Anthocyanins and flavonols berries from Vitis vinifera L. cv. Brancellao separately collected from two different positions within the cluster

► Differences in flavonoids were observed in Brancellao berries of shoulders and tips. ► Accumulation of anthocyanins in skins was higher in the shoulders than in the tips. ► Flavonol content in flesh was highest in the tips. ► Blockage of phloem elements in the berry can explain the different influx of solutes. ► At harvest, contents of anthocyanins and flavonols were similar at both positions.
