In 1968 a walnut orchard in the Southwestern corner of Napa Valley, in what is now the AVA of the Oak Knoll District, was converted to Cabernet Sauvignon vineyards by Bruce Newlan, a rocket scientist from San Jose who vacationed in Napa Valley. The roots of Silenus Winery were firmly established.
The choice of locating in the Oak Knoll District (OKD) was very deliberate. The OKD lies at the southern end of the Napa Valley where the growing season is longer, providing early bud break and a long, leisurely growing season for optimal, balanced ripeness.
