The “Montello-Colli Asolani” DOC area expands in the north west of the city of Treviso, in the first piedmont hilly zone. 

This area is represented by a very long zone at the foot of the hill and by a very long hilly zone facing east-west direction, joined by a plain area and by the Mercato Vecchio hills of Montebelluna and of Caerano San Marco.
