Zoning influence in chromatic parameters in Monastrell grape

Abstract

Zoning analysis determine homogeneous areas principally from the point of view of the medium, giving as a result a map which cartographic units synthesize the relations between the edaphic factors; morphological factors of the soil and climatic factors. The combination of these types of parameters allows to obtain maps of suitability of the optimum areas for the crop of the vineyard. At present it has been delimited and characterized eight grape areas belonging to the D.O. Jumilla. The chosen plots has been: Varahonda, Cañada del Judío, Cañada de Albatana, El Carche, Rubializas, Agüeros, Cortijo del Agrio and Casa Vistalegre. 
The determined parameters are: Phenological parameters: Dates of sprouting, flowering, veraison, and harvest. Chemical parameters during maturation: total phenolic compounds, anthocyanins to pH 1 (extractable anthoc.) and anthocyanins to pH 3 (Total anthoc.), seed ripeness (MP) and index of cellular ripeness (IMC). 
As for the determination of chromatic parameters and of extractability, in the plot of Cortijo del agrio the biggest quantity of anthocyanins has been obtained on having finished the period of ripening, on the other hand the plot of Cañada del Judio is the one that has obtained the highest values of extractable polyphenols. In our study, for the IMC lower value has been obtained for the plot located in Cañada del Judio and the highest value for the plot of Cortijo del agrio. As for seed ripeness Rubializas and Cortijo del agrio are the plots that obtained the lowest values.

Assessment of the optimal number of observations in the study of vineyard soil (Rigosol)

A study of soil pH on the experimental field resulted in a high variability of pH on a very small scale. This kind of heterogenity in soil pH have effects on growth of two grapevine varieties on rootstock Kober 5BB

Geological history and landscape of the Coastal wine-growing region, South Africa

The geology of the Western Cape testifies to the former existence of a late Precambrian supercontinent, its fragmentation, the closure of an ocean between the South African and South American continental precursors (Kalahari and Rio de la Plata cratons), the accumulation of marine sediments and limestones, and their compression during a collision between these cratons

What happens with the glutathione during winemaking and the storage of the wine?

We tried to give a part of the answer to this question by monitoring glutathione during winemaking and storage. The novelty of our approach is to quantify simultaneously the three known forms of glutathione: free glutathione (GSH), oxidized form (GSSG) and glutathione-S-sulfonate (GSSO3H).

Mineral-wine profile and AI: wine authentication and identification

Enhancing the mineral wine profile: from authentication to identification by artificial intelligence for enhanced security. Analysis of a wine’s mineral concentration profile provides a distinctive fingerprint for each cuvée. Unlike organic profiles, this identification signature remains stable over time and can be deciphered using direct analysis by inductively coupled mass spectrometry (icp-ms).

The classification of enological tannins has gained importance following the OIV’s requirement to include their botanical origin on product labels (OIV-OENO 624-2022).
