Established in 1971 by Oregon wine industry pioneer Cal Knudsen and his wife Julia Lee, Knudsen Vineyards is one of Oregons oldest and largest family-owned vineyards. It is also the original site of Bonded Winery No. 52, the first commercial winery in the Dundee Hills. The 130-acre vineyard in the heart of the Dundee Hills AVA includes a mix of old-vine blocks and new high-density blocks planted with Old World Dijon clones. Knudsen Vineyard was a primary supplier of grapes to Knudsen Erath Winery from 1975 through 1986 and has been a leading supplier of fruit to Argyle Winery since 1987. In 2014, the Knudsen family returned to winemaking under its own label, and in 2020 they opened The Outlook at Knudsen Vineyards tasting room.
