Vintage Notes

The San Lorenzo vineyard is located just north of Healdsburg. The grapes that make up this wine come from the oldest part of a vineyard planted in the 1890s. This classic field blend, based on zinfandel, includes a significant proportion of petite sirah and alicante. These deeply-colored, more tannic varieties add structure to the zinfandel fruit. After fifteen months in barrel, tannins have softened. Enjoyable upon release, it will evolve over the next ten years. JO (2/22)


Pete Seghesio owns this historic San Lorenzo Vineyard. Seghesio inherited the ranch from his mother, Rachel Ann Passalacqua Seghesio. The vineyard has been part of the Passalacqua family heritage since 1896, a few years after it was planted. Pete’s great-grandfather was a cook in the California gold fields and paid 10 gold coins for the land.

Hand-harvested grapes fermented on the native yeasts, followed by full malolactic on the naturally occurring malolactic bacteria; tartaric acid; minimum effective sulfur for this wine (35 ppm at crush, 72 ppm over the course of aging); pad filtered at bottling. In keeping with our philosophy of minimal intervention, this is the sum of our actions.
