Abreu Vineyards. Founder, David Abreu (3rd generation Napa Valley) grew up working among vineyards. After graduating from the University of California Davis with a degree in Viticulture and Enology, David founded David Abreu Vineyard Management, Inc. in 1980 and that same year also developed the Madrona Ranch Vineyard in St. Helena. The first commercial vintage of an Abreu wine was the 1987 Abreu Madrona Ranch.From a viticulture perspective, Abreu has played an instrumental role in improving the quality of wines in the Napa Valley, raising the bar to another level beginning in the 1990s. He is highly selective of vineyards sites he works with; his resume in the Napa Valley is impressive, working with the likes of Screaming Eagle, Staglin Family Vineyard, Colgin Cellars, Harlan Estate, Bryant Family Vineyard, Araujo Estate (now Eisele Vineyard) and Grace Family Vineyards.Fruit for the Abreu wines comes from four spectacular up-valley vineyard sites – two in St. Helena on the valley floor both within less then a mile from each other including Madrona Ranch and Cappella, and two hillside vineyards – Thorevilos Vineyard (just below Howell Mountain) and Las Posadas Howell Mountain. David was the vineyard architect, is the vineyard manager and oversaw the planing of the vines for these four sites.Madrona Ranch is located near the eastern edge of the Mayacamas mountains in St. Helena on an alluvial fan that has spread out from the nearby Mayacamas mountains. This vineyard is very close to Spottswoode Winery and on both sides of the lower part of the driveway that leads up to Newton Vineyard. This is the first vineyard in the Abreu portfolio and was developed by David in the early 1980s.
