Zonificación climática de las D.O. Rueda y Toro y vinos de la tierra de medina del campo

Climate change increasingly leads to altered growing conditions in viticulture, such as heat stress, drought or high infection pressure favoring pathogen infection.

Vine cultivar Mourvèdre is present all around the Mediterranean area and is interesting for its tannins and the specificity of its aromas.

The seasonal’s climatic conditions determine the composition of grapes at harvest as they affect the vine’s physiology and development. High temperatures during the grape ripening period cause a high accumulation of sugars and degradation of fruit acidity ,and alter the synthesis of polyphenols. Therefore, some vineyard management can be applied in order to modify grapevine impact on climate variability. One example is the pre-pruning at the beginning of grape ripening, which can delay the ripening period and modify the composition of the grapes at harvest. This work aims to evaluate the pre-pruning field technique on yield components and alcohol content in wines of Tannat and Merlot varieties.

Winemaking is a globally significant industry in the field of food technology (218 mhL of wine estimated for 2024 harvest) [1], which activity produces tons of by-products annually, including pomace (pulp, stems, seeds, skins), lees, organic acids, CO2, and water [2].

Conventional viticulture improved the quality of production, but the economic costs can be unsustainable. Today, producers need to consider consumers’ demands for healthy, eco-friendly products. Institutions promote sustainable agriculture, with regenerative agriculture being the latest generation of methodologies focused on recovering losses and ensuring future sustainability. The revine project studies regenerative agricultural technology applied in mediterranean countries to provide precise indications for soil processing and effective vineyard treatments.
