I got a better appreciation for this wine when I tasted it alongside the 2007 Monkey Bay Marlborough Sauvignon. Both wines have the classic New Zealand qualities of green pepper, gooseberries and passion fruit, but this wine is simply more elegant, the flavors more delineated. I like the passion fruit quality of Sauvignon Blanc, and this wine has more of it than its Monkey Bay cousin.
As the label points out, the Boulder Bank wine comes from specially selected vineyards, and that probably accounts for its superior quality. The Monkey Bay is on special for $9.99 at many stores right now; the Boulder Bank can be purchased for the same price at Cost Plus World Market.
