A multilayer interactive web map of the wine growing region carnuntum with emphasis on geochemical and mineralogical zoning

Abstract

During a three-year study the vineyards of the wine-growing region Carnuntum have been investigated for their terroir characteristics (climate, soil, rocks) and major viticulture functions. As an outcome of the study, various thematic layers and geodata analyses describe the geo-environmental properties and variability of the wine growing region and delimit homogenous multilayer mapping units by using a Geographic Information System.

These results have been converted to multilayer web services which are presented with a web map application (http://www.geologie.ac.at/en/research-development/mapping/substrate-floor/naturraum-carnuntum/).

The web map gives access to grouped thematic layers which represent climatic parameters (e.g. HUGLIN-Index, risk of frost), soil physics (e.g. available water capacity), soil chemistry and nutrients, rock geochemistry, geology, mineralogy and apparent resistivity maps. Using the web map interface one is able navigate on-screen to areas of interest and select the desired layers in any combination and transparency for display on aerial images. As the study results are made available to winemakers of the region and to the general public, the web map shall primarily serve as an information tool but is also intended to promote and communicate scientific research for the exploration of winegrowing regions.

The functions of the web map focus on the evaluation of the vertical and lateral variations of rocks and soils. In the study area more than 200 samples were taken by drilling or at sampling pits and analysed for grainsize distribution, clay mineral and bulk mineral content and whole rock geochemistry. By exploratory data analysis of the sample data the parameters were used to compare regional areas and lithostratigraphic units with graphs and descriptive statistics. The results of the exploratory data analysis contribute to the characterization of the stratigraphic units and the zoning of the study region.

Terroir and Typicity: proposed definitions for two essential concepts in the understanding of Geographical Indications and sustainable development

The content of this communication arises from the deliberations of a working group mandated within the framework of the INRA-INAO 2000-2003 research convention, which brought together INAO representatives and researchers who had worked on AOCs or PGIs, in disciplines from the sphere of the humanities (consumer science, marketing, rural development) and biotechnical sciences (agronomy, animal production science, technology, biochemistry).

Predicting oxygen consumption rate by tannins through sweep linear voltammetry and machine learning models

Nowadays, it is well known that oxygen significantly impacts wine quality. The amount of oxygen wine consumes during the winemaking process depends on several factors, such as storage conditions, the number of rackings, the materials used for aging, and the type of closure chosen for bottling.

Technological possibilities of grape marc cell walls as wine fining agent. Effect on wine phenolic composition

Fining is a technique that is used to remove unwanted wine components that affect clarification, astringency, color, bitterness, and aroma. Fining involves the addition of adsorptive or reactive material in order to reduce or eliminate the presence of certain less desirable wine components and to ensure that a wine remains in a particular stable state for a given period of time Recently concerns have been raised about the addition of animal proteins, such as gelatin, to wine due to the disease known as bovine spongiform encephalopathy (Mad Cow disease). Although the origin of gelatins has been moved to porcine, winemakers are asking for substitute products with properties and application protocols similar to the traditional animal-derived ones, making the use of plant-derived proteins in fining a practically viable possibility. As a consequence, various fining agents derived from plants have been proposed, including proteins from cereals, legumes, and potato.
