The estate lies entirely within the Monferrato area in the Province of Asti, one of Piedmont's finest wine zones. 80% of its vineyards are in the district of Portacomaro, whilst 20% are at Costigliole d'Asti. The Monferrato is quite unlike any other viticultural region: here the vineyards alternate with woodland and fields, and there is great variation in the zone's hillsides, even in the colour of their soils.
It takes its name from the medieval stronghold that dominates it, and which once belonged to the noble Bunéis family. Its northern part is today still referred to, in dialect, as the Val del Temp (which means Valley of the Temple) because the Templars had properties there, as testified by the Codex Astensis, the only authenticated record of events in Asti during the Middle Ages. The last surviving member of the Bunéis family left the estate in his will to the Bishop of Acqui who, in the 18th century, liked to spend his summers there.
Typically continental, with considerable differences between seasons and between day and night temperatures, the climate is influenced by the barrier that the Maritime Alps and the Ligurian Apennines place in the way of southwesterly winds. Relative humidity is high and snow falls quite regularly, just as summer thunderstorms are fairly frequent, too. The soils are a mixture of silt and clay, evolved on top of older formations: the Clays of Lugagnano and the Sands of Asti.
The vine training system adopted here is the Guyot espalier, the one that has always been used in all of Piedmont's viticultural zones. The property covers 174 hectares (430 acres) in all, of which 158 hectares (390 acres) are vineyards in production in Portacomaro and in the hamlet of Santa Margherita di Costigliole d'Asti.
These are aimed at establishing an equilibrium between the vines and the grapes that guarantees high quality in the wines produced. The cultivation techniques used have helped us to discover that the estate not only has a great vocation for producing red wines, but that it also has a definite aptitude for making white and sparkling wines as well.
