Method of clarification and stabilization of wines.
Different types of glue are at the disposal of the cellar master who chooses according to the need, after carrying out tests.
Examples: egg whites, gelatine, fish glue, bentonite….

These lees are eliminated by racking after a settling time of a few days to a few weeks depending on the glue.
