Historical terraced vineyards – heritage and nature conservation strategies

Abstract

Historical terrace vineyards are simultaneously impressive documents of the human inclination to design, sites for the production of high quality wines and habitats for a rich variety of flora and fauna. In the past they have often also been the setting for questionable developments. Radical land consolidation processes rendered these sites high yield utilisation areas, but also resulted in their conversion to plain monocultures. Where the rationalisation of terrace vineyards was not profitable, these were often abandoned entirely. Only a modest proportion of the vineyards have managed to retain their historical character. It is necessary to develop strategies for the sustainable use of these sites in order to secure first and foremost their very existence, but also their historical, social, economic and ecological worth.
The aim of the transdisciplinary ‘HISTORISCHE WEINBERGE’ project is to heighten both users’ and conservationists’ awareness of the values associated with these landscapes, so as to counter an unsustainable intensification of land use, or alternatively the total abandonment of these areas. A guideline for the conservation of the vineyards is being developed in cooperation with winegrowers and representatives from politics, nature protection and heritage conservation. The guideline will be developed on the basis of criteria corresponding to both use and protection needs. This process seeks to harmonise the interests of the various actors and to optimise the path towards an integrated approach to the tending of the cultural landscape. The knowledge and the perspectives of the stakeholders are being continuously assessed through interviews, working groups and local events so as to ensure the practical relevance of the project.

Factors influencing cover crop water competition in vineyards and implications for future drought adaptation

Vineyard water management in Australia is often associated with irrigation in warm and hot climates, but in cooler regions the larger share of the seasonal water demand is met by rainfall.

Colloidal stabilization of young red wine by Acacia Senegal gum: the major implication of protein-rich arabinogalactan-proteins

Acacia senegal gum (Asen) is an edible dried gummy exudate [1] added in young red wines to ensure their colloidal stability, precluding the precipitation of the coloring matter. Asen macromolecules, belonging to the arabinogalactan-protein (AGP) family [2], are hyperbranched, charged and amphiphilic heteropolysaccharides composed especially of sugars (92-96 %) and a small fraction of proteins (1-3 %). Asen is defined as a continuum of macromolecules that could be separated into three fractions by hydrophobic interaction chromatography (HIC) [3-4]. HIC-F1 (85-94 % of Asen), HIC-F2 (6-18 % of Asen) and HIC-F3 (1-3 % of Asen) are named and classified in that order according to their protein content, and then a growing hydrophobicity. The efficiency of Asen towards the coloring matter instability is evaluated according to an “efficacy test” that consists to determine the Asen quantity required to prevent the flocculation by calcium of a colloidal iron hexacyanoferrate solution (International Oenological Codex).

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).

Linear sweep voltammetry to classify and characterize the antioxidant properties of tannins

In recent years, numerous studies have been carried out at the OIV on oenological tannins, both with regard to oenological properties and methods of characterization. The results of these recent studies have led to the revision of the general monograph and the drafting of four new monographs, one for each of the four chemical classes into which the tannins have been grouped: ellagitannins, gallotannins, procyanidins/prodelphinidins, profisetinidins/prorobinetinins.

A zoning study of the viticultural territory of a cooperative winery in Valpolicella

The Valpolicella hilly area, north of Verona, is highly vocated for viticulture but its vineyards are sometimes characterized by very different soil and microclimate conditions which can greatly affect their oenological potential.
