Dundee Hills AVA

Dundee Hills AVA occupies a compact set of rounded hills in Oregon's northern Willamette Valley, rising above surrounding valley floors near the towns of Dundee and Dayton. Vineyard slopes generally sit at moderate elevations and form a recognizable island of upland terrain.

The Coast Range provides partial shelter from direct Pacific weather, while the Willamette Valley's cool, wet winters and dry summers shape the season. Elevation reduces frost risk relative to valley floors in some locations, and slope direction affects sunlight, wind, and ripening.

Deep, weathered volcanic soils of the Jory series are the appellation's best-known feature. Their iron-rich clay texture and water-holding behavior differ from the marine sedimentary and windblown soils prominent in several neighboring AVAs, although individual sites still vary.

Pinot Noir is the principal grape and the foundation of the area's international reputation. Chardonnay, Pinot Gris, Pinot Blanc, and traditional-method sparkling wines also have important roles, generally emphasizing acidity, fruit clarity, and moderate structure. Dundee Hills is nested within Willamette Valley AVA. Graph links should connect both origins while also exposing vineyard, elevation, soil, grape, producer, vintage, and wine. Volcanic soil is a useful relationship, not a guaranteed sensory profile. Neighboring AVAs provide further useful comparative context.
