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.

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

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...

A novel electrochemical approach for rapid analysis of white grapes polyphenols and monitoring of pre-fermentative operations

M. UGLIANO, J. WIRTH, S. BÉGRAND, J. B. DIÉVAL, C. PASCAL, S. VIDAL; Università degli Studi di Verona - Vinventions, Francia

The ability to rapidly quantify and characterize phenolic composition of grapes and must is critical in the optimization of winemaking practices. In the case of white wine production, measurement o...

About the Role of the Bottleneck/Cork Interface on Oxygen Transfer

Aurélie Lagorce-Tachon et al. J. Agric. Food Chem., 2016, 64 (35), pp 6672–6675

The transfer of oxygen through a corked bottleneck was investigated using a manometric technique. First, the effect of cork compression on oxygen transfer was evaluated without considering the glas...

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...
