Luxury Vineyard Views If you were able to design a perfect vineyard landscape, it would look largely like our property, Port de Grace. The highest point is North with East, South and West facing slopes as it sits 100 ft above the Snake River. The Snake River runs East-West below the property yielding a light saturation not seen in normal settings. We are offering 14 acres of fertile land for sale with the main house not included in the sale.
