Results of late-wurmian to present-day climatic-geological evolution on to spatial variability of pedologic-geological characters of the AOC Gaillac terroirs (Tarn, Midi-Pyrénées)

Cell death in Vitis vinifera L. berries late in ripening and berry shrinkage (loss of mass) can decrease yield and reduce grape quality in cultivars such as Cabernet Sauvignon

Defined the new paradigm, the applied philosophy, the methodology, the algorithm of the “Charter for Universal Holistic MetaEthic Sustainability 4.1C17.18”, research has continued to define and write, an
handbook that should be:”Complete Universal Holistic MetaEthics 4.1C of descriptors” of the “Charter for Sustainability Universal Holistic MetaEthic 4.1C17.18” with basic and applicative indexing. In these activities and research we have involved over 3500 Italian and non-Italian people from the research world to simple but educated, enlightened and enlightening citizens and we have analyzed over 180000
entries concerning the descriptors above, which represent the basic “descriptors”.

Agrivoltaics (AV), the innovative dual-use of land for agriculture and photovoltaic energy production on the same land, offers a promising solution to the challenges of expanding renewable energy without compromising valuable agricultural land.

Acidity adjustments are key to microbial control, sensory quality and wine longevity. Acidification with cation exchange resins -in acid cycle- offers the possibility to reduce the pH by exchanging wine cations, such as potassium (K+), for hydrogen ions (H+). During the exchange process, the removal of potassium and calcium ions contributes to limiting the formation of tartrate salts, thus offering an alternative solution to conventional methods for tartrate stability. Moreover, the reduction of wine pH and the removal of metals catalyzers (e.g. iron) could positively impact the wine’s oxidative stability. Therefore, the aims of this work were (a) to optimize the ion exchange process by testing different volumes and concentrations of sulfuric acid (H2SO4) during the acid cycle, (b) evaluate the effects of the ion exchange process on the formation of tartrate salts, and (c) analyze the oxidative stability of the treated wines.

Blending wines from different grape varieties is often used in order to increase wine complexity and balance. Due to their popularity, several types of blends such as the Bordeaux blend, are protected by PDO legislation.
