Smartan® SG

Highly soluble, soft ellagic tannins in a granular blend obtained from French oak.

If added from the start of vinification, Smartan® SG helps to maintain the wine’s structure, forming a chemical complex with unkind organoleptic notes. It is used to manage reduction, reducing the “vegetable” notes coming from extracted tannins and to give harmony and oxidative resistance. It is delicate if applied during refinement and finishing of white wines.

When used on red wines from racking onward, Smartan® SG gently contributes to the structuration phase of the polyphenolic component at the moderately aerobic phase, and during refinement to provide greater stability to wines. It has a moderate clarifying action.

A special treatment called “instantising” makes Smartan® SG readily soluble in water while respecting its valuable organoleptic qualities and specific reactivity (SG Patent).


Smartan® SG is suited for joint use with micro-oxygenation.
