“Alta Langa” is defined as the highest part of the hills in Langhe, in Piemonte, with a height of over 350 masl. In the areas of Vesime, Bubbio and Cassinasco the soils lose the special composition alchemy (marl), making them unsuitable for the cultivation of vineyards in Nebbiolo. In these mixed, calcareous-clayey soils, other grapes are grown with good results.
