Kerry FermCap® S is a unique emulsion of dimethylpolysiloxane. It is
an extremely effective, surface active agent that prevents foam
formation during fermentation by reducing surface tension. Reduced
foaming increases fermentation capacity and prevents mess, improves
alpha-acid utilization and CO2 recovery, and prevents hazes
due to collapsed foam. Because of the novel behavior of FermCap®, it
completely adsorbs onto the yeast, vessel walls, and filter media. No
FermCap® remains in the finished beer.
FermCap® S should be stored below 85°F, but should not be allowed to freeze.
