New-Cel is an organic polymer soluble in water, studied to give wines the tartaric stabilization during time. The stabilization of tartaric precipitations represents one of the most important problems of oenology: the treatment has a high cost and in some cases the result is not sure; common technologies have often an impact against the colour and the other organoleptic characteristics. The utilization of New-Cel at low doses enables to protect acidity and to obtain a perfect stability during time.
