The grape variety grown in Argentina under this denomination is not the same as the one produced in other countries.
It is hardly ever used alone, although some winemakers might boast of producing an excellent varietal with it. In Argentina it is mostly used in the production of sherry or manzanilla-style wines, which in their country of origin are made with Palomino, a non-existent variety in Argentina.
