Yamhill-Carlton District is a sub-appellation of the Willamette Valley AVA. It's located 35 miles southwest of Portland and 40 miles east of the Pacific Ocean and includes the hamlets of Carlton and Yamhill.
60 vineyards, 20 wineries, 1,200 acres of grapes
The Yamhill-Carlton District is protected by high elevation areas to the west (Coast Range), north (Chehalem Mountains) and east (Dundee Hills), which results in less rain than surrounding areas and moderate growing conditions perfectly suited for cool-climate grapes, including the area's signature variety: Pinot noir.
Yamhill-Carlton is comprised of coarse-grained, ancient marine sedimentary soils, over sandstone and siltstone, that drain quickly, making them ideal for viticulture. Grapes grown in such soil often result in wines lower in acid than those made from grapes grown in basaltic or wind-blown soils.
Yamhill-Carlton vineyards grow on sites with elevations between 200 and 1,000 feet, avoiding low valley frost and high elevation temperatures unsuitable for effective ripening. Geographically, this area is protected by the Coast Range to the west, the Chehalem Mountains to the north and the Dundee Hills to the east.
Pinot noir (82%), Pinot gris (7%), and Chardonnay (4%) account for 93% of the planted acreage in the Yamhill-Carlton District.
