Jon Ruel

About:

Since his arrival at Trefethen in 2004, Jon has played a key role in furthering our mission of making world-class wines that fully capture our estate vineyard’s unique terroir. Hired initially as our viticulturist, Jon quickly made small changes that had huge, beneficial effects on wine quality. Taking a horticultural approach to grape-growing, he insists that each sub-block, row and vine in our vineyard receives the attention it needs when it needs it, keeping our vineyard crew constantly on the move. With an approach blending ancient methods with modern technology, Jon now guides the entire process of crafting our wines from vineyard to bottle. He does so with a keen environmental awareness derived from his scientific background, which includes an M.S. degree in Viticulture and Enology from the University of California at Davis, an M.S. degree in Ecology, and over 10 years of ecological research spanning the globe from Antarctica to the Norwegian Arctic.

Jon served as President of the Board of Directors of the Napa Valley Grapegrowers and as a member of the advisory council of the Bay Area Air Quality Management District, a regional agency entrusted with regulating air quality across all nine counties of the San Francisco Bay Area. He speaks frequently at wine industry events, where he often details Trefethen’s extensive sustainability programs, including La Huerta, the five-acre fruit and vegetable garden Jon created on our estate to provide free, delicious produce to our employees.
