Colle Perle is a hydrolyzed gelatin solution. Primary uses are clarification and the removal of bitter tannins and phenolics. Colle Perle flocculates and settles well. Desir­able aromas and flavors are retained while harsh char­acters are removed. It is particularly useful to optimize potential of hard pressed product. In white wines it can be used in conjunction with bentonite to compact lees.
