Microbiological and agronomic study of vineyard soils

Microbiological and agronomic study of vineyard soils

Ugarte, J., Tenorio, C. and Ruiz-Larrea, F.; ICVV, University of La Rioja, Spain.

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.

A new device for stabilisation of white wines throughout a continous flow system

Parpinello, G.P., Ricci, A., Serantoni, M., Balducci, A., Ragni, L., Versari, A.; University of Bologna, Italy

Proteins occurring in wine originate from several sources during the winemaking process. Protein content in wines ranges from traces up to hundreds of mg/L, and may cause physical instability in wh...

An electrochemical method for real time measurement of polyphenols during winemaking

By Christine Pascal, Nelly Champeau, Jean Baptiste Diéval, Stéphane Vidal; Vinventions, Enology team, 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...
