St. Amant Vineyard / Jackson Valley, Amador County
Originally farmed and planted in 1972 to own-rooted Zinfandel, St Amant in the late 1970s St Amant became interested in Portuguese port wines, and grafted over a section to five Portuguese varieties. Bastardo/Trousseau, one of the few varieties UC Davis had at the time, had their first crop in 1981. In 1994 they replanted their port varieties on resistant rootstock due to a spell of phyloxera. The 1.8 organically farmed acres of Rootdown were replanted in 2004 on 3309 rootstock; rows are planted on an east/west orientation, 8 X10 spacing, on a vertical shoot position trellis. Soil in the vineyard is Honcut, a series that consists of very deep, well drained soils that formed in moderately coarse textured alluvium from basic igneous and granitic rocks. The soils are on floodplains and moderately sloping alluvial fans and have slopes of 0 to 9 percent. The mean annual precipitation is about 12 inches and the mean annual air temperature is about 62 degrees F.
Jane’s Vineyard / Hopland, Mendocino County

The Talmage series consists of very deep, somewhat excessively drained soils formed in alluvium from mixed sources. Talmage soils are on alluvial fans and plains and have slopes of 0 to 9 percent. The mean annual precipitation is about 40 inches and the mean annual temperature is about 57 degrees F.
Dry Bone Ranch / Fiddletown, Amador County

The mean annual precipitation is about 45 inches and the mean annual temperature is about 50 degrees F.
