Characterization of aromatic profiles in Brazilian tropical wines determined by gas chromatography and multivariate statistical analysis
Tropical wines have been produced in Thailand, India, Venezuela and mainly in Northeastern Brazil. In Brazil, this activity started twenty-five years ago and has been studied only in the last years. In this Brazilian Area, between 8-9° parallel of the South Hemisphere, it is possible to have two or three harvests per year due to the high temperatures (annual average temperature of 26 °C), high luminosity and use of irrigation.
Sensory profiles of tropical wines produced in the São Francisco River Valley (Northeast Brazil)
Given the lack of available information on the subject, this study aims to characterize and evaluate the sensory stability of the experimental wines made from Vitis Vinifera – Syrah, Petit Verdot, Tempranillo, Sauvignon Blanc, Verdejo and Viognier – grown in the region of Vale de São Francisco in the northeast of Brazil, where the climate is tropical and semi-arid.
Photosynthetically active radiation levels in a Syrah vineyard in a Brazilian tropical semiarid area: preliminary results
This work aimed to determine the photosynthetically active radiation (PAR) incidence at the berry level at east (E) and west
(W) direction in a Syrah vineyard growing in a tropical semiarid area of Brazil.
Effects of leaf removal and shoot trimming on physiological and agronomic characteristics of Syrah grapevine in Northeast Brazil: preliminary results
The São Francisco Valley, Northeast Brazil, is one of the most important wine regions with tropical conditions in the world. It is located between parallels 8 and 10°S, with an average annual temperature of 26.5 ºC and 3,000 hours of sunshine per year.
Cabernet-Sauvignon in tropical semi-arid climate (Pernambuco–Brasil) – adaptation of some clones and their affinity to different rootstocks
The variety Cabernet Sauvignon has revealed in the São Francisco Valley (9º02′ S; 40º11′ W) a high potential of quality, but with some limitations on its adaptation to this “terroir”. The rootstocks with effective affinity are yet unknown and the material with many virus infections makes difficult its culture, particularly in terms of yield, which generally is very low.
Quality potential of “new-old” white winegrape genotypes from Daunia (Northern Apulia region): back to the future?
In the Northern province of the Apulia Region (Foggia, syn. Daunia, Italy), several old white wine-grape genotypes were found in the area called “Alto Tavoliere”.
Integrative strategies for sustainable viticulture and terroir valorisation
Sustainable viticulture and the valorisation of terroir require an integrated approach that is largely based on judiciously applied conventional viticulture and may include elements of what are additionally used in organic or biodynamic farming.
Application of new research approaches in the evaluation of viticultural potential of different terroirs (preliminary results)
A combined study has been started in 2010 in 4 different growing sites of the Eger wine district of Hungary. The aim of the investigation was to describe viticultural potential of different terroirs using new research tools: i.e. Multiplex Research®, Berry Texture analyzer, hyperspectral camera.
Delineation of potential viticulture areas in south-western Poland
The paper addresses the issue to recognize spatio-temporal variability of thermal conditions in SW Poland to delineate the areas suitable for wine growing in the regional scale.
Models of architectures adapted to a sustainable viticulture – interest and development of the foldable lyre
A definition of sustainable Viticulture is proposed. On that basis, the optimal characteristics of the canopy architecture are chosen, such as an high Exposed Leaf Area which can be eventually flexible at the end of the season in function of the drought,
Studying soil quality is essential to evaluate the sustainability of a vineyard
Generally, viticulture was based on practices using synthetic weed killers, fertilizers and massive utilization of pesticides.
Total grass cover in vineyards: An innovating and promising soil management alternative to reduce the use of herbicides
In order to reduce the use of herbicides, total grass cover (between and under the rows of vine) could be an interesting solution if the competition for nitrogen and water supply is controlled.
Establishing baselines for carbon sequestration and soil sustainability of vineyard lands in Northern China
Baselines for both soil carbon sequestration and cropping system sustainability were established for two sites in northeast China which may be useful in developing future verification strategies for carbon capture and GHG emission reduction.
The management of intercrops in vineyards should be adaptive to buffer the effects of climate variability on the grapevine performances
In viticulture as in other crop productions, adaptation to climate fluctuations is needed to mitigate their possible impacts on productivity and on the quality of products.
Pluriennal trials for the control of grapevine downy mildew with natural products
Downy mildew, caused by Plasmopara viticola, is one of the most dangerous grapevine diseases. In organic vineyards, downy mildew is mainly controlled with copper compounds.
Nero Di Troia, Susumaniello, and Uvalino: Italian autochthonous wine grape varieties with high contents in stilbene and flavonoid compounds
During the 2009 vintage a survey was conducted on flavonoid and stilbene content of three black wine grape varieties such as Susumaniello, Uvalino and a specific biotype of Nero di Troia with small berries.
Antioxidant activities of grape seeds from different cultivars and clones of central Italy
Recent investigations have pointed out that, among the fruits, grapes and all grape products represent a source of dietary flavonoids, considered as antioxidant nutritive supplement.
Effects of canopy height and irrigation on Tempranillo grapevines (Vitis vinifera L.) – water relations, vine performance and fruit composition
The effects of combined treatments of canopy height and irrigation on yield and fruit quality were studied during two seasons, in a Tempranillo vineyard trained to a bilateral cordon N- S oriented.
Effect of the terroir on the nutraceutical proprieties in Vitis vinifera L. cv Dolcetto
Phenols in foods have gained much attention, owing to their antioxidant activities and their possible beneficial implications to human health, a consequence of their proven biological activity in the prevention of cancer and cardiovascular diseases.
