Tannins from grape pips, above all from red grapes, have a high anti-oxidizing power and, if grapes have reached the ideal ripening stage, they enable to fix the colour, structure the taste, prolong wine longevity. The utilization of Protan Malbec enhances wines’ structure and body, without compro-mising their softness. The treated wines display a full volume, with a persistent and soft honey hint in the aftertaste. The delicate tannin presence, if correctly dosed, makes the wine fresh and clean. Protan Malbec gives wines a high natural anti-oxidizing power, particularly important in those areas and vines with a high pH value, as it ensures the longevity of the varietal organoleptic characteristics.
