About Grindstone Wines
Grindstone Wines is a family winery in the Dunnigan Hills near Esparto, where estate vineyards ride the warm, breeze-cooled slopes that define Yolo's northern wine country.
Public tasting and events run with booking details to verify, and the winery's official directions page is the reliable route in, the farm-road geography defeats casual navigation.
The Dunnigan Hills setting delivers the county's biggest vineyard views; verify the booking, use the official directions, and let the hills do the rest.
