Terroir: The morphology of the production area of ​​the Colli Trevigiani IGT consists of a series of hilly ridges arranged in a north-south direction in the southernmost part and with an east-west direction in the northern part. These reliefs are separated by a series of valleys crossed by small watercourses. The area to the north rests on the pre-alpine chain that acts as a natural barrier at the entrance of cold currents, while to the south the area enjoys the mild temperatures of the Venice lagoon, from which it is only 40 km. The east-west layout of the hilly terrain, the steep slope, the consequent position facing south of the vineyards, allows maximum interception of the sun’s rays, creating an ideal area for the cultivation of the vine. The soils of the area originated from the raising of seabed and were subsequently modified by the action of the glaciers and rivers. The terrain consists mainly of sandstone and marl, alternating with moraine and alluvial layers. This profile favors the constant drainage of water.

Climate: Temperate, with well-defined seasons, marked day-night temperature excursions during the grape ripening due to the descent along the slopes of the hills, fresh air coming from the Pre-Alps. The frequent rains of the summer guarantee the water supply sufficient for the optimal ripening of the grapes. This particular condition is realized thanks to the strong acclivity and the scarce depth of soil that can be explored from the roots of the vines.
