Región Vitivinícola del Vale dos Vinhedos (Brasil): una metodología para la definición de límites geográficos y elaboración de cartas EN escala media

Abstract

Los estudios regionales presentaron en Geografía, como en otras ciencias, en este siglo, varios enfoques. Cualquiera que sea la mirada sobre el espacio, en la base de la temática regional está la concepción de la diferenciación de áreas. Este concepto complejo es utilizado por las diferentes áreas del conocimiento para demostrar que hay espacios con diferentes contenidos. El establecimiento de los límites de partes de espacios, siguiendo una u otra metodología, pone en evidencia su complejidad.
El origen de la vitivinicultura brasileña está relacionado al proceso colonial iniciado en el siglo XVI; su crecimiento a la colonización por inmigrantes italianos de fines del siglo XIX y su desenvolvimiento y calificación a la evolución tecnológica, al mayor conocimiento del viticultor y a la asistencia técnica en las últimas décadas, que resultaron en productos de calidad, que están conquistando mercados exigentes y alcanzando renombre.
Hoy la vitivinicultura está presente en algunos estados brasileños y la atividad tiene importancia en varias regiones pero algunas se destacan más, ya sea por su valor económico o por la identidad social que está asociada, como en la región de la Serra Gaúcha (Mapa 1).
La región vitivinícola del Vale dos Vinhedos es parte de la región vitivinícola de la Serra Gaúcha, ubicada en el sur de Brasil, espacio que tiene la identidad de la cultura de los inmigrantes italianos, en que forma parte el cultivo de la viña, la elaboración y el consumo de vino.
Considerando que en las características de originalidad y tipicidad de la uva y del vino están impregnadas las condiciones geográficas del território donde fueron produzidos, especialmente, aquellas relacionadas al clima y al suelo y considerando que diferentes condiciones del medio están en la base de los diferentes potenciales de calidad que diferencian los productos vitivinícolas, un conjunto de viticultores del Vale dos Vinhedos manifestaron interés en informaciones sobre la región para empezar un proceso de implantación de una Indicación Geográfica para vinos producidos en la región.
Así, el objetivo de la investigación fue delimitar la región y elaborar las cartas de los factores geográficos de la región vitivinícola del Vale dos Vinhedos, en escala media, como subsidio para Indicaciones Geográficas. Para eso fue utilizada la metodología del Sistema de Informaciones Geográficas y de sensoriamiento remoto.

Extreme canopy management for vineyard adaptation to climate change: is it a good idea?

Climate change constitutes an enormous challenge for humankind and for all human activities, viticulture not being an exception. Long-term strategic changes are probably needed the most, but growers also need to deal with short-term changes: summers that are getting progressively warmer, earlier harvest dates and higher pH in musts and wines. In the last 10-15 years, a relevant corpus of research is being developed worldwide in order to evaluate to which extent extreme canopy management operations, aimed at reducing leaf area and, thus, limiting the source to sink ratio, could be useful to delay ripening. Although extreme canopy management can result in relevant delays in harvest dates, longer term studies, as well as detailed analysis of their implications on carbohydrate reserves, bud fertility and future yield are desirable before these practices can be recommended.

Non-Saccharomyces yeast nitrogen consumption and metabolite production during wine fermentation

Over the last decade, the use of non-Saccharomyces yeasts in the winemaking process has been re-assessed and accepted by winemakers. These yeasts can be used to achieve specific objectives such as lowering the ethanol content, preventing wine spoilage and increasing the production of specific aroma compounds. Since these species are unable to complete alcoholic fermentation, strategies of co- and sequential inoculation of non-Saccharomyces and Saccharomyces cerevisiae have been developed. However, when mixed starter cultures are used, several parameters (e.g. strain yeast, inoculation timing and nutrient competitions) impact the growth of the individual yeasts, the fermentation kinetics and the metabolites/aroma production. In particular, competition for nitrogen compounds could have a major impact, potentially leading to sluggish fermentation when the yeast assimilable nitrogen (YAN) availability is low. Moreover, many aroma compounds produced by the yeasts are directly produced and influenced by nitrogen metabolism such as higher alcohols, acetate esters and ethyl esters which participate in the organoleptic complexity of wine.

Contribution du potentiel glycosidique à l’arôme des vins de Grenache noir et Syrah en Vallée du Rhône

Grenache Noir and Syrah are the predominant grape varieties in the French Rhone valley vineyard, and produce wines with well differentiated aromatic notes. This study aimed at investigating the contribution of glycoconjugated precursors to these aromatic specificities, through their analytical profiles and the sensory influence of the odorant compounds they release during wine aging. The aglycones released by enzymatic hydrolysis of glycosidic extracts

Does Dekkera/Brettanomyces wine spoilage raise the risk of biogenic amines intake? A screening in Portuguese red wines

Wine quality and safety are the main concerns of consumers and health agencies. Biogenic amines and polyamines, depending on their concentration and on individuals, in wine can constitute a potential public health concern due to their physiological and toxicological effects

Elevational range shifts of mountain vineyards: Recent dynamics in response to a warming climate

Increasing temperatures worldwide are expected to cause a change in spatial distribution of plant species along elevational gradients and there are already observable shifts to higher elevations as a consequence of climate change for many species. Not only naturally growing plants, but also agricultural cultivations are subject to the effects of climate change, as the type of cultivation and the economic viability depends largely on the prevailing climatic conditions. A shift to higher elevations therefore represents a viable adaptation strategy to climate change, as higher elevations are characterized by lower temperatures. This is especially important in the case of viticulture because a certain wine-style can only be achieved under very specific climatic conditions. Although there are several studies investigating climatic suitability within winegrowing regions or longitudinal shifts of winegrowing areas, little is known about how fast vineyards move to higher elevations, which may represent a viable strategy for winegrowers to maintain growing conditions and thus wine-style, despite the effects of climate change. We therefore investigated the change in the spatial distribution of vineyards along an elevational gradient over the past 20 years in the mountainous wine-growing region of Alto Adige (Italy). A dataset containing information about location and planting year of more than 26000 vineyard parcels and 30 varieties was used to perform this analysis. Preliminary results suggest that there has been a shift to higher elevations for vineyards in general (from formerly 700m to currently 850 m a.s.l., with extreme sites reaching 1200 m a.s.l.), but also that this development has not been uniform across different varieties and products (i.e. vitis vinifera vs hybrid varieties and still vssparkling wines). This is important for climate change adaptation as well as for rural development. Mountain areas, especially at mid to high elevations, are often characterized by severe land abandonment which can be avoided to some degree if economically viable and sustainable land management strategies are available.
