Groth produces Cabernet Sauvignon and Bordeaux blends from Oakville, the heart of Napa Valley's most prestigious red wine territory. The Cabernet Sauvignon Premiere Napa Valley X Lot No 166 and Oakcross Proprietary Red—a blend of Merlot, Petit Verdot, and Cabernet Sauvignon—anchor the portfolio. These wines have been assessed by Wine Advocate, Wine Enthusiast, Wine Spectator, Decanter, and Falstaff. Oakville's gravelly benchland soils and diurnal temperature swings favor the concentration and structure that define the region's Cabernets. The winery's core Cabernet Sauvignon rounds out a focused range built on the varietal's natural affinity for the terroir.
