The Perego family has been tending vines on these sheer granite terraces in the mountainous Valtellina since 1860. The vines are so far north into the alps they are practically in Switzerland. They work only with Nebbiolo, growing the grapes up to 700 metres above sea level on sheer, south-facing, sunlit vines that dig straight into rock. The resulting fruit is intensely mineral. Everything in the vineyard is done by hand, leaving the wines to rest until they are deemed ready for release.
