Proposal of zonification and characterization of terroirs in the Yalde-Najerilla-Uruñuela vine growing area (DOC Rioja, Spain), based on the soil influence

Abstract

Natural Terroir Units (NTU) are being delimited in vine growing area DOCa Rioja, in collaboration with Uruñuela Cooperative, to characterized specific and singular Tempranillo (Vitis vinifera, L.) wines. NTU selection is based on detailed cartography (1:20.000), managed by the Soil Information System of La Rioja (SISR), and in the analysis of pedologic, climatic, lithologic, and relief features of Najerilla Valley.
The five NTU, placed on river and torrential platforms with similar lithology of original materials, have been selected with series of soils belong to the Alfisol, Inceptisol and Mollisol orders. The main purpose of this project is to measure the influence produced by soil properties of each series of soil (effective depth, water reserve, clay and carbonates percentage, potassium and magnesium) in musts and wines of this vine growing area.

Influence of climatic conditions on grape composition of Tempranillo in La Mancha DO (Spain)

The aim of this work was to analyze the variability in grape composition of the Tempranillo cultivar related to climatic conditions, in La Mancha Designation of Origin. Grape composition (sugar content, total acidity, pH, malic acid, and total and extractable anthocyanins) recorded during ripening, were analysed for the period 2000-2019. The weather conditions at daily time scale, recorded during the same period, were also evaluated. The relationships between grape parameters with climatic variables related to temperature and to water deficits, referring different periods between phenological events along the growing cycle, were evaluated using regression analysis. High variability in grape composition was observed in the period analysed. Total acidity varied between 3.7 and 7.3 gL-1 while malic acid varied between 1.2 and 4 gL-1. The extractable anthocyanins ranged between 526 and 972 mgL-1, and total anthocyanins ranged between 922 and 1388 mgL-1, being the lowest values recorded in the hottest year (2017). Total acidity decreased 0.77 gL-1 for an increase of 100 GDD, while malic acid decrease in 0.42 gL-1 for the same GDD increase, being the period between veraison and harvest the one that seemed to have higher influence on acidity. In addition, it was confirmed that increasing water deficits decreased acidity. Total and extractable anthocyanins increased in about 210 and 105 mgL-1, respectively, with an increase of 100 GDD from veraison to harvest, and the increase in water deficits favour the increase of anthocyanins, both total and extractable anthocyanins. Total and extractable anthocyanins concentration increased in 35 and 22 mgL-1 per an increase of 10 mm in the water deficit. These results can be of interest to understand the potential changes that grapes composition may suffer under future warmer climates.

Quantitative nuclear magnetic resonance spectroscopy 2H(D)-qNMR in the study of deuterium distribution in intracellular water and fermentation products of grape carbohydrates using ethyl alcohol as an example

The paper presents results that develop the results of studies carried out in 2022-2023 under the OIV grant on the topic of distribution of deuterium (2H(D)) in the intracellular water of grapes and wines, taking into account the impact of natural, climatic and technogenic factors using quantitative nuclear magnetic resonance spectroscopy (qNMR).

Volatile organic compounds: a role in elicitor-induced resistance of grapevine against pathogens?

As Vitis vinifera varieties are susceptible to fungal diseases, numerous chemical treatments are generally required to ensure the quantity and quality of the harvest. However, in the context of sustainable viticulture, there are increasing societal request, political incitation, and winegrowers’ awareness to reduce the use of pesticides.

Shades of shading: chemical and sensory evaluation of riesling grown under various shading techniques

Sun exposure is needed for balanced grape ripening and sugar accumulation but is also one of the main drivers for a premature Riesling ageing

Aroma profile evaluation in whole grape juices

Table grapes (Vitis labrusca and hybrids) are widely cultivated in Brazil [1] due to the climate, their resistance to disease and the way they are consumed and commercialized, either in-natura or for processing, producing whole juices, jams and table wines.
