Geologic and geomorphologic features applied for identification of wine terroir units by digital image processing, spectroradiometric and GIS techniques in Encruzilhada do Sul, RS, Brazil

Abstract

Results in the characterization of a new wine terroir unit in south Brazil are reported. Presently, several areas in Brazil are being studied, in an effort to define new wine terroirs and improve the quality of Brazilian wines. This paper reports what is being done, by Embrapa (Brazilian Agricultural Research Corporation) and its partners Remote Sensing and Meteorological Research Center (CEPSRM/UFRGS) and Brazilian Geological Survey (CPRM), in the Encruzilhada do Sul region, at Rio Grande do Sul State, that is part of the Serra do Sudeste viticultural region. Satellite images from several sources (SRTM, ASTER, ALOS) were used, together with field data (rock samples). Digital elevation models were built and used to define areas with slopes and solar expositions adequate to vine growing, with altitudes above 350 m. Spectroradiometry of rock samples was performed, to identify several minerals (montmorilonite, illite, pyrophilite and kaolinite). Geologic maps were used to locate rock types to collected in field trips; those rocks had their spectral response extracted from radiometry, and fitted to the six bands of ASTER SWIR subsystem, resulting in a map of the distribution of these rocks in some areas of interest. Two wineries were more closely studied. The first area produces wine from 35 hectares of Cabernet Sauvignon, Merlot, Nebbiolo, Pinot Noir and Chardonnay. The other winery has 61 hectares and produces Pinot Noir and Chardonnay grapes for sparkling wines. The study concludes that the use of remote sensing resources and associated geotechnologies are effective to terroir studies.

Terroir Hesse – Soil determines wine style

The project “Terroir Hesse” works out the main type and characteristics of soil-based terroirs and the resulting wine styles for the hessian wine-growing regions Rheingau and Hessian Bergstrasse.

Effects of wine versus de-alcoholised wine on the microbiota-gut-brain axis in a tau-pathology murine model of Alzheimer’s disease

Alzheimer’s Disease (AD) is the most common disorder associated with cognitive impairment and the main cause of dementia globally. Multiple evidence in the last decade suggest that the gut microbiome plays an important role in the pathogenesis and progression of AD via the microbiota-gut-brain axis, a network wherein microbiome and the central nervous system crosstalk via endocrine, immune, neural, and microbial metabolites signalling pathways.

Heat requirements for grapevine varieties is essential information to adapt plant material in a changing climate

Precocity for fruit ripening is a genetically determined characteristic that is highly variable from one cultivar to another. In traditional wine-growing regions of Europe, growers have used this property to adapt the vines to local climatic conditions in order to maximize terroir expression

Zonage et caractérisation des terroirs de l’AOC Côtes-du-Rhône: exemple du bassin de Nyons-Valreas

The southern Côtes-du-Rhône vineyard shows a significant variety of ecological facets over the Lower Rhone Valley. Intending to characterize such a variety of “terroir “called vineyard situations, a spatial approach based on identification of soil landscapes has been initiated.

The role of phytoplasma effector interaction with phosphoglucomutase in the pathogenicity of ‘Candidatus Phytoplasma solani’ in grapevine 

Bois noir is the most widespread phytoplasma grapevine disease in Europe. It is associated with ‘Candidatus Phytoplasma solani’. In symptomatic grapevines cv. ‘Zweigelt’ infected with ‘Ca. P. solani’ compared with uninfected grapevines, metabolic pathways associated with phosphorylated sugar production were induced both at the transcriptional level and at the level of activity of the corresponding enzymes (Dermastia et al., 2021, Int. J. Mol. Sci. 22: 3531). In particular, the expression of gene coding for phosphoglucoisomerase was upregulated, resulting in increased phosphoglucoisomerase enzyme activity.
