The influence of native flora on Argentine white terroir cv. Torrontes Riojano

Abstract

The main objective of this paper is to establish considerable differences between wines from three wine areas or terroir, made with cv Torrontes Riojano.

Seventy-one volatile components were used as variables, obtained by means of solid-liquid extraction, quantification by Gas Chromatography with Flame Ionization Detector (FID), and the use of a multivariate statistical model of classification.

We have been able to conclude that the components which differentiate geographical areas in wines come from native flora which is near the vineyards, either owing to cross-pollination, dispersion both of resin and of pollen of the Larrea genus (jarilla), the wind or the solubility of the volatile components found in the soil.

Vintage by vine interactions most strongly influence Pinot noir grape and wine composition in New Zealand

Vine genetics, fruit maturity, region and vineyard are perceived as factors that strongly influence Pinot noir grape and wine composition. Our study aims to understand the relationship between grape (and ultimately wine) composition and the physical appearance and performance characteristics of a vine (i.e. vine ideotype). Our experimental approach controlled these variables by

Bio‐metaethics viticulture proposed by the Giesco. Direct charter with producers. Example of evaluation of training systems

The key points of the current GiESCO charter ‘BIO‐MetaEthics’ are exposed. The new development in cooperation with Giovanni Cargnello is to apply the principles and the content into the practice by establishing a direct contract with producers and other actors of the wine sector. An evaluation sheet is proposed and tested in a new advanced vineyard. For illustrating the methodology of evaluation, the example of the choice of the training systems is detailed on a wide range of situations. 

Advances in the chemistry of rosé winemaking and ageing

The market share of Rosé wine in France has grown from 11 % to 32 % over the last 20 years. Current trends are towards rosé wines of a lighter shade of pink, and where possible, containing a greater concentration in varietal thiols. Grape varieties, the soil on which they are grown, viticultural practices and winemaking technology all impact the polyphenols, color and aromas of rosé wines.

Investigating perceptual interactions of fruity aromas in Bordeaux red wines through addition and reconstitution sensory studies

Fruity aromas, characterized by red and black fruit descriptors, are central to the identity of Bordeaux red wines [1,2]. Despite extensive research focused on identifying and quantifying volatile compounds that contribute to fruity aromas in wine, the mechanisms underlying their interactions and sensory perception remain poorly understood [3].

Geospatial technologies in spatially defined viticulture: case study of a vineyard with Agiorgitiko variety in Koutsi, Nemea, Greece

Geospatial technologies have significant contribution to viticulture, especially in small-scale vineyards, which require precise management. Geospatial data collected by modern technologies, such as Unmanned Aerial Vehicle (UAV) and satellite imagery, can be processed by modern software and easily be stored and transferred to GIS environments, highlighting important information about the health of vine plants, the yield of grapes and the wine, especially in wine-making varieties. The identification of field variability is very important, particularly for the production of high quality wine. Modern geospatial data management technologies are used to achieve an easy and effortless localization of the fields’ variability.
