Willamette Valley

The Willamette Valley Viticultural Area lies in the Willamette Valley of Oregon. At 5,200 square miles (13,500 km2), it is the largest AVA in the state, and contains most of the state's wineries; The Willamette Valley AVA was established in 1984, and since then six  smaller AVAs have been created within the northern portion of Willamette Valley (Dundee Hills, probably the best known, Chehalem Mountains, Eola-Amity Hills, McMinnville, Ribbon Ridge, and Yamhill Carlton ).

Its soils, rich in volcanic and glacial deposits are ideal for wine-growing. This combines with the Willamette Valley’s relatively mild climate: cool, wet winters and warm, dry summers.

The region's terroir provides some of the best conditions for growing Pinot Noir. Although Williamette Valley is worldwide acclaimed for their production of Pinot Noir wines, it also produces such varietals as Pinot Gris, Pinot Blanc, Chardonnay, Riesling, Gewurztraminer, Sauvignon Blanc, and limited quantities of Cabernet, Merlot and Syrah.
