Rob and Diana Jensen, two Santa Clara University engineering graduates, started Testarossa in 1993 and moved into the Novitiate winery in 1997. The name is Italian for “red head,” Rob’s nickname in Italy. It is known mainly for Chardonnay and Pinot Noir.
Its Bistro 107 is named for the bond number the Jesuit winery received in 1888, and since 2013 the winery has held a yearly Blessing of the Grapes with the retired Jesuits next door.
