Organic and biodynamic sustainable productions and effect on eligibility and peculiarity of a typical wine

Abstract

The wine industry is currently shifting toward more sustainable production systems. There are many reasons for this as the interest of people over climate change and, consequently the wine consumer’s choice toward organic and biodynamic, reduced carbon-footprint, vegan and other environmentally friendly wines. While the viticultural effects of biodynamic and organic practices on wine grapes have been investigated, there is a lack in literature on the general effect on the final quality of wine.

For this purpose, this study sought to evaluate the impact of the organic, biodynamic and conventional production processes on the eligibility and peculiarity of a typical wine, such as Chianti DOCG: commercial Chianti DOCG wines from 2016 and 2017 harvest were selected based on their production management including organic, biodynamic and, conventional. The global quality of a typical wine was defined by three different profiles: the eligibility profile (chemical characteristics such as alcohol concentration, total acidity, pH, and phenolic concentration), the peculiarity or typicality profile defined by the cultivar (aromatic characteristics that originate from the grapes), and the style profile (characteristics that result from winemaking methods). Chemical and sensory analyses were carried out to define the eligibility and typicality profiles of the wines and to evaluate their correlation with the different production techniques. The statistical elaboration of the chemical and sensory data underlined that generally the different wine production techniques did not yield any systematic differences on the eligibility and typicality profiles, except for the higher values of color intensity and polyphenols contents of the organic wines.

Investigating kokumi flavour oligopeptides in wine

Kokumi is a complex sensation perceived as enhanced palatability. Under the influence of kokumi substances, foods/beverages tastes become more flavorful with increased intensity, spread, continuity, richness, harmony, and punch which are the six related characteristics corresponding to the Kokumi sensory concept [1].

Untargeted LC-HRMS analysis to discover new taste-active compounds in spirits.

​For several years, the chemistry of taste has aroused high interest both from academics and industrials. Plant kingdom is a rich and reliable source of new taste-active compounds. Many sweet, bitter or sour molecules have been identified in various plants [1]. They belong to diverse chemical families and their sensory properties are strongly affected by slight structural modifications. As a consequence, the investigation of natural taste-active products in a given matrix appears as a major challenge for chemists. Such studies are particularly relevant in oenology since they allow a better understanding of wine and spirit taste.

Simulated climate change in a Mediterranean organic vineyard altered the plant physiology and decreased the vine production

This study focuses on investigating the effects of climate change on the plant physiology and berries of Vitis vinifera cv “Monastrell” in a commercial vineyard managed organically in Southeastern Spain (Jumilla, Murcia). For this purpose, open top chambers and rainout shelters were employed to simulate warming (~2-7 ºC, W) and rainfall reduction (~30%, RR) respectively. Additionally, a combination of both treatments (W+RR) was employed. Vines without either top chambers or rainout shelters were considered as control (C). The experiment was established in February of 2023. Predawn leaf water potential (measured using a pressure chamber), stomatal conductance (assessed with a porometer at mid-morning) and leaf chlorophyll and flavonoid content (measured using the Dualex® leaf clip sensor) were analyzed at veraison (5 months after the installation of structures).

Structural composition of polymeric polyphenols of red wine after long-term ageing: effect of vinification technology

Aged red wines possess phenolic composition very different from young ones due to the transformations among native grape phenolics and the formation of new polymeric polyphenols during aging process.
