Aleatan VINTAGE CST

Appearance

LIQUIDO

Composition

Liquid solution based on ellagic tannin extracted from chestnut wood (Castanea sativa)

stabilized at source with SO2.

General characteristics

Aleatan VINTAGE CST is a liquid tannin that is very active in stabilizing the

color of red wines thanks to a complex of functional activities:

➢ Antioxidant: in the early stages of maceration when the essential oils are not yet extracted

natural tannins from grapes, helps protect the anthocyanins already extracted

from direct oxidation;

➢ Antioxidant: in the case of grapes affected by Botrytis it allows to inactivate the enzymes

laccase (polyphenoloxidase) produced by the fungus;

➢ Pro-oxidant → during racking or on young wines it allows to block oxygen,

triggering the redox mechanism that leads to the formation of the ethanal bridge in

presence of alcohol and condensed tannins.

Applications

Color stabilization in red winemaking.

In the pre-fermentation phase, starting from the pressing, to the filling of the winemaker, to the

racking. Ideal for thermovinification and red wines from sulphite maceration.

Recommended Dosages

Red wines start of maceration 10 – 30 g/100 kg pressed

Red wines racking: 5 – 15 g/hL

Botrytized red grapes: 20-50 g/100 kg crushed

Thermovinified and desulphurized: 5-30 g/hL

Instructions for Use

Dissolve in a small amount of water or must and add to the mass to be treated

homogenizing carefully.
