Thorevilos

Abreu Vineyards is a boutique Napa Valley producer founded in the 1980s by third-generation farmer David Abreu. It focuses on four estate vineyards—Madrona Ranch, Cappella, Las Posadas, and Thorevilos—farmed with meticulous, terroir-driven practices. Annual production is minimal, around 12,000 bottles (1,000 cases), from roughly 70 acres. Winemaking, led by Brad Grimes, emphasizes co-fermentation and careful blending of single-vineyard Cabernet lots. The property on Howell Mountain, acquired in 2000, preserves historic redwood stakes and sits above the fog line amid protected forest. While no formal sustainability certifications are noted, the winery demonstrates a deep commitment to land stewardship, craftsmanship, and uncompromising quality, declassifying vintages that do not meet its standards.
