The color has lightened and lost its sheen. There is an unpleasant singed smell, like charred wood that wasn't present (or I didn't notice) a few years ago. But there are also some pleasant fruit smells and flavors. And I like the Mourvedre-spiced red berry finish.
Saint Gervais is my favorite (and the most expensive) bottling of Domaine Sainte Anne, and it generally ages well (the 2000 and the 2005 are drinking beautifully). And, if you are not into aging wine, current vinrtages of Saint Gervais are well worth the $20 to $25 price tag.
