In 1938, Beaulieu Vineyards founder and owner Georges de Latour visited France in search of a new winemaker who had a cosmopolitan and scientific background. He was introduced to Tchelistcheff at the French National Agronomy Institute where Andre was working, along with research he was doing at the Pasteur Institute. This introduction came through the auspices of Leon Bonnet, Emeritus Professor at University of California, Berkeley and a BV consultant. Although Tchelistcheff had already received offers from winemakers worldwide, he agreed to join Beaulieu Vineyard, and arrived in Napa Valley, California in September, 1938 as BV's vice president and chief winemaker. Tchelistcheff's impact at BV was immediate and profound: he concentrated his efforts on defining a style for high-quality California Cabernet Sauvignon, and created the "Georges de Latour Private Reserve" label. He introduced new techniques and procedures to the region, such as aging wine in small French Oak barrels. By the mid-1940s, "Private Reserve" was widely recognized as the benchmark for California Cabernet Sauvignon, and was served at all important White House functions. The shift to using small American oak barrels took place after the US entered WWII, and became an accepted tradition at BV under Tchelistcheff and his successors until 1989. Tchelistcheff provided significant contributions to the techniques of cold fermentation, vineyard frost protection, malolactic fermentation, and the development of winemaking regions in Carneros, California, Oregon and Washington. He remained vice president of Beaulieu Vineyards until his retirement in 1973. He later became consulting enologist at Jordan Vineyard & Winery beginning with its inaugural 1976 vintage. He also operated a private wine laboratory in St. Helena and consulted to Joseph Heitz, Rev. John Staten of Field Stone Winery, Mike Grgich, Joel Aiken, Jordan, Neibaum/Coppola, Buena Vista Winery, George & Peter Rubissow, Erath Winery, Sequoia Grove, Chateau Ste. Michelle, and Columbia Crest Winery. While consulting for Chateau Ste. Michelle in Washington, Tchelistcheff also gave winemaking advice to his nephew, Alex Golitzin. After four years as an amateur winemaker, and encouraged by his uncle, Golitzin founded Quilceda Creek Vintners in Snohomish, Washington, a winery that would eventually achieve six 100-point scores for its Columbia Valley AVA Cabernet Sauvignon from wine criticRobert Parker. A man of diminutive stature, his quick wit, sharp intellect, and legendarily refined palate endeared him to three generations of California winemakers, who affectionately referred to him as the "Maestro." Tchelistcheff was inducted into the Culinary Institute of America's Vintner's Hall of Fame in 2007. A grand-nephew of André, Mark Tchelistcheff, is completing a feature-length film about André: André Tchelistcheff: The voice of wine.
