Donnachadh Vineyard

Donnachadh Vineyard

Family owned and organically farmed, Donnachadh Vineyard is located on Santa Rosa Road, in the Sta. Rita Hills AVA of Santa Barbara County. The property is 285 acres with approximately 40 acres under vine. We grow Pinot Noir, Chardonnay, Syrah and a little bit of Gamay Noir.


The climate of the Santa Rita Hills is dominated by the Pacific Ocean, which lies about 9 miles from the vineyard. Morning fog cools the grapes and consistent afternoon ocean breezes keep heat from building up over the course of the day.


The vineyard consists of two main parts: the hillside blocks, and the riverside blocks. The riverside blocks sit alongside the Santa Ynez River. They are more sheltered from the wind than the hillside blocks and the soil is a delicate and well drained sandy loam that sits on top of deep layers of gravel river deposits. The hillside blocks are more exposed to the ocean winds. The soil there is derived from marine shale deposits and features more clay, rocks and cobbles than the riverside blocks. Overall, the hillside environment is quite challenging for the vines, limiting yields and producing grapes of exceptional character.
