They focus on cool-climate Pinot Noir from Green Valley, the coldest region of the famed Russian River Valley. Fog flows from the Pacific Coast along the Russian River and through the Petaluma Wind Gap, converging on this small area. Orogeny's grapes are grown on five small vineyards, each only five to ten acres, which were selected to display the bright fruit characteristics of classic Green Valley Pinot Noir. Their limited size permits Orogeny to use hands-on farming techniques. The vines are planted on ridges in Gold Ridge soils, a mix of sandy loam over sandstone and clay. These sites provide excellent drainage, which promotes even ripening and concentrated flavors.
