Mapping terroirs at the reconnaissance level, by matching soil, geology, morphology, land cover and climate databases with viticultural and oenological results from experimental vineyards

Abstract

This work was aimed at setting up a methodology to define and map the «Unités Terroir de Reconnaissance» (UTR), combining environmental information stored in a Soil Information System with experimental data coming from benchmark vineyards of Sangiovese vine.

A Soil Information System stored geography (reference scale 1:100,000) and attributes of i) land cover, ii) lithology, iii) morphology, iv) soil typologies, v) soil properties, vi) soil geography, vii) long term average Winkler bioclimatic index and average rainfall, and viii) appellation of origin area, of the whole Province of Siena. Soil functional properties were selected and classified after a statistical analysis of the relationships with the viticultural and oenological results obtained in 69 vineyards over a time span of 2-5 years. All the vineyards of the province were grouped in terms of lithology, morphology, and soil functional properties, so as to create homogeneous UTR. The result was that the whole province was characterized by 363 UTR, which covered a total of 16,650 ha, each UTR having a size ranging from 2 to 474 ha. The GIS map highlighted and explained the environmental diversity of viticultural areas of the province, providing information about peculiarities, constraints and potentialities of each UTR.

Enhancing grapevine transformation and regeneration: A novel approach using developmental regulators and BeYDV-mediated expression

Grapevine (Vitis vinifera L.) is a challenging plant species to transform and regenerate due to its complex genome and biological characteristics. This limits the development of cisgenic and gene-edited varieties. One hurdle is selecting the best starting tissue for the transformation process, much like isolating suitable tissue for protoplasts. One promising method involves delivering crispr/cas components to protoplasts isolated from embryogenic calli, which are then induced to regenerate.

Can wine composition predict quality? A metabolomics approach to assessing Pinot noir wine quality as rated by experts

The perception of wine quality is determined by the assessment of multiple sensory stimuli, including aroma, taste, mouthfeel and visual aspects. With so many different parameters contributing to the overall perception of wine quality, it is important to consider the contribution of all metabolites in a wine when attempting to relate composition to quality.

RED WINE AGING THROUGH 1H-NMR METABOLOMICS

Premium red wines are often aged in oak barrel. This widespread winemaking process is used, among others, to provide roundness and complexity to the wine. The study of wine evolution during barrel aging is crucial to better ensure control of wine quality.
¹H-NMR has already been proved to be an efficient tool to monitor winemaking process [1]. Indeed, it is a non-destructive technique, it requires a small amount of sample and a short time of analysis, yet it provides clues about several chemical families.

Effets des pratiques agro-viticoles sur l’activité biologique et la matière organique des sols : exemples en Champagne et en Bourgogne

The notion of terroir covers multiple components, from geology, pedology, geomorphology and climatology (Doledec, 1995), to aspects that are less well identified but which also intervene in the “typicality” of wines. This justifies the “zoning” approach (Moncomble and Panigaï, 1990) to define homogeneous areas, under the same agro-viticultural management and also identified at the product level (Morlat and Asselin, 1992).
