Satellite imagery : a tool for large scale vineyard management


Remote sensing, using Near Infra Red wavelength, can characterize within-vineyard variability using vegetation index. Between 2007 and 2009, a study was led on the vineyards of a cooperative winery, in Fitou area (France) aiming at characterizing vineyard oenological potential. A vegetation index, green leaf cover, developed on crops (wheat, rice, corn…) was implemented on vineyards.
In a first stage, it was proved that the use of 2m/pixel resolution gave the same precision of field variability mapping than a 0,50 m/pixel resolution, which made possible the use of satellite datas, covering a 57 600 or 302 500 ha zone (respectively 24 km x 24 km or 55 km x 55km). Then a heterogeneity index, adapted from Pringle’s opportunity could be calculated for each vine, which can be characterized by an average leaf cover index (a “vigor” index), and an heterogeneity index. Detection of high levels of bare soil in a vine can also be identified automatically.
Based on these indexes, each vine can be characterized and gathered with other vines with the same characteristics (homogeneous vines with either low or high vigour, heterogeneous vines, abnormal vines with excessive bare soil….). According to such a classification realized just before veraison, the winery could select bins corresponding to each quality of vines. Separate vinifications proved sensorial differences on wines: homogeneous vines would give wines with intense jammy and spicy flavours, interesting body in mouth, and smooth tannins, whereas heterogeneous vines tended to produce wines with more red fruit and grassy aromas, and coarser tannins. These differences are consistent from year to year. This selection method is used on 50 % of carignan vines by the winery, which cannot be visited by its technical staff.

Use of the soils information system for detailed vineyard soil surveys and as a component of precision viticulture

Vineyard soil surveys can be costly and time consuming. The Soils Information System (SIS) provides a set of tools to do a quick evaluation of soil physical properties in the vineyard. First, a system equipped with GPS and EM38 equipment, provides a very precise DEM and a soil electrical conductivity map. Specific sampling points are located for a tractor-mounted geotechnical probe to make soil physical measurements.

Reconnaissance des vins de terroir par les consommateurs

Approaching the notion of terroir wines at the level of consumption poses a problem due to the absence of a regulatory definition of the term terroir, which is not taken up either at Community level or at national level (the Consumer Code in particular does not define not the land). However, whatever definition is adopted for the terroir, we can retain at the consumer level an identification of the terroir through the different geographical mentions appearing on the labels or on the shelves of the wine shelf.

Monitoring of Sangiovese red wine chemical and sensory parameters along one-year aging in different tank materials and glass bottle

The aim of this study was to test how different tank materials could affect the chemical composition and the sensory profile of a red wine during an entire year of aging. For this scope, a single varietal Sangiovese wine was aged, after completing its malolactic fermentation, by using tanks made by different materials. Six thesis were involved in the aging experiment, in particular: stainless

Creativini: an augmented reality card game to promote the learning of the reasoning process of a technical management route for making wine 

Nowadays, the entire viticultural and enological process is wisely thought out according to the style of wine to be produced and the local climatic conditions. Acquiring the approach of a technical management route specific for wine production remains a complex learning process for students. To enhance such learning, The Ecole d’Ingénieurs de PURPAN (PURPAN), an engineering school located in Toulouse southwest France, has recently developed Creativini, a collaborative card game in English made of 150 cards spread into 14 batches. Students in groups of 3 to 6 must design a technical production route, from plant material to bottling.
