Oak Knoll does not have its own vineyards, instead purchasing grapes from area Willamette Valley grape producers.[3]
History
The winery was established in 1970 by Marjorie and Ron Vuylsteke south of Hillsboro on what was formerly a dairy farm.[4][5] The couple first started making wine in their garage, after they had a bumper crop of blackberries.[4] At the time, Ron was an electrical engineer.[4] As they became more successful in making wine, they started their business with financial backing from a silent partner.[4]
It was the first winery in Washington County.[1][3] In its early years, the winery used repurposed Coca-Cola drums for storing the wine during the fermentation process.[5] The first batch consisted of 4,000 gallons of blackberry fruit wine. The winery's first Pinot noir was produced in 1973.[3] Chardonnay and Riesling were introduced in 1975 and Pinot gris was first produced in 1990.[3]
Oak Knoll was the first winery in Washington County to open a tasting room.[5] By 1986, the winery was the second-largest by volume sold in Oregon,[6] but slipped to third by 1988.[7] The Washington Post named the winery's Pinot noir some of the best Pinot noir from the United States in 1986.[8] Oak Knoll produced other fruit wines, such as loganberry, and in 1998, its Oak Knoll raspberry "Frambrosia" was named one of the world's best dessert wines in USA Today.[9][10] In 2005, the Vuylstekes sold part of the winery to their sons Tom and John.[11] In 2006, the winery was the largest in Washington County with 30,000 cases produced each year.[12]
Business
Oak Knoll uses grapes from within the Willamette Valley AVA to produce its wines. The winery is a family-run enterprise with Greg Lint serving as president until his death in September 2022.[13] As of 2007, it had annual revenues of $7.5 million, selling varieties including Chardonnay, Pinot noir, Niagara, and Pinot gris under its own label as well as under the Twilight Blush, Eruption, and Frambrosia labels.[13] The winery is the official wine sponsor of the Portland Rose Festival.[14][15]
