Evaluation of state of vineyards and characterization of vineyard sites of the integrated area of Tokaj Kereskedőház ltd. in Tokaj region

Abstract

The Tokaj Kereskedőház Ltd. is the only state owned winery in Hungary. The company is integrating grapes for wine production from 1100 hectares of vineyard, which consist of 3500 parcels with average size of 0,3 hectares, owned by about 500 families of the region. The vineyards are unevenly spread in total 27 village of Tokaj region. 

The aim of our study was to determine the state of vineyards of each single parcel of the integrated area, and the characterization of the ecology of the vineyard sites. Based on the information collected a site-specific vineyard design and cultural practice could be achieved on the given territory. 

The state of vineyards, concerning variety, training system, trellis system, row and vine spacing, row orientation, and production characteristic was determined by visual inspection of every single parcel. Airborne hyperspectral imagery was taken, covering the whole Tokaj Wine Region. High-resolution spectral-spatial geodata were captured and analyzed to focus on variety determination, evaluate biophysical properties (NDVI, LAI, Red Edge Position), canopy continuity, structure and identify row anomalies. 

The characterization of vineyards sites was accomplished based on large-scale determination of topography, soil and meso- and macroclimate variables covering the total 11000 hectares planted and potential vineyard land area of Tokaj Region. According to soil survey Digital Optimalized Soil Related Maps and Information Method was taken to produce the proper thematic data layers in 25 m spatial resolution. Results of surveys are analyzed and managed in a geographical information system designed for the project. 

The methods applied during the data collection and analysis will be detailed, while the preliminary results of the state of vineyard and the characterization of vineyard sites will be demonstrated.

Study of cross-modal interactions through sensory and chemical characteristics of italian red wines

This work aimed at investigating red wine olfactory–oral cross-modal interactions, and at testing their impact on the correlations between sensory and chemical variables. Seventy-four Italian red whole wines (WWs) from 10 varieties, and corresponding deodorized wines (DWs), were evaluated by sensory descriptive assessment.

Study of fungal and bacterial laccases for the reduction of ochratoxin A content in model wine

Ochratoxin A (OTA) is a mycotoxin produced by several filamentous fungi infecting grape bunches (Penicillium and Aspergillus spp.), this toxin pass to must when grapes are crushed and later it is found in wine. Following the evaluations of the toxicity of OTA, European Commission Regulations have been promulgated introducing upper limits for OTA concentrations in various commodities (cereals, cereal products, dried vine fruit, coffee, wine, grape juice, baby foods and dietary foods for special medical purposes).

Investigating water stress-related seasonal and spatial patterns and the possible links with juice and wine compositional parameters

The mapping of spatial variability in vineyards offers the potential to implement zonal management strategies with the aim to optimize economic benefits and increase sustainability by managing natural resources, such as water used for irrigation, more optimally. This study characterized the (natural) variability in plant water status in a commercial Cabernet Sauvignon block, using remote sensing techniques, and identified the impact of this variability on the yield, and juice and wine composition. From the field data collected over two growing seasons, we demonstrated that remote sensing techniques are a practical and powerful tool for mapping spatial variability within vineyard blocks.
