Protan Peel is a tannin obtained from the skin of unfermented and pressed grapes, processed with a system aimed at extracting proanthocyanidins in a way not to damage them and to keep them reactive. Protan Peel, thanks to the innovative system of water extraction, maintains fresh notes and integrates wines' tannin profile with soft structured notes¡ it has a great affinity towards wines aged in wood. The utilization of Protan Peel during the final refining stages gives wines a longer shelf life and enhances the persistence and the sweetness in the after-taste, effectively covering any possible bitter notes.
