Coste&Fossati is a collection of antique Dolcetto biotypes grouped by Aldo Vajra between 1979 and 1985. Cuttings were grafted in two of the estate best Barolo vineyards, Coste di Vergne and Fossati. These plants with a 'red stalk' create a limited production of the most intense and noble Dolcetto. This is a reservoir as it cannot be found elsewhere in modern days.
