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.

New oenological technology for adaptation to climate change: reduction of alcohol content during wine fermentation through stripping, with fermentative CO2

The capture and valorization of fermentative CO2 have been developed for several years by the company w platform for internal uses, notably in the cellars: inerting, cooling, reduction of water consumption, extraction, with aroma valorization. In a context of climatic warming during the vegetative cycle, grapes are currently harvested with a significant sugar concentration, a phenomenon that is expected to intensify in the coming decades. The high alcohol content of the resulting wines goes against the demand of customers who are seeking high-quality wines with less alcohol.

Leaf necrosis induced by the insecticide carbaryl in Vitis rupestris ‘B38’

Carbaryl is an acetylcholine esterase inhibitor-type insecticide used for pest control on grapevine. We repeatedly observed the occurrence of interveinal leaf necrosis following carbaryl spray application in a Vitis rupestris x Vitis riparia F1 hybrid progeny vineyard. Spray applications induced necrosis in this progeny under both Missouri and New York field conditions an approximate one-to-one sensitive-to-insensitive segregation ratio and with 42% concordance. Results of subsequent in vitro experiments established causality between carbaryl treatment and leaf necrosis and confirmed the pattern of segregation observed in the field. We consistently map this phenotype to a major QTL on chromosome 16 of the female parent V. rupestris ‘B38’ regardless of whether we used field or in vitro-generated phenotype data.

Premiers résultats d’une étude des caractéristiques analytiques et sensorielles de vins de Syrah selon leur terroir

A set of Syrah plots covering a wide range of terroirs distributed in the vineyards of the Rhone Valley and the Mediterranean South is examined through their oenological and sensory characteristics. The multidimensional analysis of data leads to the following groupings: (1) A group of unstructured wines with a simple aromatic profile dominated by fruity-floral notes; they come from plots where the ripening conditions have been disturbed by unfavorable climatic conditions, or an excess harvest.

Oligosaccharides in red wines: could their structure and composition be influenced by the grape-growing

Oligosaccharides have only recently been characterized in wine, and the information on composition and content is still limited. In wine, these molecules are mainly natural byproducts of the degradation of grape berry cell wall polysaccharides. Wine oligosaccharides present several physicochemical properties, being one relevant factor linked to the astringency perception of wines (1,2). A terroir can be defined as a grouping of homogeneous environmental units based on the typicality of the products obtained. This notion is particularly associated with wine, being the climate and the soil two of the major elements of terroir concept.

Construction of a 3D vineyard model using very high resolution airborne images

In recent years there has been a growth in interest and number of research studies regarding the application of remote optical and thermal sensing by unmanned aerial vehicle (UAV) in agriculture and viticulture. Many papers report on the use of images to map or estimate the growth and water status of plants, or the heterogeneity of different parcels. Most often, NDVI or other similar indices are used.
