Although it appears to have synonyms or morphological similarities, it must not be confused with Bonarda Piemontese, Hrvatica, Nebbiolo or Uva Rara. According to a DNA analysis carried out in 1999, there is no relationship with the Croatian variety Hrvatica, despite the same name meaning. Croatina was a crossing partner in the new breeding of Ervi. This late-maturing, high-yielding vine is resistant to powdery mildew, but sensitive to drought or drought. It produces colourful, tannin-rich red wines with fruity aromas.
