Part of the current company's vineyards can be traced back to the winery Eshcol, a biblical word for “lush cluster of grapes.” The original Eschol winery was commissioned by James and George Goodman and constructed in 1886 by a Scottish sea captain named Hamden McIntyre.

The vineyards survived Prohibition in the United States by producing grapes for the production of sacramental wine.

At that time, replanting of the vineyards and restoration of the historic winery building began.

The 1976 Trefethen Vineyards Chardonnay won first place in that category and was judged best in the world.
