Il monitoraggio meteorologico come strumento per la gestione della variabilità climatica in Franciacorta

Abstract

[English version below]

Nel 2007 è stata avviata una ricerca nell’areale di produzione del Franciacorta DOCG che ha riguardato un ampio numero di vigneti di Chardonnay con riferimento ai quali sono stati acquisite le serie storiche dal 2001 relative a (i) decorso delle epoche fenologiche, (ii) curve di maturazione e (iii) dati prodotti dalla rete meteorologica consortile. Tali dati hanno permesso di produrre un modello empirico agrofenologico relativo allo Chardonnay nell’areale considerato e di calibrare e validare un modello meccanicistico di simulazione della produttività primaria, chiamato SIM_PP.

In 2007 a research was started on an high number of vineyards in the Franciacorta AOC area. From 2001 to 2009, phonological stages records and ripening kinetics data were collected. Starting from phenological data, an empiric agrophenological model was build, in order to estimate principal stages by using daily cumulated temperature. Furthermore, ripening kinetics were compared to mechanicistic model simulations (SIM_PP, Mariani and Maugeri, 2002). Starting from air daily temperatures, SIM_PP simulates the Net Primary Production, allocation dynamics in sink organs and the sugars storage in berries, using a mechanism based on transpiration and mass transport flux.
The comparison between real in-field situation and gathered simulations allowed to evaluate mechanicistic and empirical models performance.

Terroir analysis and its complexity

Terroir is not only a geographical site, but it is a more complex concept able to express the “collective knowledge of the interactions” between the environment and the vines mediated through human action and “providing distinctive characteristics” to the final product (OIV 2010). It is often treated and accepted as a “black box”, in which the relationships between wine and its origin have not been clearly explained. Nevertheless, it is well known that terroir expression is strongly dependent on the physical environment, and in particular on the interaction between soil-plant and atmosphere system, which influences the grapevine responses, grapes composition and wine quality. The Terroir studying and mapping are based on viticultural zoning procedures, obtained with different levels of know-how, at different spatial and temporal scales, empiricism and complexity in the description of involved bio-physical processes, and integrating or not the multidisciplinary nature of the terroir. The scientific understanding of the mechanisms ruling both the vineyard variability and the quality of grapes is one of the most important scientific focuses of terroir research. In fact, this know-how is crucial for supporting the analysis of climate change impacts on terroir resilience, identifying new promised lands for viticulture, and driving vineyard management toward a target oenological goal. In this contribution, an overview of the last findings in terroir studies and approaches will be shown with special attention to the terroir resilience analysis to climate change, facing the use and abuse of terroir concept and new technology able to support it and identifying the terroir zones.

Extraction-modelling approach demonstrates grapevine rooting patterns varies significantly as a result of contrasting ground management and growing environment in cover cropped vineyards

The use of cover crops in viticulture has increased in recent decades as growers seek to reduce herbicide use, improve soil organic matter and biodiversity, and minimize soil-related agronomic issues such as compaction and erosion.

Optimized grape seed protein extraction for wine fining

The extraction of proteins from grape seeds represents a promising strategy to revalorize wine industry by-products. As a natural endogenous fining agent, grape seed protein (GSE) offers an effective solution for wine clarification [1] without requiring label declaration.

What drives Indications of Geographical Origin protection and governance mechanisms in the U.S. and European contexts? A contribution of the social sciences

There are fundamentally two different ways in which indications of geographical origin (igos) can be protected. The us approach favors the pre-existing trademark system through collective marks (cms), while the eu approach favors a maximalist approach via a sui generis system which promotes appellations of origin (aos). A consensus however emerges regarding the fundamental protection of origin against misleading, confusing and dilutive uses. Previous literature discusses these competing igo logics from historical, legal and international trade perspectives. In this paper, we depart from the field of social sciences, in particular from recent advancements in the well-established literature on proximities, in order to provide a reflection on the different logics underpinning the aos and cms systems.

Diurnal cycles of grapevine leaf water potential under field conditions

Les cycles journaliers du potentiel hydrique foliaire (Ψl) ont été établis toutes les heures, pour différents stades phénologiques, sur deux localités et en fonction de différentes mesures de la température de l’air et du déficit en pression de vapeur (VPD). De faibles valeurs pour ces 2 paramètres ont été enregistrées tout au long de la saison à
