The geological history of this area is very important and interesting to better understand the unique character of the wines produced in this territory.
30 million years ago the southern part of Piedmont was covered by sea . The Alps were about some hundreds of meters high above sea level and the Langhe hills were just cliffs. Because of the tectonic movements the hills were formed and a very special pattern of soil created. There are in fact in some areas compact lower layers of rocks caused by the compressed layers of clay, and in other zones more sandy soils. Most sub-soils show layers of different types and are often a mixture. Another proof that in this area there was the sea is the fact that fossils of plants, skeleton of fishes and shells have been found here.
Finally the sea withdrew from the Po valley and in the Quaternary era there were great changes in the flora and fauna. The new landscape formed and the former sea soil, clay mixture and marl , became the present ‘terroir’ of the Langhe wines.
The land of our vineyards is composed of light pale tufa , white or grey, lightly sandy , with the right percentage of clay suitable to maintain the correct humidity needed for the vines.
