Willamette Valley (Template:IPAc-en Template:Respell) is an American Viticultural Area (AVA) which lies in the Willamette Valley of Oregon. The AVA is the wine growing region which encompasses the drainage basin of the Willamette River. It stretches from the Columbia River in the north to just south of Eugene in the south, where the Willamette Valley ends; and from the Oregon Coast Range in the west to the Cascade Mountains in the east. At Template:Convert, it is the largest AVA in the state, and contains most of the state's wineries; approximately 908 as of 2021.

The AVA was established by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury on January 3, 1984 after reviewing the petition submitted by Mr. David B. Adelsheim, Chairman, Appellation Committee, Oregon Winegrowers Association, and owner of Adelsheim Vineyards, proposing a viticultural area in northwest Oregon, as part of the Willamette River Basin, to be known as "Willamette Valley."[1] Since then, ten distinctly featured areas, referred as "sub-AVA" or "sub-appellation", were recognized within the Willamette Valley AVA, with nine of them in the northern region and the Lower Long Tom AVA in the southern.[2] The Willamette Valley has a cool, moist climate, and is recognized worldwide for its Pinot noir.[3]

Although not officially recognized, many wine connoisseurs further define the Willamette Valley into northern and southern regions with the demarcation being the latitude of Salem (approximately 45° north).[4]

Climate

The Willamette River Valley

The climate of Willamette Valley is mild year-round. Winters are typically cool and wet, summers are dry and warm; heat above Template:Convert only occurs 5 to 15 days per year, and the temperature drops below Template:Convert once every 25 years. Most rainfall occurs in the late autumn, winter, and early spring, when temperatures are the coldest. The valley gets relatively little snow (Template:Convert to Template:Convert) per year.[5] The hardiness zone is mostly 8b.[6]

Not all portions of the Willamette Valley are suitable for vineyards, however, and the largest concentration of wineries is found west of the Willamette River, on the leeward slopes of the Coast Range, or among the numerous river and stream valleys created by Willamette River tributaries. By far, the largest concentration of wineries is in Yamhill County.[7]

Sub-appellations

There are ten American Viticultural Areas within the Willamette Valley AVA. These smaller AVAs recognize regions within the larger Willamette Valley AVA that have distinctive climate, soil, elevation, or other physical features that make them noteworthy for wine production.

Chehalem Mountains AVA

Template:Main article The Chehalem Mountains AVA, established in 2006, stretches Template:Convert from Wilsonville in the southeast to Forest Grove in the northwest. The Chehalem Mountains includes Ribbon Ridge, Parrett Mountain, and Bald Peak. The petition process for the creation of the AVA began in 2001 and was led by David Adelsheim of Adelsheim Vineyard.[8] It contains two sub-regions, Laurelwood District AVA and Ribbon Ridge AVA.

Dundee Hills AVA

Template:Main article Dundee Hills AVA lies in the hills northwest of Dundee encompassing about Template:Convert cultivating Template:Convert of grapes. Over 25 wineries and independent vineyards in this region produce over 44,000 cases of wine. The area is particularly noted for its Pinot noir; several wineries in the AVA have won international recognition for their wines.[9][10]

Eola-Amity Hills AVA

Template:Main article The Eola-Amity Hills AVA stretches from the town of Amity in the north to Salem in the south within Polk and Yamhill Counties. The hills cover an area west of the Willamette River approximately Template:Convert long by Template:Convert wide. The Eola-Amity Hills area benefits from steady winds off the Pacific Ocean that reach the Willamette Valley through the Van Duzer corridor, a gap in the Oregon Coast Range, moderating the summer temperatures. The name Eola is a tribute to the windy conditions in the area, and is derived from Aeolus, the Greek god of wind.[11]

Laurelwood District AVA

Template:Main article The Laurelwood District AVA is located west of the city of Portland and lies entirely within the Willamette Valley and Chehalem Mountains AVAs since it was established by the TTB in May 2020. It covers approximately Template:Convert and contains 25 wineries and approximately 70 commercially-producing vineyards that cover a total of approximately Template:Convert. The distinguishing feature of the Laurelwood District is the predominance of the Laurelwood soil series.[12]

Lower Long Tom AVA

Template:Main article The Lower Long Tom AVA was established in 2021. It is located in the southern Willamette Valley in Lane and Benton Counties, near the towns of Junction City and Monroe.[2] Its coverage is approximately Template:Convert and contains 12 wineries and 24 commercially-producing vineyards that plant approximately Template:Convert. As of 2022, the Lower Long Tom is the only nested appellation located in the southern Willamette Valley AVA, in contrast to nine nested appellations in the north.[13] The region is primarily known for its Pinot noir and Pinot gris.[2]

It encompasses approximately Template:Cvt and contains 10 commercial vineyards cultivating about Template:Cvt under vine with two wineries. The viticultural area surrounds Mount Pisgah (Template:Langx, pisgá: literally means "summit"), formed 65 million years ago as a sea floor volcano, covered by marine sediment and pushed up out of the ocean, among the hills of the Willamette Valley rising Template:Convert from the foothills to its peak. The long name was assigned to avoid confusion with another "Mount Pisgah" in a different county or state.[16][15]

Ribbon Ridge AVA

Template:Main article The Ribbon Ridge AVA, between Newberg and Gaston, is a ridge containing uplift of ocean sediment. It lies at 45° 21' N, 123° 04' W, at the northwest end of the Chehalem Mountains. The name originates in the 19th century.

The AVA was established in 2019.[19]

Yamhill-Carlton District AVA

Template:Main article The Yamhill-Carlton District AVA is located in the area surrounding the towns of Yamhill and Carlton.
