Geochemistry of Vrbničko Polje (Croatia) winegrowing site

Abstract

A multi-element pedo-geochemical survey was carried out in Vrbničko polje vineyards on the Krk Island, Croatia. This Mediterranean winegrowing site is famous by Žlahtina wine production. The objectives of this study are (i) to describe characteristics of the site related to climate, topography, geology, soil and geochemistry and (ii) to integrate data on soil quality using GIS which can be applied with management information systems Two soil profiles were excavated and examined, and dominant soil type was determined, as well as physical and chemical characteristics of soil. Topsoil (0-30 cm) and subsoil (30-60 cm) samples were collected from 26 locations inside the site. Total metal contents (Al, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, P, Pb, S, V, Zn) were determined using ICP-OES after aqua regia extraction. A geospatial database was compiled in GIS, and after applying statistics and geostatistisc, the maps of trace metals distribution have been produced. Accumulation of copper in soil, determined in this research, is the most common effect of continuing fertilization and protection against diseases and pests in vineyards. High nickel and chromium concentrations seem to be of the geogenic origin. Associations of heavy metals with the selected soil properties explain the preferential feature of metal retention in soil.

Using elicitors in different grape varieties. Effect over their phenolic composition

Phenolic compounds are very important in crop plants and have been the subject of a large number of studies. Three main reasons can be cited for optimizing the level of phenolic compounds in crop plants: their physiological role in plants, their technological significance for food processing, and their nutritional characteristics1 Indeed, an enormous diversity of phenolic antioxidants is found in fruits and vegetables, and their presence and roles can be affected or modified by several pre- and postharvest cultural practices and/or food processing technologies (Ruiz-García et al. 2012, Goldman et al. 1999, Tudela et al. 2002). In winegrapes, the technological importance of phenolic compounds, mainly flavonoids, is well-known.

White wine lees: unlocking the relationship between chemical composition and antioxidant potential

The wine-making process generates numerous by-products at each stage (crushing, fermentation, ageing), including wine lees, which account for almost 25% of the total quantity.

Genetic traceability of the varietal origin of wines: a robust application for must and wines during alcoholic fermentation

Industry and regulatory agencies have developed regulations to ensure authenticity and compliance with wine composition limits. However, this can be truncated by the absence of simple and robust analytical methodologies, uninfluenced by the environment, different oenological techniques and cultural practices. Genetic fingerprinting is the most powerful tool for unequivocal varietal identification; it is not affected by the environment or agronomic practices; however, its usefulness in musts and wines has been controversial and there is currently no routine certification of varietal origin based on DNA analysis.

100 ans d’évolution des règles relatives à l’encépagement des AOC viticoles françaises : quelles perspectives face aux enjeux contemporains

To characterize a wine, the most frequently used criteria describe its color, its origin, the grape varieties from which they come, or even for white wines its residual sugar content (dry, semi-dry, sweet). In france, the system of appellations of origin set up in 1919 was initially based solely on the notoriety and origin of the wines. But given the unfavorable consequences that this lack of details generated, the public authorities quickly integrated in 1927 into the “capus” law criteria for access to designations of origin, relating to the specific characteristics of the soils of the vineyards and the grape varieties used, in particular exclusion of interspecific hybrid varieties. In 1935 the creation of the aoc system confirmed the interest in precisely defining all the production conditions that must be implemented to be able to claim the benefit of an aoc, and grape varieties were an essential condition for acquisition.
