Beyond copper. Six alternative remediation strategies for reduction defect in wine: results and prospects
Diego SÁNCHEZ-GIMENO | LAAE, Universidad de Zaragoza, Spain
When the reduction defect is perceived in wine during fermentation, there is a tendency to perform certain procedures such as aeration or oxygenation or, if the treatment persists, micro-oxygenation or copper treatment. But in reality these treatments, which are very effective in the short/medium term, do nothing more than slow down the appearance of this defect, they do not eliminate it. In other words, the responsible compounds will reappear sooner or later.
In this presentation, Diego Sanchez Gimeno explains exactly what the reduction defect is and what are the balances and factors that determine its appearance. He then presents the interesting research work carried out by the Laboratory of Aroma Analysis and Oenology of Zaragoza in which six possible alternative treatments to copper treatment were evaluated.

Wine is fundamentally a high-intervention product, and along all stages from harvest to bottling it's our job to guarantee safety and quality, but it's also up to us to research, experiment, and ad...
Producing a wine according to our oenological objective, wanting to express the variety, but adapting practices according to the sanitary status of the grapes, is continuous experimentation. We aga...
Phenolic composition of grapes has an important impact on the final intrinsic quality of (red) wines. Wine taste, mouthfeel and colour are driven principally by phenolic compounds present in grapes...
For the production of quality sparkling wines, it is important to ensure the separation of the correct phenolic profiles of must fractions. Find out how UV-Visible spectroscopy, together with chemo...
Chemical, biochemical and physiological factors influence the composition of the retronasal aroma during wine consumption, but not only tannins influence mouthfeel: anthocyanins do too. New methods...
What's the importance of varietal thiols, esters and glycerol content from an organoleptic quality point of view? How do volatile compounds evolve during wine aging and storage conditions? Are ther...
