The territory of the DOC Piave is enclosed by a vast plain that stretches from the borders of the northeastern province of Treviso with Friuli, to the mouth of the Piave, in Cortellazzo (VE); from the hills of Conegliano and Montello to the first inland of the city of Venice. This large area (which represents one of the largest Doc in northern Italy) presents a great variety of soils and microclimates, which can produce wines very different from each other, due to the several different types of vines.
Starting in the north and going down south, the soils are related to the force with which the Piave carries the materials collected on the hills and in the mountains. From ancient red soils corresponding to the first presence of the Piave west of the Montello, to the soils rich in texture, to those of medium texture, and finally to the soils mainly made of clay. The soils are considered "hot", as they are characterized by a high percentage of texture, with high depths which can be explored by the roots, absence of stagnation, poor in organic matter, with good and well balanced mineral elements, in particular phosphorus and magnesium.
A diversified pedology combines with minimum and maximum temperatures of sharp gradients, temperature ranges that reach the highest values in the northeastern part of the Doc, warmer temperatures below the Motta-Oderzo line, and precipitations varying from one area to another. The zoning begun in 2007 allows each pedoclimatic and geologic environment, and then, each vine thereby contained, to express themselves better through the indications derived from the significant findings on the soils, plants and fruits.
