The objective of this study was to characterize the levels of mineral nutrients: N, P, K, Ca, Mg, S, Mn, Fe, Zn, Cu, Mo and B of twelve genotypes of grapevine: 'Italy', 'Ruby' , 'Patricia', 'Isabel', 'Redglobe', 'Roberta', 'Kyoho', 'Roman', 'Rosalinda', 'Moscatel de Hamburgo’,' 'Niagara Rosada' and 'UVF 01' in the North of Rio de Janeiro State. The plants were pruinned and fertilized (organic and mineral).  The leaf blades were analyzed in two periods of the reproductive cycle of the vine: in full bloom and the beginning of berry ripening (veraison). In this characterization, it was concluded that the leaves reflected the nutritional status of the vine genotypes. The genotypes did not show levels of N below normal, with most genotypes showing normal levels. Neither genotype showed below normal levels of K and P. All genotypes showed levels of Ca below the normal range for all seasons and Mg in the normal range. All genotypes showed normal levels of B.
