Mantonico Bianco is a native grape variety of the Ionian coast of Calabria, particularly associated with the Locride region and the areas of Bianco and Casignana. Its origins are considered ancient and are often traced back to the Greek presence in Magna Graecia; one of the earliest historical references dates back to 1601. Distinct from the Montonico Bianco found in central-Adriatic Italy, it was officially recognised in the National Register of Vine Varieties in 2014.
In the vineyard, it displays good vigour, late ripening and remarkable adaptability to hot, dry climates. The bunch is medium-sized, of medium length, conical and compact, frequently featuring numerous short wings; the berries are medium or medium-small, ellipsoidal and elongated, with a yellow-green skin that is thick, tough and rich in bloom. The leaf is generally medium-sized, pentagonal and five-lobed.
The grapes produce wines of an intense yellow colour, underpinned by pronounced acidity and a balanced structure, with fruity, citrus and sometimes floral or mineral notes. On the palate, a slight hint of tannin and a pleasant savoury quality may emerge. The good freshness promotes development in the bottle, whilst its suitability for drying allows for the production of passito wines that are golden, smooth and aromatically rich. An interesting genetic curiosity also highlights its possible kinship with Gaglioppo.
