Oak Knoll District of Napa Valley


In 1968, the Trefethen family purchased seven farms surrounding a magnificent, but run-down, 19th-century winery in southern Napa Valley and created Trefethen Family Vineyards. At the time, there were fewer than 30 working wineries in the Napa Valley.



We take special pride in the stature and recognition as a winegrower and wine producer that we have gained both nationally and internationally as winegrowers since 1970 and wine producers since 1980.


Blackbird Vineyards

Since 1999, the Blackbird Vineyardquietly provided fruit to many of Napa’s finest winemakers, for whom it yielded astonishing comments from Napa Valley veterans and noteworthy editorialists. Purchased by Michael Polenske in 2003, Blackbird Vineyards is now an ultra premiumlabel in its own right.
