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.

Gastrointestinal digestion of wine sulphites and their effects on human gut microbiota

Sulphites are by far the most widely used additive in the wine industry. In relation to health, the interaction of sulphites with the gut microbiota has not been addressed so far. Following the consumption of wine and other sulphite-containing foods, the gastrointestinal tract and the microbiome are one of the first barriers that these compounds face in the human organism. In this study, we used a previously validated gastrointestinal digestion model (SIMGI®) [1,2] to evaluate the effect of intestinal digestion of wine sulphites on the gut microbiome.

Genetic and hormonal regulation of grape berry cuticle formation

The plant surface typically comprises of various epidermal cell types which synthesise and deposit a protective waxy layer known as the cuticle. The cuticle is a significant contributor to important crop traits related to drought tolerance, biotic stress, postharvest fruit quality as well as providing structural support. In this work we have investigated grape berry cuticle formation in the context of the accumulation of anti-fungal specialised metabolites and the ability of the cuticle to structurally cope with the rapid expansion of ripening berries. Metabolic QTL analysis was performed in a grapevine cross population, using chemical profiling data collected via GC-MS analysis for cuticular waxes.

Above and below–research challenges for the future of winegrape production

Grapevines interact with the climate (aboveground) and the soil (belowground), affecting the characteristics of winegrapes produced. These interactions are impacted by climate change, the erosion of biodiversity, and losses of soil organic matter (SOM).

Effects of water and nitrogen uptake, and soil temperature, on vine development, berry ripening and wine quality of Cabernet-Sauvignon, Cabernet franc and Merlot (Saint-Emilion, 1997)

Wine quality depends largely on berry ripening conditions in relation to soil and climat. The influence of the soil has been studied in Bordeaux since the early Seventies (SEGUIN, 1970; DUTEAU et al., 1981; VAN LEEUWEN, 1991; VAN LEEUWEN et SEGUIN, 1994) and, more recently, in the Val de Loire (MORLAT, 1989), the Alsace (LEBON, 1993) and the Costières de Nîmes regions (MARTIN, 1995).

Key genes in rotundone biosynthesis are affected by temperature, light, water supply, and nitrogen uptake

Rotundone accumulation and biosynthesis is a complicated process. Previous research highlighted that these phenomenons were affected under ecophysiological conditions by viticultural practices (e.g. defoliation or irrigation). Individually, these practices often impact several abiotic factors that are difficult to separate such as temperature, water or nitrogen status, or radiation. Such dissociation can be achieved under controlled environmental conditions using potted vines.
