The 'La Spia' winery originated amongst the vineyards of Valtellina, whose name is linked to the rocky ridge of the same name located in the Sassella sub-zone, a lookout and control post from the time of the Grigioni domination. In 1962, ownership of the woodland on the hill passed to the Rigamonti family, who dedicated it to cultivating Nebbiolo grapes of the Chiavennasca biotype. In 2006 the first big harvest: the "Valtellina Superiore Riserva DOCG" label was born, to be followed in 2008 by "Valtellina Superiore Riserva DOCG" and in 2010 by "Valtellina Superiore Sassella DOCG".
In recent years, La Spia has changed its production rate from just under 5,000 to over 15,000 bottles produced. The company took over small, selected vineyards in neighbouring sub-zones, such as 'Grumello' and 'Valtellina Superiore' in the town of Berbenno. From these vineyards, the increasingly careful selection of Chiavennasca (Nebbiolo) pushed the company to separate the different types of grapes.
