Our Winery

TwiningVine is a boutique family winery nestled among the rolling hills and oak forests of Cull Canyon near Castro Valley, California. Established in 2003 by Teddy and Keith Seibert, TwiningVine produces Cabernet Franc, Cabernet Sauvignon, Chardonnay, Merlot, Sangiovese, Sauvignon Blanc, Syrah and Zinfandel from grapes grown at the winery estate.


Spanning ten acres, the historic property was originally home to a booming sawmill followed by a horse ranch. Over the last decade, the land has gracefully transformed into a winery and venue for weddings, retreats, private parties and other events. While maintaining the heritage of the property, we promote a balanced environment for people, land and animals. Oak-shaded expanses, a meandering creek, vineyards, picnic areas, a bocce court and horse shoe pitch invite visitors to celebrate, laugh, linger and relax. 


TwiningVine is a proud member of the Livermore Valley Winegrowers Association.
