The Ribbon Ridge AVA is an American Viticultural Area in Yamhill County Oregon. It is the smallest AVA in Oregon and is entirely contained within the Chehalem Mountains AVA which in turn is entirely contained within the larger Willamette Valley AVA. Ribbon Ridge stretches between the towns of Newberg and Gaston. The ridge is defined by local geographic boundaries and an uplift of ocean sediment.
