Jenna Davis, even while quite young, knew that she wanted a career that would allow her to engage with nature to create a product from beginning to end. Her journey to becoming a winemaker began in high school, when she met Karen Culler, who had founded her own winery in the Napa Valley. A visit to her winery convinced Jenna to become a winemaker.

She earned a B.S. degree in Food Science and Technology in 2013 at Ohio State University, where she finished with a nearly perfect GPA, 3.998/4.00. At OSU, her future in wine was foreshadowed by being Founder and President of The Wine Club there. She also engaged in research internships as an undergraduate as well as brewing beer for a Columbus microbrewery, her first experience with fermentation.

Moving to the West Coast, Jenna entered the Viticulture and Enology program at the University of California, Davis, in 2014, after completing harvest internships with Opus One in Oakville and Oakvale Winery in the Hunter Valley of Australia. It was the latter experience that turned her on to Pinot Noir, which led her to a decision to focus on crafting Pinot Noir and Chardonnay in Sonoma. She held two additional internships while in school, at DuMOL winery in the Russian River Valley and at Spottswoode Winery in St. Helena. She finished her M.S. degree in 2016.

After graduation, Jenna returned to DuMOL as its assistant winemaker. She replaced Andy Smith, the founding winemaker and owner of the winery, in 2024. As she says, "Andy has created something very special at DuMOL, and I'm thrilled to continue this incredible legacy. Being able to grow and develop under Andy's mentorship, as I step into the Winemaker role, is a dream scenario.” She plans to maintain his philosophy with respect to the wines she produces, so she’ll be crafting “highly nuanced, vineyard-focused Pinot Noirs and Cardonnays from distinctive sites in the cool-climate Green Valley of the Russian River Valley . . . No matter the specific expression, our wines are balanced with great concentration of flavor.” She goes on to say that, “Every serious producer will tell you the most critical factor of winemaking is site [of the vineyard].”
