Vintage Notes

In this second drought year, Mazzoni’s non-irrigated old vines barely made it through a hot, dry summer to ripen a small crop. We filled four open-top fermentors, and gently re-circulated to extract color and tannin. To maintain balance, we pressed after only five days. Following a quick natural malolactic, we selected the best lots; for the first time in years, zinfandel, rather than carignane, predominated. This delicious wine is approachable now, and will develop further over the next 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.
