Deficit irrigation and leaf removal modulate anthocyanin and proanthocyanidin repartitioning of <scp>Cabernet Sauvignon</scp> (<scp><i>Vitis vinifera</i> L.</scp>) grape and resulting wine profile

Abstract

The DILR was the most favorable for the repartitioning of anthocyanin and PA metabolites, and promoted the accumulation of tri-substituted forms contributing a higher color intensity, mouthfeel persistence, structure, and astringency of wine. This information provides an important strategy for modulating the anthocyanin and PA compositions by agricultural practices and achieving the desired quality of grapes and wines in monsoonal climates. © 2021 Society of Chemical Industry.
