Vintage Notes

The Oltranti family has farmed this century old vineyard since 1987. Ridge started making wine from there in 1996, exclusively for the Advanced Tasting Program. The consistent quality over that time made many excellent vintages. In 2018, Ridge signed a farming lease, gaining full control over pruning, yields, and timing of harvest. This excellent growing season produced a wonderfully sensuous wine. It will be at its best in five to seven years.


Giuseppe Mazzoni and his fourteen-year-old brother-in-law, Abramo Trusendi, arrived from Italy in 1898 and went straight to work at the Italian Swiss Colony vineyard cooperative in Asti, California. In 1899, the two managed to acquire hillside acreage nearby overlooking Alexander Valley from the west. By 1910 they had built a winery and begun making wine. Except for the Prohibition years, the Mazzoni family produced wine there until 1978. They were great believers in the contribution each varietal in a field blend could make to the finished wine. Accordingly, their century-old zinfandel is interplanted with carignane, which adds elegance and lively acidity, and petite sirah, which provides spice and depth. The Mazzoni Home Ranch was purchased in 1988 by Niccolo and Flora Oltranti. They have replanted parts of the abandoned hillside, and in some years we will include a small amount from these younger zinfandel vines.

In keeping with our philosophy of minimal intervention, this is the sum of our actions.


OwenBargreen.com: 95 Points “A highly unique and impeccable blend of 56% Zinfandel, 42% Carignane and a touch of Petite Sirah, this shows beautiful balance with ripe red raspberry and red cherry flavors alongside dill and pipe tobacco undertones. Medium to full-bodied with gobs of mouth-watering acidity, this is a sensational bottling that has another fifteen years of life ahead of it.” -Owen Bargreen (August 2021)

Blue Lifestyle: 93 Points “A lovely blend of Zinfandel and Carignane grown in the Cabernet-dominated Alexander Valley, smooth and lush.” -Anthony Dias Blue (September 2021)
