Our 10-acre Thomann Station Vineyard sits behind the winery in the vast warmth of the Napa Valley floor, as it has since the days of Louis M. Martini. Our 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 varietal in 1996. It is here at Thomann Station that Louis P. Martini was among the first to introduce wind machines in 1951 to combat frost in the vineyard. Today, we craft our small lot Petite Sirah from the grapes grown at this Napa Valley vineyard.
Considered the jewel in the crown of Louis M. Martini Winery, our Monte Rosso Vineyard is among the most highly regarded grape growing sites in California. Nestled on the southwest slopes of the Mayacamas Mountains, near the town of Agua Caliente, the property cultivates complex and intense Cabernet Sauvignon and Zinfandel. Originally planted in 1880, the vineyard fell victim to phylloxera and was replanted in 1890 with Zinfandel vines that persist in meandering up the slopes today. Louis M. Martini purchased the property in 1938 and renamed it "Monte Rosso" for its mountaintop setting and bright red, volcanic soils. His original plantings of Cabernet Sauvignon from that same year produce fruit for our family's wines to this day.
With rich gravelly loam soils washed down from the surrounding hills in the heart of Chiles Valley, the Ghost Pines Vineyard produces intensely flavored Cabernet Sauvignon and Merlot grapes. Nestled 12 miles east of St. Helena in the eastern hills of Napa Valley, the Chiles Valley appellation has a natural wind tunnel that cools the valley floor. Ghost Pines Vineyard rests 700 feet above sea level, where warm summer days prevail. The hot, dry air is tempered by cooling fog in the mornings and evenings, giving Merlot and Cabernet grapes the ideal conditions for developing pronounced, well-structured fruit flavors.
Tucked away in Napa Valley's most remote grape growing region, under the palisades of Howell Mountain, Sun Lake Vineyard enjoys abundant sunshine year-round. A former walnut orchard in the Pope Valley sub-AVA, Sun Lake was planted to wine grapes in 2003 using an advanced trellising system that optimizes sun exposure on the Cabernet Sauvignon vines. Resting 800 to 1,000 feet above the Napa Valley floor, the vineyard is protected from the morning fog most of the year, resulting in greater extremes in temperature. Limited water encourages the vines to produce smaller berries and clusters, giving the wine more intense aromas and flavors. Cold nights temper the abundant sunshine, affording the grapes a lengthy growing season with plenty of time to develop incredible flavor characteristics for our Cabernet Sauvignon wines.
