High Rock Ranch (HRR) Vineyard is in the Yorkville Highlands appellation. HRR is ~5 miles southeast of Boonville on Highway 128. The vineyard is located 17 miles from the pacific coast. The property is clouded in morning fog during the spring and summer months. The fog typically burns off in the early to mid-morning hours followed by warm summer month temperatures. The vineyard’s consistent large daily temperature differential, rocky soil, west facing slopes and 1,100’ elevation provides for ideal for growing conditions and extraordinary grapes. The vineyard is watered by a designated lake located on the property. There is an abundance of water. High Rock Ranch Vineyards’ conception began when we were approached by Wells Guthrey. Wells informed us that the property was an ideal for growing Syrah. Wells believed that with his play book, he could make a world class Syrah. Copain has been making a High Rock Ranch VD Syrah every year since 2007. Siduri began making wine from our Pinot Noir with our first harvest in 2022. Proof of concept of our Pinot Noir may be found from our immediate neighbor’s, Williams Selyem Weir Vineyard Pinot Noir .
