Different strategies were adopted to achieve increases in color stability in Tempranillo wines: (i) addition of maceration enzymes directly to the must, (ii) addition of commercial mannoproteins to...
The chemistry of winemaking and wine development is complex and not fully understood. However, it is clear that oxygen exerts a significant influence during most if not all stages of the process. In
Cork and musty taints are defects currently occurring in wine. This situation applies to all wine-growing areas and is not a new problem. In fact, the issue was raised by Georges Jacquemin in 1903 in
In general, the presence of oxygen is potentially linked to wine alterations. In wine, oxidation depends on the oxygen concentration and on the time of enrichment. In general in enology, a forced o...

The rate of oxidation of SO2 was studied in a wine-model system under aerial oxygen saturation conditions to gain further insight into its mechanism of action in wine. When SO2 was studied alone, n...
Flextank Ptv Ltd. in Australia introduced a new micro-oxygenation tank where gaseous O2 is directly injected into the wine through a sinter. This type of maturation vessel is made of gas permeable ...
The anthocyanin fingerprint of Tempranillo wines made with grapes from two different vineyards of Rioja Alta has been studied by high-performance liquid chroatography during their ageing in oak bar...

The subject of the present work is the study of the influence of pH, temperature, alcoholic content and time on the extraction of some individual ellagic tannins (castalagin, vescalagin, grandinin,...
Previous studies have shown the importance of ethanol and sulfur dioxide production by Saccharomyces cerevisiae on the growth of Oenococcus oeni. Our goal was to examine other interactions between ...
