About Us / Testarossa Vineyards History: Testarossa Winery, located in the historic Novitiate of Los Gatos, approximately sixty miles south of San Francisco, was founded by husband and wife team of Rob and Diana Jensen. Leaving high-tech careers behind, they started Testarossa by producing 25 cases in their garage. Today, Testarossa produces over 15,000 cases annually, and we have earned hundreds of 90-point-plus scores on our wines from all the top wine publications. The name Testarossa (Italian for "red-head") was a nickname given to Rob when he was a university student in Italy.
