The area includes the municipalities of Morgex and La Salle. 

The splendid vineyard landscape has the Mont Blanc chain as its background and is surrounded by pastures, steep slopes and coniferous forests. In these lands with almost prohibitive environmental conditions, viticulture is made possible, in the first place, by the presence of Prié blanc, the only native white grape variety in the Aosta Valley. Prié blanc has a very short vegetative cycle, budding late in spring and ripening early in early September. It thus manages to escape the spring frosts and avoid the first snows. 

In these places the vineyards have a low pergola training form, ranging from 50 to 130-140 centimeters from the ground. The choice of this typology has reasons linked to the strong thermal excursion between day and night; if the bunch were too high, it would run the risk of freezing at night. By being so close to the ground, however, the heat gained during the day is released, preserving the grapes. In addition, the low pergola is ideal for counteracting possible damage caused by the wind as well as making it more stable in the snow. 

Finally, it is worth remembering that Morgex-La Salle is one of the very few areas under vines where the vines are generally free of foot, that is, they are not grafted on a rootstock resistant to phylloxera, since the climatic conditions and the nature of the soil do not allow phylloxera to complete the biological cycle.
