– Tannage of hides –
The so-called “vegetable” is the material comes from the tree,
which we call “tannin”. It is brown-yellow colour, very astringent.
After extraction into a tannin powder can be use for making leather,
the very ancient and traditional tanning method.
When we taste the red wine, something we feel it has “strong tannin”,
actually they are the same materials.
