Di Costanzo Wines, established in 2010 by Massimo Di Costanzo and his wife Erin, is located in Napa Valley. Massimo, who transitioned from studying economics to winemaking at U.C. Davis, has extensive international experience, having worked in various wine regions including Italy and South Africa. His career in Napa began at Provenance, followed by significant roles at Ovid and Screaming Eagle, where he gained recognition. The winery sources grapes primarily from the Farella Vineyard in Coombsville, known for its older Cabernet Sauvignon vines. Massimo emphasizes minimal intervention in winemaking, focusing on producing balanced wines suitable for aging, typically aged in 50% new French oak. The winery's production has grown from 100 cases to around 1,200 annually. Erin plays a key role in sales and distribution, leveraging her background in the wine industry. The winery also produces wines from other notable vineyards, including Caldwell and Montecillo, showcasing a commitment to quality and terroir. Visitors can expect a tasting experience that reflects the couple's passion for crafting elegant, varietal wines with a focus on organic farming practices.
