Available from our represented firm Unitan, COLATAN GT-4© is a 100% natural product approved for oenology, based on vegetable tannins and obtained from the Quebracho Colorado tree, growing solely in northern Argentina.
Thanks to its unique characteristics COLATAN GT-4© gives wines particular features that other tannins are not able to show, such as:
— Colour: COLATAN GT-4© is able to enhance and stabilize red colour, while reducing browning tendency.
— Astringency: the product has been designed to give wines the typical astringency coming from an oak barrel ageing (boisage).
— Clarification: COLATAN GT-4© promotes hte precipitation of soluble proteins, thus improving clarification and allowing to obtain both red and white wines perfectly clear and with a high quality standard.
— Reactivity with sulphur compounds: COLATAN GT-4© is an excellent aid for absorption of sulphur dioxide and thiols/mercaptans arising from fermentation.
Products available either in powder or granular form.
Packaging: 25 kg bags on 1000 kg pallets (net weight)
