14.7% Alcohol by Volume


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 Mazzonis 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 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 to zinfandel.

All Mazzoni Home Ranch grapes, hand harvested; destemmed and crushed; fermented on the native yeasts, followed by full malolactic on the naturally-occurring bacteria; 3.2% water addition (added to two particularly ripe parcels); 0.33 g/L calcium carbonate (to moderate unusually high natural acidity) minimum effective sulfur for this wine (35 ppm at crush; 91 ppm over the course of aging), 9 fresh egg whites per barrel (to soften tannins); oak from barrel aging; pad filtered at bottling. In keeping with our philosophy of minimal intervention, this is the sum of our actions.

Winemaker Tasting Notes

Aromas of plum, chutney, wintergreen, and cherry jam. On entry there are intense flavors of sweet tart red cherry and fresh mint. Youthful with juicy acid and chalky tannins in a long finish.

RIDGE Mazzoni Home Ranch Sonoma County 2000 47% Zinfandel; 47% Carignane; 6% Petite Sirah. Hard to tag in terms of specific fruit and pushed along by loads of caramel and buttered rum sweetness, this ripe, oak-drenched red wine veers well wide of Zinfandel fruitiness and crashes into both abrasive tannins and flaring heat at the finish. SCORE: 83

California's 1997 Zinfandels

Ridge’s 1997s are among the highlights of this vintage. The opaque ruby/purple 1997 Mazzoni Home Ranch Proprietary Red Wine (60% Zinfandel, 35% Carignan, and 5% Petite Sirah that achieved 13.8% alcohol) offers a beautiful black raspberry-scented nose with notes of licorice and spicy oak. It is a medium to full-bodied, smoothly textured, hedonistic wine that will provide luscious drinking over the next 5-6 years. It is an ATP selection.
