Application of GiESCO “bio-metaethics” charter in practice: the “direct” involvement of vine grower, winemaker, society

Abstract

On the basis of a direct agreement between the GiESCO and the vine grower, the winemaker and the consumers (individual; company; public or private organizations), the communication on the content of the charter can be done as follows:

• Commitment to respect the basic rules of the GiESCO “BIO – MetaEthics” charter.

1/ Put Mankind in the depth of all concerns in a universal context: (grower, consumer, citizen, work valuing, education, security)

2/ Insure minimum impact on environment by optimizing cultivation technics: (maximum of natural biodegradable products, friendly practices, short channels, renewable energies, terroir sustainability)

3/ Warrant transparency and evaluation of all operations: (traceability of the production line, complete analyses of the products, use of secure scientific methods, wide communication)

• Specific choices made by the vine grower, the winemaker and the consumer (individual; company; public or private organizations) respecting the basic rules.

A precise example is taken in North – East of Italy where activities were conducted in a farm located both in the hillside in the well-known ‘terroir’ of Prosecco area, and in the flat area, and differently managed according to the location.

It has been verified with successful application, that this ” Charter of Direct Sustainability BIO – MetaEthics” can be used anywhere, in conventional or otherwise certified companies (for example: “Organic”, “VIVA”, …), in which the producers want to “certify” their particular characteristics such as:

1-the use of original, innovative, sustainable technics referring to 4.1C guide:

1.1-training systems and winter pruning systems such as: “Prosecco of Prosecco 4.1 C”, “Prosecco of Cartizze

4.1C”, “Prosecco-Latnik 4.1C”, which, among other things, allow not to be damaged by wild boar, roe deer, deer, birds, … and this without altering natural life;

1.2-management of the soil, of the grass, of the plant for example: 1.2.1-completely replacing chemical weeding with perennial grasses without mowing or mowing the grass, but only when and where objectively

“4.1C” this cannot be avoided, 1.2-2-eliminating or drastically reducing interventions on the ground and on the plant such as shoot positioning, topping and edging, for example in companies certified by known Italian certifications that do not include these aspects, 1.2.3-setting a phytosanitary defense applicable anywhere, also, in populated areas;

2-valuing and further personalizing the existing certifications, for example by certifying “GiESCO BIO -MetaEthics” insisting on the use of resistant varieties and the absence of copper residues in companies already certified “Organic”.

Obviously, the “Charter of Direct Sustainability BIO – MetaEthics” of the GiESCO fits the “Direct 4.1C Certification” and also the relative “Direct Guarantee 4.1C”: technical, economic, environmental, social, existential, ethical.

Investigating the impact of grape exposure and UV radiations on rotundone in Vitis vinifera L. Tardif grapes under field trial conditions

Rotundone is the main aroma compound responsible for peppery notes in wines whose biosynthesis is negatively affected by heat and drought. Through the alteration of precipitation regime and the increase in temperature during maturation, climate change is expected to affect wine peppery typicality. In this context there is a demand for developing sustainable viticultural strategies to enhance rotundone accumulation or limit its degradation. It was recently proposed that ultraviolet (UV) radiations could stimulate rotundone production. The aim of this study was to investigate under field trial conditions the impact of grape exposure and UV treatments on rotundone in Vitis vinifera L. Tardif, an almost extinct grape variety from south-west France that can express particularly high rotundone levels. Four different treatments were compared in 2021 to a control treatment using a randomised complete block design with three replications per treatment. Grape exposure was manipulated through early or late defoliation. Leaf and laterals shoots were removed at Eichorn Lorenz growth stages 32 or 34 on the morning-sun side of the canopy. During grape maturation, UV radiations were either reduced by 99% by installing UV radiation-shielding sheets, or applied four times using the Boxilumix™ non thermal device (Asclepios Tech, Tournefeuille) with the aim of activating plant signalling pathway. Loggers displayed in solar radiation shields were used to assess the effect of such shielding sheets on air temperature within the bunch zone. The composition of grapes subjected to these treatments will be soon analysed for their rotundone content and basic classical laboratory analyses. Grapes will be harvested to elaborate wines under standardized small-scale vinification conditions (60kg) that will be assessed by a trained sensory panel.

Impact of yeast derivatives to increase the phenolic maturity and aroma intensity of wine

Using viticultural and enological techniques to increase aromatics in white wine is a prized yet challenging technique for commercial wine producers. Equally difficult are challenges encountered in hastening phenolic maturity and thereby increasing color intensity in red wines. The ability to alter organoleptic and visual properties of wines plays a decisive role in vintages in which grapes are not able to reach full maturity, which is seen increasingly more often as a result of climate change. A new, yeast-based product on the viticultural market may give the opportunity to increase sensory properties of finished wines. Manufacturer packaging claims these yeast derivatives intensify wine aromas of white grape varieties, as well as improve phenolic ripeness of red varieties, but the effects of this application have been little researched until now. The current study applied the yeast derivative, according to the manufacture’s instructions, to the leaves of both neutral and aromatic white wine varieties, as well as on structured red wine varieties. Chemical parameters and volatile aromatics were analyzed in grape musts and finished wines, and all wines were subjected to sensory analysis by a tasting panel. Collective results of all analyses showed that the application of the yeast derivative in the vineyard showed no effect across all varieties examined, and did not intensify white wine aromatics, nor improve phenolic ripeness and color intensity in red wine.

Extreme canopy management for vineyard adaptation to climate change: is it a good idea?

Climate change constitutes an enormous challenge for humankind and for all human activities, viticulture not being an exception. Long-term strategic changes are probably needed the most, but growers also need to deal with short-term changes: summers that are getting progressively warmer, earlier harvest dates and higher pH in musts and wines. In the last 10-15 years, a relevant corpus of research is being developed worldwide in order to evaluate to which extent extreme canopy management operations, aimed at reducing leaf area and, thus, limiting the source to sink ratio, could be useful to delay ripening. Although extreme canopy management can result in relevant delays in harvest dates, longer term studies, as well as detailed analysis of their implications on carbohydrate reserves, bud fertility and future yield are desirable before these practices can be recommended.
