L'Ecole Nº 41 has been producing premium handcrafted wines in the Walla Walla Valley since 1983. The winery, housed in the historic Frenchtown School depicted on its label, is family-owned and operated by Martin and Megan Clubb. The winery maintains its original focus on Merlot and Semillon, and produces smaller quantities of Cabernet Sauvignon, Syrah, Chardonnay and Chenin Blanc. The principal estate fruit is grown at Seven Hills Vineyard which was named by Wine & Spirits Magazine (June 2004) as "One of Ten Great Vineyards in the World."
Columbia Valley Cabernet is a blend of several premium vineyards including: Bacchus & Dionysus, Klipsun, Willard Farms, Portteus, Candy Mountain, Pepper Bridge, Seven Hills, and Milbrandt Vineyards. Most of these vines were planted in the 1970's and early 1980's resulting in an average vine age of over 25 years.
