Tannins are relatively large phenolic polymers that derive from the polymerisation reaction of phenolic monomers.
Tannins are relatively large phenolic polymers that derive from the polymerisation reaction of phenolic monomers. Their reaction with glycoproteins present in saliva determines the sensory sensation of astringency. They are present in all the solid parts of the grape (skins, seeds and stalks), flow into the must during the maceration phase and end up in the wine.
The CDR WineLab® method allows to monitor the concentration of tannins in wine in order to monitor the evolution of these both during alcoholic fermentation and during the micro-oxygenation phase.
