Paul Dolan Vineyards Zinfandel is sourced from two unique vineyard sites in the heart of Mendocino County – La Ribera Vineyard and Chase Vineyard. Located along the banks of the Russian River, La Ribera Vineyard sees long warm days and cool nights during the growing season, resulting in bright aromatic fruit with balanced acidity. Located in the eastern hills of the Redwood Valley, the Chase Vineyard has a cooler climate than surrounding appellations, which leads to the gradual ripening of the fruit and results in refined, complex wines.
