Maroggia is the westernmost of the historic sub-zones of Valtellina Superiore and lies within the municipality of Berbenno di Valtellina, at altitudes ranging from 270 to 550 metres. The vineyard follows steep, terraced slopes with south-facing exposures that encourage a long ripening period for the grapes and provide plenty of sunlight. The alpine climate, tempered by breezes from Lake Como and valley winds, creates conditions that help preserve the wine’s freshness and define its aromas.
The geology is characterised by the presence of gneiss and alluvial soils rich in sand, gravel and pebbles, which are generally shallow and rest directly on the bedrock. In this environment, the vines develop a direct relationship with the mineral substrate, whilst the dry stone walls help to retain heat and shape the vineyard’s microclimate.
The main variety is Chiavennasca, the local name for Nebbiolo, alongside traditional varieties such as Pignola, Rossola and Brugnola. The wines of this sub-zone are Valtellina Superiore, characterised by great finesse, structure and tension, with subtle aromas, a balanced tannic structure and a marked potential for ageing. Viticulture, practised amongst old vines, terraced slopes and using manual labour, retains a strong Alpine character and a winemaking tradition deeply rooted in the landscape.
