Holstein Estate Vineyard

Granville Wine Co. began with the estate vineyard where Jackson grew up, which Jackson and Ayla now tend as their own. The Holstein Estate Vineyard sits on the eastern edge of the Dundee Hills AVA at an elevation between 615 and 740 feet. Gently sloping toward the lush valley below, the high-elevation vines receive plentiful sun and cool winds from the Pacific give the vines a much-needed respite at night, leading to slow and balanced fruit development.

Situated on Jory soils with a fractured volcanic basalt bedrock, the vineyard blocks face every point on the compass, adding to the diversity and uniqueness of the terroir. Its Jory soils were formed millions of years ago, when lava flowed over what is now the Willamette Valley, leaving behind a now-famous red clay soil series called Jory. These soils have unique water-holding capacity so the Holstein Estate Vineyard can be dry-farmed and the vines are then encouraged to send their roots very deep into the ground.

Originally planted in 1972, the Holstein Estate Vineyard was one of the earliest plantings in the Willamette Valley, when the region was more known for hazelnuts than wine. The site’s unique position along a ridge in the Dundee Hills has proven to create complex, beautiful fruit that lends itself to Old World, Burgundian style wines. The original vines have been incrementally replanted since the 1990s, with vines on the property now ranging between 17 and 32 years old. Planted with Old World clones of Pinot Noir, the vineyard is meticulously monitored and maintained by Jackson and his crew. The site is free of all synthetic herbicides, fertilizers, and any other foreign substances that they wouldn’t feel comfortable using around their family. Jackson leads a team of three year-round employees who manage the vineyard, making decisions together that will ultimately guide the wines in the cellar, with a depth of generational knowledge and the curiosity to learn from every vintage.

Koosah Vineyard

Koosah Vineyard is farmed Biodynamically at a high elevation of 700 to 1100 feet, the highest elevation in the Eola-Amity Hills AVA. Kevin and Carla Chambers sold their first vineyard (in Yamhill-Carlton) to Résonance Winery in 2013, and then they planted Koosah, eventually selling this vineyard as well to Résonance after years of producing award-winning fruit. Granville sources both Pinot Noir and Chardonnay from this special site, farmed regeneratively since it was planted. The Chardonnay is planted at the steepest site at the top of the vineyard. The high elevation and exposure to coastal winds creates beautiful, complex fruit.

Temperance Hill Vineyard

Temperance Hill was first planted in 1981 on what was believed to be remnants of an ancient volcano. The vineyard has been managed by Dai Crisp since 1999, who implemented organic farming techniques and became certified in 2012, and certified Salmon Safe in 2005. Granville sources two acres exclusively from the “North Block” of the property which sits at 820 ft elevation with both pommard and dijon clone 777.

Knudsen Vineyard

Managing Knudsen Vineyard was one of Jackson’s father’s first jobs in the Oregon wine industry in the 1970s, so making wine from this fruit means coming full circle for Jackson. 

Knudsen Vineyard has been a flagship vineyard for Argyle Winery since 1987, and is now run by a second generation of the Knudsen family. 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. Granville’s “Old Vine” Pinot Noir is sourced from Block 2, Pommard clone Pinot planted in 1974 and still own-rooted.
