The owner, Ann Colgin, produces some of the best wines of Napa Valley. It is split into three sites. The legendary IX Estate Vineyard where the new cellars stand. The Tychson Hill Vineyard that was planted by Josephine Tychson in 1881. The last is the Cariad Vineyards that belong to and are cared for by David Abreu. All three sites bring forth independently wonderful Napa Wines.
