From local classification to regional zoning-the use of a geographic information system (GIS) in Franconia / Germany. Part 1: specific GIS applications in viticulture

Abstract

[English version below]

En vue d’une production économique de qualités des raisins optimales une connaissance des informations les plus différentes est importante. Les nouvelles technologies, telles qu’un SIG permettent de réunir les informations sur le terrain, la nature du sol, le danger d’érosion, le climat, la végétation, l’hydrographie, l’apparition de nuisible et de maladies, etc. Sur la base de cartes topographiques un SIG permet une vaste analyse, une appréciation des rapports complexes ainsi qu’une représentation cartographique. Sur la base de modélisations en trois dimensions du terrain avec le SIG, les ensembles de données saisies ainsi que leur classification au niveau local peuvent être utilisés dans la production de zonages régionaux. Les données du SIG délivrent des informations liées à la protection du sol et de l’eau, la classification climatique, la protection de la vigne, la possibilité d’enherbement, la planification d’irrigation, etc. Les aspects principaux de l’utilisation du SIG en Franconie sont l’enregistrement et l’analyse des données locales, comme les paramètres du sol, le risque d’érosion et les conditions climatique, dans le but d’élaborer des classifications locales des zones à appellation communale et des petits terroirs. A l’aide du SIG, ces classifications locales permettent la création de zonages régionaux, comme par exemple la formation de cartes régionales du risque d’érosion ou la définition de zones de climat local. La modélisation du terrain en trois dimensions permet de déterminer les couloirs d’écoulement de l’air froid et la modélisation des régions soumises au risque de gel, comme les creux et les vallées. Pour cette raison, le SIG en viticulture est un excellent instrument de travail dans la recherche et la consultation viticole ainsi que pour les producteurs de raisins et des domaines viticoles afin d’enregistrer, d’analyser et d’évaluer les influences que des zones régionales déterminées ont à subir. Ainsi le SIG montre aux vignerons leurs surfaces viticoles sous une perspective permettant de mieux analyser le milieu.

For an economically production of optimal grape quality, the knowledge of different types of information is important. New computer software such as a GIS enables the compilation of information on topography, soil, erosion risk, climate, vegetation, infrastructure, and the occurrences of pests and diseases. Based on digital topographie maps, a GIS allows a synoptical analysis of complex correlations and their representation on maps. Based on a three-dimensional terrain modelling with the GIS, recorded data sets and their local classification can be used to establish a regional zoning of viticultural relevant factors as e.g. favourable climatic zones combined with best soil conditions. The GIS data deliver information for fields like soil and water conservation, climatic classification, vine protection, selection of suitable grape varieties and rootstocks, green cover capacity, irrigation planning, yield and quality recording, etc. Main objectives of the GIS application in Franconia are the recording and analysis of local data sets as soil parameters, erosion risk and climatic conditions in vineyard sites. With help of the GIS, these local information enables the creation of a regional zoning of the respective data set, e.g. the generation of regional erosion risk maps or the definition of regional climatic zones. The 3D-terrain modelling allows the determination of flow-off paths of cold air and ‘mapping’ of frost endangered areas like depressions and valleys. Therefore, the viticultural GIS is an excellent aid to researchers and consultants, grape producers and wine growing estates for recording, analysing and assessing viticultural relevant factors in vineyards. This enables a new perspective of vineyards for a better planning of new plantings and also for an improvement of the vineyard management.

Evaluation of the impact of different amelioration techniques on the chemical composition and sensory characteristics of smoke impacted wines

AIM: The increasing incidences of wildfires in wine grape growing regions pose a significant risk. Persistent exposure to smoke can compromise the quality and value of wine grapes and adversely affect wines made from smoke exposed grapes.

The affinity of white wine proteins for bentonite is dependent on wine composition and is directly related to their thermal stability / sensitivity

Bentonite fining is commonly used in oenology to remove all or parts of white wine proteins, which are known to be involved in haze formation. This fining is effective, but has disadvantages: it is not selective, thus molecules responsible for aroma are also removed, it causes substantial volume losses, and finally it generates wastes. Over the last decades, the knowledge of wine proteins has increased: they have been identified, their structures are known, some of them have been crystallized.

Application of satellite-derived vegetation indices for frost damage detection in grapevines

Wine grape production is increasingly vulnerable to freeze damage due to warming climates, milder winters, and unpredictable late spring frosts. Traditional methods for assessing frost damage in grapevines which combine fieldwork and meteorological data, are expensive, time-consuming, and labor-intensive. Remote sensing could offer a rapid, inexpensive way to detect frost damage at a regional scale. Remote sensing approaches were used to assess freeze damage in grapevines by evaluating satellite-derived vegetation indices (VIs) to understand the severity and spatial distribution of damage in several New York vineyards immediately after a frost event (May 17th-18th, 2023). PlanetScope 3m satellite images acquired before and after the freeze were used to map damage and measure changes in VIs for vineyards in the Finger Lakes region.

Impact of press fractioning on current and phenolic compositions of Pinot noir and Pinot meunier wines

In the Champagne’s region, a complete press cycle is a series of pressure increases (squeezes) and decreases (returns). After alcoholic fermentation, the two wines (the “cuvee” and the “tailles”) obtained from grape juice fractions exhibit strong differences for numerous characteristics. Nevertheless, there is no study of the impact of the press cycle, followed after each pressure increase (22-28 steps), on wine colour, current analyses and phenolic composition. So, the aim of this study (vintage 2020) was to investigate the composition changes of Pinot noir and Pinot meunier wines, produced from 22-28 grape juices isolated for each complete pressing cycle.

Texas terroir: gis characterization of the texas high plains ava

The Texas High Plains AVA is one of eight officially recognized wine regions in Texas, established in 1993. Six local wineries, including the second-largest in Texas, are supported by approximately 50 vineyards, which are also major suppliers of grapes to Texas wineries outside the region.
