Idell Family Vineyards, founded in 2005 by Susan Kornblatt Idell and Richard Idell, is well-known for producing Sonoma Valley premium grapes and wines. The vineyards are located within both the Sonoma Valley and Sonoma Coast AVAs. Idell Family Vineyards has partnered with viticulturist and vintner Steve Matthiasson of Napa to develop an ultra-premium Chardonnay vineyard, the Michael Mara Vineyard®. In addition to producing their own Chardonnay wine from this world-class site, Susan and Richard sell Chardonnay grapes to six other premium wineries that handcraft small lots of vineyard-designate wines. In addition, Idell Family Vineyards produces their own Oscar® line of red wines; Syrah; and a traditional dry-farmed field blend of Zinfandel, Petite Sirah, Carignane, Mourvedre and Grenache, all harvested and co-fermented as an Oscar® Mixed Black.
