Vibrant and refreshing, this is the most transparent wine we make, a pure expression of our estate vineyards. We produced our first Riesling in 1974, made in a distinctively dry and crisp style. It has been a family favorite ever since. Bright and aromatic, it is marvelously food-friendly and cellar-worthy.

The future of our winery is in our vineyards. The family’s future is in the third generation of Trefethens, for whom this wine is named—Hailey and Lorenzo. HāLo is sourced entirely from our Hillspring Vineyard, where shallow, rocky soils, coupled with a climate protected from fog and wind, allow us to grow truly exceptional Cabernet Sauvignon.

Our Nana, Catherine Trefethen, was Welsh. Her twin loves of wine and family were the original inspiration for our estate in Napa Valley’s Oak Knoll District. Celebrating our heritage, “Y Ddraig Goch”, the symbol of Wales, adorns this bottle of Dragon’s Tooth, a provocative blend born from the rockiest part of our vineyard.
