To fully appreciate the history and craft behind some of the world’s most celebrated wines - those made in Piedmont’s Monferrato - you need to head underground.  The Unesco-inscribed area, which also includes Langhe and Roero, is mostly associated with  vineyard-dotted gentle hills and picturesque villages. 

However, many do not know that, right under those hills, there are spectacular cellars where wines are left to age; some are centuries-old, and their origins remain shrouded in mystery.
