Neretto

A grape referenced as a distinct blending variety in Canavese DOC's binding ampelographic base (disciplinare Art. 2, alongside Nebbiolo, Barbera, Uva Rara, Bonarda, and Freisa) for the Canavese rosso/rosato typology. Its exact ampelographic identity is unresolved from available sources: Wikipedia's "Neretto" entry redirects to Croatina, treating the name as a folk synonym used in some regions, but Canavese's own disciplinare lists Croatina separately (only in its descriptive, non-binding zone-character text, not in Art. 2) alongside Neretto — implying the two are treated as distinct grapes in this specific legal context. "Neretto" ("the little black one") is a generic descriptive name applied to more than one dark Italian grape depending on locality, similar to how "Bonarda" and "Malvasia" cover several genetically distinct varieties. Flagged here rather than resolved, to avoid asserting an identity the sources don't support.
