White Northern Rhône
If you don't know the wines of Condrieu, and given the tiny volumes produced, that is likely to be the case, you owe it to yourself to find out what Viognier tastes like from its homelend here. These wines have that peachy, blossomy, occasionally lychee fruit that is so distinctive, and they also have the freshness and acidity, the herbal nuance and grace which is so often absent in Viogniers grown elsewhere. Don't take too much notice of advice to drink right away either - many of these wines benefit from a year or three in the cellar.
It's also worth taking a look at the two white Saint Josephs which are excellent examples of what good growers and winemakers can achieve with Marsanne and Roussanne.
