Topographic modeling with GIS at Serra Gaúcha, Brazil: elements to study viticultural terroir

Abstract

Brazil is historically known at the international wine market as an importer, eventhough in the last decades there was an increase in quantity and quality of the internal production. Nowadays, about 40% of fine wines comsuption of the country are national ones. The main production region is called Serra Gaúcha, where the natural conditions are heterogeneous and viticulture is develloped in small properties, mainly done by the owners family. With the strong competition in internal and external market, there is a need to search distinct products in characteristic and typicality. In this context, the concept of terroir is important to drive an to match the grape variety and the cultural practices to the natural potential of each place. This work aim s to study the topographical components of the terroir at Serra Gaúcha using GIS. The study was based on a digital terrain model derived from 20 topographical map sheets in scale 1:50,000. The topographical variables analized were elevation, slope and aspect. Each variable was scores according to its suitability and integrated later on to generate topographical suitability map. The results show that 66% of the area has medium and 9% has high topographical suitability for grapes growth.

Application of grape pomace and stem extracts on Vitis vinifera L. cv. Monastrell: Increased stilbene content of grapes and wines

Pomace and grape stems are the main solid organic waste from winery industries, resulting from the pressing and/or fermentation processes it is generated in large amounts in many parts of the world

Evolution of the metabolic profile of grapes in a context of climate change

In the current context of global climate change, anticipating the evolution of the oenological potential of emblematic grape varieties of regions such as Burgundy and Champagne is a guarantee of the sustainability of a sector which has considerable economic weight. however, if various models of climate change cast doubt on the sustainability of these grape varieties in these regions, appellation decrees, as well as consumer expectations, do not allow or consider the use of alternative grape varieties. In addition, control/compensation methods such as irrigation are also not permitted.

INFLUENCE OF THE NITROGEN / LIPIDS RATIO OF MUSTS ON THE REVELATION OF AROMATIC COMPOUNDS IN SAUVIGNON BLANC WINE

Production of volatile compounds by yeast is known to be modulated by must nitrogen. Nevertheless, various parameter of must quality have an impact on yeast fermentation. In this study we propose to evaluate the impact of nitrogen / lipids balance on a Sauvignon Blanc grape juice (Val de Loire).
Must was prepared from the same grapes at pilot scale. Three modalities were carried out: direct pressing, direct pressing with a pre-fermentation cold stabulation and pellicular maceration before pressing.
