Louis M. Martini is a historic and highly regarded brand of California wine, with a legacy that dates back to the early 20th century. The winery was founded by its namesake in 1933, following the repeal of Prohibition, and it quickly established itself as a pioneer in the Napa Valley. The brand's identity is deeply rooted in its long-standing commitment to crafting world-class Cabernet Sauvignon.

The brand’s philosophy centers on the belief that great wines are made in the vineyard. Louis M. Martini was among the first to explore and champion the diverse terroirs of Napa Valley, seeking out the best locations for growing Cabernet Sauvignon. This dedication to vineyard-driven winemaking has been a hallmark of the brand for generations.

Louis M. Martini wines are celebrated for their power, structure, and ability to age. While Cabernet Sauvignon remains the brand's flagship, its portfolio also includes other Bordeaux varietals and a range of wines that showcase the distinct character of California's most prestigious vineyards. The brand is considered a cornerstone of American winemaking history, revered for its consistent quality and its role in helping to establish Napa Valley's global reputation.
