The Chehalem Mountains AVA is a single uplifted landmass southwest of Portland in the northern Willamette Valley, extending 20 miles in length and 5 miles in breadth, stretching from southeast to northwest. They include several discrete spurs, mountains and ridges, such as Ribbon Ridge and Parrott Mountain. The highest point within the Willamette Valley is the Chehalem Mountains’ Bald Peak, at 1633 feet, which affects weather for the AVA and for adjoining grapegrowing hillsides. It is the geography and climate that differentiate this AVA from others. All three important hillside soil types are represented, basaltic, ocean sedimentary and loess (blown lake bed sediment), the predominant soil on the northern face of the Chehalem Mountains. Within the almost 70,000 acres of this AVA are over 1600 acres of grapes, grown in over 100 vineyards, and 31 wineries.

Ribbon Ridge AVA is a very regular spur of ocean sediment uplift off the northwest end of the Chehalem Mountains, containing a relatively uniform 5 1/4 square miles (3350 acres) of land.  Approximately 500 acres are currently planted on the ridge, within 20 vineyards.  The AVA is distinguished by uniform, unique ocean sedimentary soils and a geography that is protected climatically by the larger landmasses surrounding it. Paucity of aquifers forces most vineyards to be dry farmed. Ribbon Ridge is contained within the larger Chehalem Mountains AVA.   www.ribbonridge.org
