The 2,400-foot Sonoma Mountain range rises above the town of Glen Ellen, at the western edge of the Valley of the Moon. Found here are highaltitude, steep-sloped vineyards including the Four Brothers/Sullivan Vineyard which is farmed by Jim Sullivan and his sons including Patrick and Mike, who is the winemaker at Benovia and formerly of Hartford Court. Straddling the Bennett Valley and Sonoma Mountain AVAs, Sullivan Vineyard encompasses eleven acres along a ridge at an elevation of 750-900 feet where the irregular folds and crevices of the mountain create a unique microclimate, ideal for cool climate Pinot Noir. The vineyard is streaked with a variety of well-drained soil material including Sprekles clay and volcanic material. These vineyard hillsides are planted to Pinot Noir clones 777, a Vosne Romanée suitcase clone and Pommard.
