A True Sense of Family

  • One of Napa Valley’s pioneering wineries, Trefethen Family Vineyards crafts distinguished estate grown wines that express the unique spirit of their land, vines, and people. The dedication of the Trefethen family is manifest in every aspect of the operation, from the soil to the table, including sustainable farming, thoughtful winemaking and gracious hospitality.

    “For three generations, our family has devoted itself to wine made solely from the fruit of our estate vineyards in the Oak Knoll District of Napa Valley. A characteristic brightness animates every bottle, reflecting both our cool climate and the joy with which we approach our work.”  – The Trefethen Family

  • “To honor our legacy, we must push forward. Every vintage is an opportunity to learn something new about our land, to build on every vintage that has come before in order to better reflect this place in our wines.”


    -Hailey Trefethen & Lorenzo Trefethen

  • “The most important lesson [that we’ve learned] is that great wines are made in the vineyards, and the owners’ tracks need to be in those vineyards on a daily basis. And if they are, then that winery … will make superb wines.”


    -Janet & John Trefethen

  • “It’s important for people to understand the joy of giving and the joy of achievement … We have the responsibility of participating in those things in the community that we believe in.”


    -Gene & Katie Trefethen

Sustainable Approach


Our founders Eugene and Catherine Trefethen were ahead of their time. While terms like “sustainability” or “estate grown” were not widely used back in 1968, they understood that in order to produce world-class wines they would need a special plot of land that was treated with the utmost respect.

Today, the third generation of the Trefethen family carries on this vision. Wine lovers in search of outstanding Napa Valley wines turn to Trefethen knowing they will enjoy wines produced exclusively from our sustainably farmed estate vineyards.
