Siltstone Wines sources Oregon Pinot noir and Pinot gris from Guadalupe, a 40-acre vineyard owned by Jim Stonebridge and Kathleen Boeve and currently leased to Ken Wright Cellars. Wine grapes were first planted in 1989 and Vinetenders has managed the site since then, coordinating the design, planting and daily management.
Guadalupe Vineyard is located in the Dundee Hills AVA. However,the soils are not typical of this appellation. The soils at Guadalupe are marine sedimentary, mainly silty and sandy loams, while those found in the Dundee Hills are heavier clay loams. Spaced at 7' x 5', it is planted to the Wädenswil, 777 and Pommard clones. The elevation is between 350'-450', and produces dark colored, intensely flavored fruit.
Blacktail Vineyard is located at the Myers' family home place. The 40 acre farm is planted to 15 acres of Pinot noir, Pinot gris, and Mueller-Thurgau and Temperanillo. The rest of the farm is forested and in pasture. Planting began in the late 1990's, and has since been home to various viticultural experiments in trellising and vine training. Clonal and rootstock selection, along with well-drained Woodburn soils and ample North Valley hea help this site to produce high quality fruit even in the most challenging vintages. This vineyard is certified by the Food Alliance.
