Spanish to English Other Wine / Oenology / Viticulture

Hi, I'd appreciate your help with this term.

There isn't much context, but I will explain.

It is part of the process of making wine that follows cold stabilization and is a filtering process carried out with soils. Not the one carried out before cold stabilization and after alcoholic fermentation, which in this case has been done with Bentonite in a soil filter. This one is carried out at the very end with even finer soils to give it a glossier appearance before bottling.

Thanks :)
