Suisun Valley is a little known AVA only a few miles southeast of Napa Valley. Entering the valley is like stepping back in time. In this bucolic setting it is difficult to imagine that Interstate 80 is so close you can almost hear it. The valley is generally warm but it is so close to the San Pablo Bay and Carquinez Strait that is has a number of cooler microclimates. Suisun Valley can ripen almost everything—forget about Pinot Noir and Riesling, but just about anything else you can imagine does well here. Petite Sirah thrives in Suisun Valley, and will probably emerge as its signature varietal.
Everything we love about Petite Sirah is abundant in the Oberti Vineyard grapes—rich, densely concentrated flavors, intense color and tannins that are formidable but not forbidding.
