Ten vitamins of the B-complex were determined by microbiological methods in four commercially prepared Swiss grape juices. The amounts found are reported and compared with those found by some previous authors in grape musts and frozen grape juices.A majority of the juices tested contained measurable amounts of the vitamin B-complex. The nicotinic acid, biotin, thiamine, inositol and pantothenic acid content of the juices compared favorably with that found previously in grape musts and frozen grape juices. The light-labile vitamins, folic acid, riboflavin, and the vitamin B6 complex as well as p-amino-benzoic acid and choline were found to be present in lesser quantities then those previously reported for grape musts and frozen grape juices.
