The 2007 Kiamie White Kuvée is a serious wine in spite of the kitschy spelling of cuvée. A blend of 65% Viognier and 35% Rousanne, it has seen oak, but unlike many Viognier and Viognier blends, it is most definitely not a Napa Chard wannabe.
I will admit that some Napa Chards have exceeded the idea of balance in favor of the overdone ("What was that vintage? 2006 Louisville Slugger? Yum!") With that being said, I'd rather have an overoaked Chard than one that tastes like lemonade laced with pineapple juice. I want WINE, not a melted popsicle.
