Washington State has become internationally recognized as having some of the world's best conditions for growing superb wine grapes and as a breeding ground for an ever-growing number of innovative winemakers. Many of these came out of the local wine trade with little capital but an intimate knowledge of wine and wine regions.
O·S Winery started life as a partnership between Rob Sullivan and Owen with one thing in mind: producing irresistible, jaw-dropping wines. Securing fruit from the best vineyards and working with growers on the details of viticulture was and remains the foundation of our endeavor. Our focus since the beginning has been on select sites and low yields combined with a winemaking ethic centered on simplicity (i.e. no fining, no filtering, gravity fed production) all with one aim: Opulent, Voluptuous, Concentrated Red Wines.
