes of black fruit and a distinctive mineral quality.
Ribbon Ridge AVA – As the smallest AVA in the Willamette Valley, Ribbon Ridge boasts a microclimate that is ideal for growing Pinot Noir. The combination of well-drained sedimentary soils and a protected environment results in wines with concentrated flavors and silky textures.
Yamhill-Carlton AVA – Located in the rain shadow of the Coast Range, Yamhill-Carlton enjoys a warmer and drier climate compared to other parts of the valley. The marine sedimentary soils in this area impart a distinctive spiciness and dark fruit character to the wines, particularly Pinot Noir.
Each of these regions is celebrated for their unique terroir and the distinct flavors they impart to the wines. The expansion did not stop there.
RECENT ADDITIONS:
With a continued focus on recognizing the uniqueness of different subregions, several more AVAs have been established. The Van Duzer Corridor, Tualatin Hills, Laurelwood District, Lower Long Tom, & Mount Pisgah, Polk County Oregon AVAs.
