2) Sterling Vineyard 1997 Napa Valley Merlot:
3) Earnest and Julio Gallo Reserve White Grenache 1991 (two bottles):
4)Augey 1995 Bordeaux:
5) Glen Ellen Proprietor's Reserve 1997 White Zinfandel:
6)Beringer 1999 White Zinfandel:
7)Beringer 1998 White Zinfandel:
8)Sutter Home 1997 White Zinfandel:
9)Martini & Rossi Asti with ABU00429073 imprinted on a pink sticker marked with DOCG:
