($11, Vineyard Brands): The Porcupine Ridge label from Boekenhoutskloof, a consistently good South African producer, is a reliable source of inexpensive wines.  This tightly-wound Sauvignon Blanc has a distinctly grassy nose and more flavor in the mid-palate than most comparably priced wines made from this grape.  The acid bite in the finish makes it refreshing. 86 Michael Apstein Aug 12, 2008
