That is a long time (in American wine history) to be working one place (Pritchard Hill). It was so long ago that Donn Chappellet and his wife Molly listened to the advice of renowned winemaker Andre Tchelistcheff and purchased the property overlooking Lake Hennessey. They recently celebrated their 50th year in Napa Valley.
It is considered to be the first Napa winery to produce their grapes from a vineyard at elevation and now a second generation is running the operation. Donn Chappellet passed in May 2016.
The winery is considered to be one of the Napa’s hidden treasures. Chappellet Winery sits in the eastern hills above the valley and the town of St Helena. Their wines are consistently rated very highly. Tastings are arranged by appointment only, so try knocking on their door.
