Riesling

Riesling is one of those underrated grapes, and often remains so, despite the advocacy by wine merchants and wine writers. Its original home is Germany, and Alsace, but it has since found more global favour in Australia, the US and even Chile. It can generally be a bit lower in alcohol, lip smacking natural acidity, and like Chardonnay, can be a great chameleon grape, taking on aspects of where it's grown. Even better, because of years of under-appreciation, it can be amazing value.
