The Willamette Valley AVA (American Viticultural Area) is a prominent wine-producing region located in the state of Oregon. Established in 1984, it is known for its diverse microclimates and rich volcanic soil, which contribute to the cultivation of high-quality grapes. The valley is particularly famous for its Pinot Noir, but also produces other varietals like Pinot Gris and Chardonnay. Spanning approximately 150 miles from north to south, the Willamette Valley is bordered by the Coast Range to the west and the Cascades to the east. The region's climate is characterized by cool, wet winters and warm, dry summers, making it ideal for grape growing. With over 500 wineries, the Willamette Valley is a key player in the U.S. wine industry.
