Since 1994, Steve and his son Ned have also been growing grapes on their family owned Parmelee-Hill Vineyards. Steve Hill and his wife Gwen Parmelee Hill purchased the first parcel of their Parmelee-Hill Vineyards property in 1994 and planted it with Syrah. In subsequent years Steve and Gwen purchased adjoining acreage, piecing together what is today the 70 acre Parmelee-Hill Vineyard.
Parmelee-Hill Vineyards lies in the Southwest corner of the Sonoma Valley Appellation, a stones throw from the Carneros line. The unique Parmelee-Hill site allows the propagation of Syrah and Zinfandel on southwest and eastern facing slopes and Pinot Noir, Chardonnay, and Roussanne on the exposed rock and clay flats.
