Groth Vineyards & Winery is a 140-acre estate in Napa Valley. It was founded in 1982 by Dennis and Judy Groth. Dennis had been a partner at Arthur Young & Co. and later a top executive at Atari, but he and Judy decided to move their family to Napa and realize their dream of becoming vintners. They bought an estate in the heart of the Oakville appellation and hired Nils Venge as winemaker. Michael Weiss became winemaker in 1994. The estate producers Chardonnay and Sauvignon Blanc, but the star is the Cabernet Sauvignon Napa Valley Reserve, which generally earns compliments from reviewers. Wine Spectator called the 2005 a wine with “wonderful richness, density and focus, with tiers of smoky plum, currant, blackberry, loamy earth, sage and underbrush notes. Though firmly tannic, there's a measure of finesse and polish.”
