When he first settled in Napa Valley, Louis M. Martini sought to source from the most coveted vineyards in the region. With the 1938 purchase of the Goldstein Ranch in the Mayacamas Mountains, he embarked on a new chapter in advanced viticulture and vineyard-driven winemaking. The vineyard, renamed Monte Rosso for its red volcanic soils, has since become the emblematic source of some of our most sought-after releases. Today, we continue to source the best grapes possible from Napa Valley and beyond.
The Monte Rosso Vineyard is perched in the Mayacamas Mountains, a thousand feet above the Sonoma Valley. Named for its iron-rich, red volcanic soils, Monte Rosso has produced grapes of unmistakable character for more than a century. Three generations of Martinis have made wine from this iconic vineyard and it remains the source of some of the most coveted bottles in our portfolio.
Stagecoach Vineyard is planted to 600 acres of vines on ancient volcanic terrain in the rugged Vaca Mountains. It is the largest contiguous vineyard in Napa Valley and revered for its powerful, complex fruit and bold tannins.
Our Cypress Ranch Vineyard basks in the warmth of Pope Valley, where long, warm days and cool, crisp nights dictate one of the largest diurnal shifts in all of Napa Valley. Cypress Ranch yields Cabernet Sauvignon with a unique boysenberry quality, a distinct balance between black and red fruit. The wines are also graced by an elegant complexity and soft, dusty tannins.
Sun Lake Vineyard sits next to Cypress Ranch on the flanks of Howell Mountain, yielding intricately layered Cabernet Sauvignon in the warm climate and well-drained, rocky soils of Pope Valley.
The 10-acre Thomann Station Vineyard sits behind the winery in the vast warmth of the Napa Valley floor in St. Helena. This backyard vineyard – named for the Southern Pacific Railroad fruit packing stop that once called this land home – has deep gravelly loam soils. Ideal for growing Petite Sirah, Thomann Station was planted entirely to this variety in 1996. It was here that Louis P. Martini first introduced wind machines in 1951 to combat frost in the vineyard.
