Stacy Clark’s interest in winemaking was inspired by her biology teacher in high school, who included the science of winemaking in his course. She enrolled in UC Davis to study biology, her favorite subject at that time, but after taking introduction to winemaking, a required course, she changed her major to Fermentation Science and Enology. This led to her receiving a B.S. degree from the University of California, Davis, in Fermentation Science and Enology. Her first experience with Napa Valley fruit was with Stag’s Leap Wine Cellars while she was still a student at UC Davis.

After graduating, her first position was as an enologist at Pine Ridge Winery, which she joined in 1983. There, she rose through the ranks to become its winemaker. During her nearly 26 years at Pine Ridge, the winery grew slowly but surely from Stacy’s first harvest, when production hovered around 7,000 cases, to more than 75,000 cases of wine made from estate fruit, with Merlot, Cabernet Sauvignon, Malbec, and a new Bordeaux blend accounting for the lion’s share of the wines she crafted.

She joined Charles Krug Winery in 2011 as its winemaker. In this role, Stacy and her team work together with the Peter Mondavi, Sr., family stewarding the family’s estate vineyards located from Howell Mountain to Carneros in the Napa Valley. and crafting the premium Napa Bordeaux-style wines that this historic family is famous for making.

Stacy also founded her own brand, Galland Clark, in mid-2009, where she specialized in producing Cabernet Sauvignon under that label. The winery was closed in 2021.
