What grows here
Castelletto Merli
17 protected denominations overlap in this municipality.
Set within the Alessandria hills of Piedmont, the quiet enclave of Castelletto Merli—home to fewer than 450 residents—nurtures 17 protected denominations. Foremost among its viticultural treasures is Grignolino del Monferrato Casalese DOC, an ancestral red wine shared with a select group of only 34 municipalities. This tight-knit terroir is kept alive by 1 verified estate based directly in the village, which is also open for tastings and cellar visits, offering travelers an intimate encounter with the hillsides that feed both this rare vintage and the wider-reaching Barbera d'Asti DOCG.
