'In 1972, Ridge made its first Lytton Springs from vines planted on the eastern half of the vineyard at the turn of the century, and purchased both the eastern and western portions of the vineyard in the early 1990s, (In the 1870s, under “Captain” William Litton’s ownership, the two were part of one property; spelling evolved into “Lytton” by 1903.) The vineyard is planted to zinfandel and its principal complementary varietals. 74% Zinfandel, 16% Petite Sirah, 8% Carignane, 2% Mataró (Mourvèdre)'
