TwiningVine
TwiningVine, est. 2003 is Castro Valleys only local family estate vineyard and winery!
We are nestled on 10 acres surrounded by the rolling hills and forest land of Cull Canyon.
Originally a sawmill took residence on the property and overtime the land transitioned to cattle and horse ranches. The circa 1880’s “Red Barn” still stands which was constructed with square nails and redwood. Today the land has gracefully become home to our estate winery where we proudly grow and produce our own wines. All of our vineyards are environmentally sustainable and we have been dry farming since 2008. The varietal of grapes grown and produced are Cabernet Franc, Cabernet Sauvignon, Chardonnay, Merlot, Sangiovese, Sauvignon Blanc, Syrah, Tempranillo and Zinfandel.
The unique micro climate within Cull Canyon has led us to produce award winning wines. Our red varietals tend to be lighter than what you would find in the warmer valleys but have very diverse flavors that are true and stand well on their own. Our white varietals grow well in the canyon and are smooth by nature.
Our small estate winery produces approximately 1000 cases of wine per year. We strive to maintain the heritage of the property and actively support balance for people, land and nature.
TwiningVine is a proud member of the Livermore Valley Winegrowers Association.
