Composition :
- Chestnut tannins : 75 %
- Pure oak tannin : 25 %
Properties :
Addition of a small amount of tannin to the base wine is very often recommended as this :
- improves the action of the fining agent.
- gives a more elastic deposit, and is an essential complement to the
additives for tirage bottling in new format – Colle 2, Argitirage
However, the tannins added must meet certain specific requirements :
- provide polymerized tannins which contribute essentially to the
fining.
- not leave astringent or bitter polyphenolic compounds in the wine.
Boltane P Export has been formulated according to these requirements.
