All Ceritas wines, including the Ceritas Porter-Bass Vineyard Chardonnay Sonoma Coast 2015, are not available at retail stores,  You can only find them in small quantities at the best restaurants or directly from the winery.  

Perched like a saddle between ridgelines in Pocket Canyon, the Ceritas Porter-Bass Vineyard Chardonnay is grown on a site that is the beneficiary of cooling morning and afternoon fog, which rolls in reliably from the ocean. Shale and fractured sandstone soils are well suited to the Chardonnay planted in 1980 to the Old Wente Clone, followed in 2001 by Pinot Noir plantings of Swan and Calera clones. The vineyard is farmed biodynamically, with our blocks located on the north facing side, allowing for an extended growing season.
