To the right of the Tanaro, the Langa has shaped the hills with a solid structure, a profound terrain compact in its marly trestle, grey in certain places, bluish elsewhere. At the left of the river the marly components let the layers of sand prevail which often englobe fossil shells making the soil softer and welcoming. The differences of the soil orient and guide the characters of the wines; those born on the right of the river are full, savory and long-lived; harmonic, delicate and fragrant are the ones born to the left of the river. Thus, under the same sky, both territories benefit of a cold and mild climate...today with the sun, tomorrow between the clouds, this is what helps the wines to resist time.

If the hills tell the characters of Langa and Roero today, millions of years ago there was the Po sea which covered everything. Then the tertiary era came and the sea withdrew itself bit by bit. Langa began to emerge, during the Miocene period, about 15 million years ago. After 10-12 million years, it was Roero's turn, in the Pliocene period. Today, the water has remained in the tortuous riverbed of the river Tanaro, holding to his right hand the Langa and the Roero to his left hand. On both banks the great differences reign dictated by the ancient origin of both territories and are punctually reflected in the characters of the wines produced on these hills.
