Nutritive value of different grape musts (Vitis vinifera L.).

Musts of 11 different grape sorts were analyzed for titratable acids, total sugars, nitrogen, vitamin B group (B1, B2, B6, pantothenic acid) and macro- and micro elements (K, Ca, Mg, Fe, Zn, Cu, Mn, Mo). Analyses were done on samples collected in 1983 and 1984. The nutritive value of each sample was characterised by indices based on the nutrient concentrations and recommended dietary allowances (RDA). The nutritive values of the various grape must sorts were generally similar to those of the following vintage. Favourable climatic conditions had a positive effect on the nutritive values.
