Ruché is clearly distinguished from the other Piedmontese varieties by the characteristic and original wine derived from it. The only regional product it resembles is Brachetto, although there are considerable differences from an ampelographical standpoint. It does best in calcareous soils that are dry and well exposed. Such conditions are typical of the restricted zone of Castagnole Monferrato and the variety is not cultivated in any other production zone. Annual output of Ruché wine, which in the past was almost entirely consumed by local families, is still modest although steadily expanding. That growth has been spurred by the wine’s recent DOC recognition.
