Schramsberg Vineyards

Jessica’s first experience with Schramsberg Vineyards goes back to her working as the company’s lab intern in 2003. She soon joined the winemaking team full-time, as the enologist, following graduation from the University of California, Davis with a BS degree in Viticulture and Enology. Over the following three years, she was responsible for overseeing the winery’s lab trials, maintaining the company’s wine database and managing the records from each harvest. 

In 2007, Jessica moved to New Zealand and then New York, working the harvests at Cloudy Bay Vineyards and Bedell Cellars. In 2008 Jessica found herself back in California, hired at Gundlach Bundschu Winery where she quickly earned the position of associate winemaker. At Gundlach Bundschu and sister winery Bartholomew Park, she worked on the production of over a dozen different varietals and gained the in-depth knowledge of crafting quality wine from start to finish.

In 2013, she took on the role of Assistant Winemaker at Vineyard 29 in St. Helena. There she handled the day-to-day management of staff and quality control for the estate Cabernet Sauvignon, Cabernet Franc and Sauvignon Blanc programs, as well as multiple on-site custom clients’ production, under the direction of Director of Winemaking, Keith Emerson, and Consulting Winemaker, Philippe Melka.

Jessica has now rejoined our winemaking team as a seasoned veteran, and now manages wine production for the Davies Vineyards red wine program, as well as the finishing activities for Schramsberg’s sparkling wines. With the gained experience from so many quality wine producers, Jessica has the necessary skills to not only maintain, but grow the wine quality of the Davies Vineyards brand.

Jessica lives in Napa and spends her free time cooking for harvest interns, reading and tackling scenic hikes when she isn’t visiting her family in Hawaii.
