Where does the best riesling grow?

Viognier grapes can be difficult to grow and low yielding. The variety is not very resistant to disease. Some wine critics feel that the terroir (microclimate) of the regions of France where it traditionally is grown is essential to its best expression in wine. It should neither be picked too early nor too late if wine of the highest quality is to be made. The grape prefers warmer environments and a long growing season, but can grow in cooler areas as well. It is a grape with low acidity; it is sometimes used to soften wines made predominantly with the red Syrah grape (Côte Rôtie from France or The Laughing Magpie from South Australia being two examples), and is blended with other white and red varieties, but it can make outstanding wines by itself. The color and the aroma of the wine suggest a sweet wine but Viognier wines are predominantly dry, although sweet late-harvest dessert wines have been made.
