The soils of Boca are of morainic origin, derived from Monte Rosa and composed of clay, sand, granite pebbles, porphyry, and flaking fragments of dolomitic rocks from Monte Fenera.
The soils result from a superimposition of alluvial deposits of marine origin, formed when the sea covered these lands prior to the glaciation.
Air currents from the north, descending from Monte Rosa, produce strong diurnal temperature variations in the production zone.
The natural shelter provided by Monte Fenera favours mild winters, temperate springs, and warm, sunny summers and autumns in the production area.
The vineyards of the appellation are situated at elevations ranging from 300 to 550 metres above sea level. (via Wikipedia · CC BY-SA 4.0)
Human factors
The configuration of the terrain has required, from the earliest plantings, the use of horizontal terraces running parallel to the contour lines and of dry-stone walls.
The cultivation of the vine in the Boca area is considered by local farmers to be a very ancient practice, dating back to before the Roman colonisation.
