I found this on another site, it is called Vinoflow FCE.
See page 19 of this link.

"Vinoflow FCE is used to accelerate aging on lees, allowing
for shorter maturation periods in a tank or barrel. Add
Vinoflow FCE just after alcoholic fermentation to aid in the
degradation of yeast cell walls, resulting in the liberation of
glyco-mannoproteins and the enrichment of colloidal
substances. Vinoflow FCE produces silkier textures and fuller wines. A blend of beta glucanase and pectinase,
this enzyme also helps with the natural clarification and compaction of lees. Vinoflow FCE is purified to control
cinnamyl esterase activity, thus protecting the aroma of fine wines. Use of Vinoflow FCE requires a one-time petition
to the TTB. Contact Gusmer Enterprises for details."
