Kerry Fermcap S boil over and blow off control -
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.
