Robur Red 65

Purified, from wood and from shrub leaves extracted tannins, particularly aromatic, with marked and elegant red fruit and cherry hints, rich in tannic acid. Innovative low-temperature-process, to maintain unaltered the organoleptic characteristics and the reactivity of the molecule, retaining a particularly high antioxidant power.

Studied for addition at final bottling phase, with dual action: 

• Organoleptic: fixes aromas and protects against oxidation, increasing persistence, complexity and intensity (it particularly increases the fruity freshness and the cherry and morello notes) balancing gustative asperities.
• Chemical: it stabilizes the combined SO2 (SO2-acetaldehyde-tannin bridge), protects free SO2 (up to 24-36 months after bottling); it adjusts the oxidant action of copper.
