Protosol is a processing aid so is not required to be listed on labels. Protosol does not contain animal derivatives. Beer filterability is enhanced due to removal of solids.
Protosol is typically added to beer at rates in the range 20–200ml/hl. The level of solids in the beer will determine the required addition rate. The correct addition rate is best identified by performing a lab-scale optimisation test and assessing for clarity and sediment compaction.
