($17, Winebow): Daryl Groom knows a thing or two about winemaking, having made wine in California for two decades.  He’s probably best known for being the winemaker at Penfolds in Australia responsible for their iconic Grange in the mid 1980s.  But he also was Penfolds’ chief white winemaker, which probably explains why this Sauvignon Blanc is so good.  It has stylish grapefruit pungency without being overdone.  Zesty, but without screaming acidity, it has body and conveys refreshing citrus flavors.  This is a terrific example of Sauvignon Blanc—and it’s under 13% alcohol.  Buy it. 92 Michael Apstein May 18, 2010
