Home of the first Pinot noir vineyard of the Willamette Valley, planted by David Lett of Eyrie Vineyard in 1966, today the Dundee Hills AVA remains the most densely planted AVA in the valley (and state). To its north sits the Chehalem Valley and to its south, runs the Willamette River. Within the region’s 12,500 acres, about 1,700 are planted to vine on predominantly basalt-based, volcanic, Jory soil.
