  • An electrochemical method for real time measurement of polyphenols during winemaking
    By Christine Pascal, Nelly Champeau, Jean Baptiste Diéval, Stéphane Vidal; Vinventions, Enology team, 7 avenue Yves Cazeaux, 30230 Rodilhan, France
    Polyphenols are known to play a major role in must oxidation as well as in wine aging and oxidation. However, they are difficult to measure in the cellar due to lack of adequate technology. Therefo...

Microbiological and agronomic study of vineyard soils

Vineyard management and a number of biotic and abiotic factors shape vineyard soil microbiota.

The objective of this study was to investigate the influence of different vineyard management and land use systems, which included: a) conventional management with tillage, b) grass cover between grapevine rows, and c) grapevines planted in rows running down the slope with inter row tillage, on the culture-dependent microbiota associated with the vineyard soils and some edaphic parameters of the studied soils.

From this study it can be concluded that the vineyard soil is a yeast reservoir that contains yeast populations above 104 CFU per g of dry soil, and that given a geographic location and a Vitis vinifera cultivar, the vineyard management strategy plays a pivotal role in the soil microbial composition.

Article based on the poster presented at the at the 12th edition of Enoforum (Vicenza, Italy, May 21-23, 2019).
