The Rhone vineyard is a world apart; terraces in steep sides, playing leapfrog with the green hills. However, it is hard to speak of one whole Rhone vineyard, as the valley diversifies itself along the river. For the northern coasts - which range from Vienna to Valence on granite slopes - main grape varieties are Syrah for red wines and Viognier for white wines, as well as Roussanne and Marsanne.
As for the southern coasts - ranging from Montélimar to Avignon; the vine takes up all the space on limestone soils, originating lots of grape varieties. Grenache is the main grape for red wines; whilst for whites they are Clairette and Bourboulenc.
The diversity of influences, both geological and climatic, can only favour a very varied wine production. Birth and development of viticulture in the region also owes much to history, notably with the implantation of the papacy in Avignon at the end of the Middle Ages.
Rhone Valley red wines have colours of varying intensity, ranging from ruby to very dark purple, and even black in their youth. The best ones have depth, persistency in mouth and harmony; they can surely compare to the great wines of Bordeaux. Most famous red wines are Côte-Rôtie, Crozes-Hermitage and Châteauneuf-du-Pape; for what regards white wines, Condrieu and Clairette de Die are the most celebrated appellations. At the south of Cornas, Saint Péray is renowned for its sparkling and full-bodied sparkling wine, while in the Drôme area, Clairette de Die is light and aromatic.
