Not only Côte-Rôtie but there were many outstanding vineyards that were cultivated by E. Guigal in Rhône also. Two main regions of wine came from north and south of Rhône.
North Rhône: Côte-Rôtie, Condrieu, Chāteau-Grillet, Saint-Joseph, Cornas, and Saint-Péray
South Rhône: Hermitage and Crozes-Hermitage
The average age of the vine is 35 years.
