Chehalem Mountains AVA
Location: Chehalem Mountains is contained within the Willamette Valley AVA. This viticultural area is 19 miles southwest of Portland and 45 miles east of the Pacific Ocean. It is 20 miles in length and 5 miles wide.
Wine history: Chehalem Mountains’ winegrowing history dates back to 1968 when UC Davis refugee Dick Erath purchased 49 acres on Dopp Road in Yamhill County. He aptly called the property Chehalem Mountain Vineyard. By the mid to late 1970s, there was a patchwork of vineyards in the area, including those owned by such modern wine pioneers as the Adelsheims and the Ponzis. Over the next three decades other reputable winegrowers planted roots in the area. The appellation was approved in the late fall of 2006.
Climate: Chehalem Mountains’ elevation goes from 200 to 1,633 feet, resulting in varied annual precipitation (37 inches at the lowest point and 60 inches at the highest) as well as the greatest variation in temperature within the Willamette Valley. These variations can result in three-week differences in the ripening of Pinot noir grapes.
Soils: Chehalem Mountains has a combination of Columbia River basalt, ocean sedimentation and wind-blown loess derivation soil types.
Topography: Chehalem Mountains is a single landmass made up of several hilltops, ridges and spurs that is uplifted from the Willamette Valley floor. The appellation includes all land in the area above the 200-foot elevation. They are the highest mountains in the Willamette Valley with their tallest point, Bald Peak, at 1,633 feet above sea level.
