Some red wines develop a “bouquet” during ageing. This complex aroma is linked to quality by wine tasters. The presence of dimethylsulfide (DMS) in those wines is implicated in the expression of “b...
This research aims at developing an efficient and food grade method for the extraction of yeast MPs from commercial wine lees, and to test the obtained extracts as wine stabilisers, foaming agents,...

The aim of this work was to study winemaking alternatives that will optimize the quality of the Tannat wines, taking advantage of the grape's oenological potential.
Francisco Carrau; Faculty of Chemistry, University of the Republic, Montevideo (Uruguay)
His research is focused on the development of sustainable viticulture practices and “low-input winemaking” strategies for increased quality and wine differentiation; yeast fermentation technology r...

This study evaluated the effect of a wide range of environmentally friendly products applied in the vineyard on grape yeast ecology at harvest, as well as during spontaneous and inoculated fermenta...
The objective of this study is to determine if the application of US to grapes of different maturity level/sanitary status leads to the same positive outcome as regards chromatic, phenolic and arom...
