What triggers the decision to ripen 

Rootstocks not only provide tolerance to Phylloxera, but also ensure the supply of water and mineral nutrients to the whole plant. Rootstocks are an important way of adapting to environmental conditions while conserving the typical features of scion varieties. We can exploit the large diversity of rootstocks used worldwide to aid this adaptation. The aim of this study was to characterise rootstock regulation of scion mineral status and its relation with scion development.

The overall quality of fine wines is linked to the development of “bouquet” during wine bottle ageing (1). Bordeaux red wine ageing bouquet is defined by the association of several odours

There are fundamentally two different ways in which indications of geographical origin (igos) can be protected. The us approach favors the pre-existing trademark system through collective marks (cms), while the eu approach favors a maximalist approach via a sui generis system which promotes appellations of origin (aos). A consensus however emerges regarding the fundamental protection of origin against misleading, confusing and dilutive uses. Previous literature discusses these competing igo logics from historical, legal and international trade perspectives. In this paper, we depart from the field of social sciences, in particular from recent advancements in the well-established literature on proximities, in order to provide a reflection on the different logics underpinning the aos and cms systems.

The actual climate changes, together with the strong regulation of the European Union and Spanish government, in search of sustainable viticulture, have forced the recovery of minority varieties, expanding the range of grape varieties, as well as the possible development of wines with unique profiles. In the Ribeira Sacra DO (Spain), a comparative study of the agronomic and qualitative behavior of the ‘Branco lexítimo’ variety has been carried out, compared to the majority white variety in the DO: ‘Godello’, located in the same study plot, with identic soil and climatic conditions. The study contemplated the analysis of phenology and leaf water potential, as well as the productive results and the analysis of the must quality, during four seasons: 2018 – 2021.

Irrigation of vineyards is a matter of controversial arguments at areas of high quality wine production. Besides, the effects of the water in the plant are closer related to the water availability than to the irrigation regime.
