Contribution of soil for tipifiyng wines in four geographical indications at Serra Gaúcha, Brazil

Abstract

Brazil has a recent history on geographical indications and product regulation for high quality wines. The first geographic indication implemented was the Vale dos Vinhedos Indication of Procedence (IP), within the wine production zone named Serra Gaúcha, northeast of State Rio Grande do Sul. During the last decade, the Vale dos Vinhedos ascended to the category of Denomination of Origin (DO) and three new IPs were delimited in the same region: Pinto Bandeira, Altos Montes and Monte Belo. It is known that production of high quality wines depends on the interaction of environmental factors and human activities. At local scale, soil plays important role since several factors affecting grape and wine quality are related to soil properties. The objective of this study was to evaluate potential contributions of soil to differentiate between wines produced in each of the four geographic indications at Serra Gaúcha.

Material used included a digitized soil map in scale 1:50.000 of Serra Gaúcha and digital georeferenced boundaries of the geographic indications. Spatial analysis was done on ArcGIS software. A total of 23 soil mapping units were found. Results showed that both the DO Vale dos Vinhedos (15 mapping units) and IP Pinto Bandeira (13 mapping units) have a relative predominance of Inceptisols, with low natural fertility and low organic matter content. The IP Monte Belo (9 mapping units) presents near 50% of Ultisols, with low natural fertility and medium to high levels of organic matter. In the IP Altos Montes (11 mapping units) most soils are Inceptisols with low natural fertility and low organic matter content, as well as Oxisols with low natural fertility and medium level of organic matter. Due to the observed spatial variability, soil information can help to tipify and differentiate wines produced in each of the four geographical indications at Serra Gaúcha.

Monitoring of grapevine stem potentials with an embedded microtensiometer

Vine water status is a crucial determinant of vine growth, productivity, fruit composition and terroir or wine style; therefore, regulating water stress is of great importance. Since vine water status depends on both soil moisture and aerial environment and is very temporally dynamic, direct measurement of vine water potential is highly preferable. Current methods only provide limited data. To regulate vine water status it is critical to monitor vine water status to be able to: (1) measure vine water status to predict the effect of water stress on the overall vineyard performance and fruit quality and optimize harvest management and wine-making (2) properly regulate the water status to impose for a desired fruit quality or style (3) determine if water management has reached the desired stress level.

Organoleptic and analytical impacts of the color of glass of the bottles on Chasselas wine

This study was performed on Chasselas wine to assess the impact of exposure to wine light according to several glass color of bottles. The aim was to highlight any differences whether from an organoleptic or analytical point of view depending on the color. For this, four different shades were compared, dead leaf, green, cinnamon and transparent. A control, not treated with light, was also included in the study…

Behaviour of two training systems for mechanical pruning combined with different nitrogen fertilizations on cv. Colombard

Today winegrowers involved in mechanical winter pruning are applying this viticultural technique on two main training systems, the free cordon, appearing to be the more efficient, and the trellised vertical shoot positioning (VSP) system. The main reasons for maintaining the trellis are generally due to common habits in vineyard management, risk of wind damage for the shoots, or risk of decrease in photosynthesis potential. The aim of the study was to assess the effects of the two training systems on vine. In addition, different nitrogen fertilization levels were applied on the two systems to evaluate the best combination to achieve yield and grape quality.
