Application to the wine sector of European Convention on the landscapes

The recent effects on temperature and rainfall caused by global warming pose a serious threat to the wine industry worldwide, mainly in terms of a loss of quality in the wines produced.

Brandy de Jerez (BJ) is a spirit drink made exclusively from spirits and wine distillates and is characterized by the use of casks for aging that previously contained Sherries. The quality and sensory complexity of BJ depend on the raw materials and some factors: grape variety, conditions during processing the wine and its distillation, as well as the aging in the cask. Therefore, the original compounds of the grapes from which it comes are of great interest (1 y 2) being in most cases the Airén variety. Their relationship with the quality of the musts and the wines obtained from them has been studied (3) and varies each year of harvest depending on the weather conditions (4).

Flavescence dorée (FD) is the most serious grapevine yellows disease in Europe. It is caused by phytoplasmas which are transmitted from grapevine to grapevine by the leafhopper Scaphoideus titanus.

The International Phylloxera Genotype Database “PHYLLI” which is supported by the 2014 ISHS Phylloxera group describes Grape Phylloxera (Daktulosphaira vitifoliae) genotypes, which are genotyped by seven SSR markers (Dvit6, DVSSR4, DV4, DV8, Phy_III_36, Phy_III_55, Phy_III_30). The samples are standardised by single founder lineages, that are equally biotyped.

The availability of water in the soil and the water status of the vineyard are proving to be determining factors for crop management in the current context of climatic variation
