For over a century, the Seghesio family has played an integral role in the evolution of the region's viticulture. The winery was established in 1895, when Italian immigrant Edoardo Seghesio planted his first Zinfandel vines in what is now Seghesio’s ‘Home Ranch’ vineyard in Alexander Valley. Edoardo and his wife Angela continued growing vines during the Prohibition years, and were the only winery in the region to survive that era. Seghesio’s reputation for world class Zinfandel was cemented under the guidance of third generation Pete Seghesio and his cousin Ted Seghesio in the 1980s. Italian consultant winemaker Alberto Antonini's influence can be seen in the juicy, approachable style of Zinfandel that has become Seghesio's hallmark. Seghesio owns 120 hectares of sustainably-farmed vineyards across several renowned appellations in Sonoma, including Dry Creek Valley, Alexander Valley and Russian River Valley.
The 2018 growing season began with slightly lower than average rainfall, however timely showers in February and March meant that the soils were near saturation during budbreak. May and June were warm, which led to prolific growth in the vines and a slightly above average crop level on the vines. Harvest was unseasonably cool, lacking the heat spells that are typical of early September in Sonoma County. This allowed for a slower, methodical harvest, and the grapes retained higher acidity and lower brix, which was ideal for Zinfandel. Favourable weather conditions extended the harvest through to late October, allowing for increased flavour development and concentration.
