THE TERRITORY OF TREISO

A precious pearl set in the lower Langa and immersed in the most famous vineyards in the world

A road uphill, among the vineyards of Nebbiolo, Barbaresco and Dolcetto, in the most genuine and natural Langa, in the heart of the Barbaresco area, is the path that leads to Treiso, a UNESCO site 410 meters above sea level and about 9 km from Alba, 5 km from Barbaresco and another 5 km from Neive.

Treiso  is a small village, a "segment" of the Langa, with the Church and the bell tower in the center of a square (one of the largest in all the Langhe), around which group and develop houses scattered throughout the surrounding territory.

At Treiso there is a view  that strikes straight to the heart, a sort of terrace on a wonderful panorama made of vineyards and hills that change color with the seasons.

“From that small square you can overlook a little Langa on the left and right the hills of the Oltretanaro after which there is the plain at the end of which is the great city of Turin. The morning vapors slowly rose and the hills appeared as if they were being taken off a dress from below up.

Negus said, as if among himself: - This world is made to live in peace with us”.

Beppe Fenoglio, The outward journey

The name Treiso is inextricably linked to that of Barbaresco.

Tresio is located in the heart of the Barbaresco area, exactly at the meeting point of 5 hills.

The structure of the territory is formed by a conspicuous frame of long hills, alternated by deep and medium wide valleys. The gullies are frequent, an extremely fascinating effect of the erosive phenomenon of water. The Barbaresco area is not fundamentally different from the Barolo area from a geological point of view.

The whole Barbaresco area is of Miocene origin (that is, it belongs to the Tertiary or Cenozoic Era) and of marine formation, with the exception of alluvial areas of Holocene origin (Quaternary or Neo-Nozoic Era). The soil is mainly made up of calcareous marl, sedimentary deposits that climbed to the surface with the gradual lifting of the primordial sea bed that covered the Po basin. Although the Barbaresco area is homogeneous, it can be divided into two parts according to the prevailing soil types:

·       The soils of Treiso, San Rocco Seno d'Elvio and Neive, south of the town centre, belong to the " Formations of Lequio " (Tortoniano-Serravalliano), characterised by layers of compact grey marl alternating with layers of sand.

·       The land of Barbaresco and the part of Neive that is leaning against Barbaresco belong to the " Marne of Sant'Agata Fossili " (Tortoniano), characterized by calcareous bluish marls.

Another important element, primary to define the quality and character of a grape like Nebbiolo, so difficult to ripen completely, with its need to get the maximum amount of heat and sunlight, is altitude.

The altitude above sea level is between 150-450 meters, which is practically the ideal range for growing vines at these latitudes.

But at this point a clarification is required: the automatic identification between low levels and higher heat must be avoided, since exposure, slope position, presence or absence of wind currents and landscape configuration are also of fundamental importance in determining a precise microclimate. It is interesting to note, however, that the nine locations referred to as "chosen positions" by Fantini at the end of the 19th century – New Farmhouse, Burnt Farmhouse, Casotto, Ghiga, Rivosordo, Roncagliette, Manzola, Frattino, Valeirano - all belong to a fairly narrow range of elevation values. Their altitudes in meters above sea level are: 278, 321, 316, 210, 260, 334, 219, 260 respectively. Nevertheless, without letting us go to easy generalizations, the ideal altitude range for the Barbaresco seems to be between 200 and 350 meters.
