The flagship variety of The Stone Ranch and Alexander Valley. We grow mostly Clone 7 on Schwarzmann rootstock. The ancient gravel beds produce ideal soil conditions limiting yields to 2-5 tons per acre resulting in significantly concentrated flavors.

20 acres of old vine head trained, spur pruned Zinfandel in our east side blocks produce flavorful grapes year after year. The blocks were planted in 1965 and 1980. In 2024 we will replace some of the older vines with clone 41 Zinfandel on St. George rootstock.

Our Petite Sirah is our sleeper variety, we sell it for blending with other varieties to give them structure and color. A highly underrated variety that thrives in our tough soil conditions.

5 acres planted to a new 6 wire sprawl trellis system that emphasizes the power of photosynthesis to bring out the ripeness and tropical fruit flavors.

One of our higher elevation blocks, 5 acres of Cabernet Franc planted in 2020 on 1103P rootstock. The roots push through 2.5 feet of gravelly loam into a layer of clay. The large canopies produced by the vigor of 1103P spread out nicely on our 6 wire sprawl trellis system. Often above the frost line and fog line, this block experiences early bud break and extended hangtime deep into autumn.

Planted in 2023, these 0.6 and 0.3 acre blocks will provide fruit for our family wine label, Lampson Family Wines. The first vintage will be in 2025.
