The nature of the rocks and the stratification of the soil directly influence the behaviour of the plants, since they have an influence on the absorption of water and mineral elements. The grapevine is one of the most delicate plants and suffers from the change of such pedoclimatic conditions and, even though it has a certain sturdiness that enables it to adapt to a wide range of soils, it physiologically responds in different ways to variations, even if limited. This particular response ensures that every vinery and therefore every wine that originates from it, represents a unity that cannot be separated from the territory from which it generates, becoming a unique and irreproducible natural patrimony. In ancient times (35-55 million years ago), the Friulian plain was submersed under the sea and the costs were situated just before the current Julian Pre-Alps. Deep under this archaic lagoon, during the millennia, there was a slow sedimentation process that originated majestic formations that, when the sea retreated, emerged from the water. These soils constitute the hills of the Colli Orientali and of the Collio, that is of the flysch that formed for sedimentation and subsequent compaction of the clastic sediments consisting of alternating layers of variable thickness of marl (calcareous clay) and sandstone (calcified sands) that grant the abundance in minerals and trace elements and soil texture conditions that are perfect for high quality grapes. Locally, this kind of soil is called Ponka .
