Climate variability and its effects in the Penedès vineyard region (NE Spain)

Undesirable compounds in wine, like OTA, biogenic amines, and pesticide residues, can negatively affect its quality and pose health risks to consumers. In addition, an excess of tannins can lead to an unpleasant rise in astringency and bitterness, which makes tannins another target of reduction.

Partial rootzone drying (PRD) is an irrigation management technique designed to reduce water use in grapevines without a decline in yield, thereby increasing water use efficiency (WUE). The principle of PRD is to keep part of the root system at a constant drying rate to produce soil derived signals to above-ground plant organs to induce a

Aim: The regulation of the vegetative-reproductive balance of a vineyard is a critical aspect for the quality of grapes. Early leaf removal, generally applied before the phenological stage of flowering, is mainly used as a technique to control yield and improve grape health, aimed at increasing the quality of the wine.

The principles of virological control on different types of grapevine collections and plantations are summarized.

It is important to quantify the effect of potential crop on vine water constraint in order to adapt vine-growing consulting and vine management to the Mediterranean climate conditions
