ResumoSUMMARY Investigation of the anthocyan skin pigments in hands 1, 2, and 3 isolated from Vitis vinifera var. Tinta Pinheira grapes showed that the pigments from hand 2 consisted of the 3‐mono‐glucosides of malvidin, peonidin, delphinidin, and petunidin, each acylated with p‐coumaric acid. The pigments from hand 3 consisted of the same four anthocyanins, each acylated with caffeic acid. Evidence is presented to show that the pigments in hand 1 were an artifact obtained under certain experimental conditions, and a tentative explanation for their formation is proposed.
