Le Langhe… the name derives from the Piemontese dialect word, Langa, or tongue, referring to the ‘tongues’ of hillside which create its unique and striking beauty.
This is a plural word – one Langa, two Langhe – and indeed we can see in the map alongside an Alta (high) and Bassa (low) Langa. The Alta part overlaps considerably with the Astigiano and Monferrato and is famous, in particular, for the high quality Alta Langa DOCG sparkling wine. These are made in the classic (bottle fermented) method and use Chardonnay and Pinot Noir – so, very much in the Champagne style.
The map shows how the two correspond to each other, but there is no formal demarcation between them (though the Alta Langa appellation described above does have defined boundaries – confusing, huh?). Several appellations overlap between the two.
