The territory is composed of hills formed millions of years ago, with acidic porphyric soils and a surface layer of fertile topsoil.
On the western side, soils have a greater abundance of sand with marine deposits, while to the east more clay-rich zones are found.
To the south, soils become deeper, with a greater proportion of silt and clay compared to the other zones of the appellation.
The proximity of Monte Rosa provides a natural barrier against mountain winds and guarantees a favourable microclimate for vine cultivation.
The production zone for the grapes encompasses the vineyards found in the communes situated north of the Strada statale 142 Biellese. (via Wikipedia · CC BY-SA 4.0)
Human factors
The name Bramaterra spread among certain producers and operators resident in the communes of Masserano, Brusnengo, Curino, Roasio, Villa del Bosco, Sostegno, and Lozzolo as early as 1914.
The use of the name Bramaterra appears for the first time in a parchment document of 1447, and prior to the recognition of the DOC the wine was also known as 'vino di Masserano' or 'vino dei Canonici'. (via Wikipedia · CC BY-SA 4.0)
