Protan Chips: a preparation based on proanthocyanidins and oak ellagic tannins, suitably studied to give a better structure and resistance towards oxydations. It is a refining aid particularly suited for wines with a content in anthocyanins not properly balanced by the tannins extracted during maceration. In wines with definite boise notes and with an easy impact, Protan Chips balances the olfactory and gustative sensations, enabling to obtain wines olfactorily very promising, supported by a proper gustative structure, absolutely free from that sensation of “dryness” which often results very penalizing.
