FermCap S is a unique emulsion of an extremely effective surface active agent, Dimethylpolysiloxane, which prevents foam formation by reducing surface tension. FermCap S is classified as a "Process Aid" because of its novel feature of being completely removed from the beer under normal processing conditions. It is adsorbed onto the surface of the yeast, vessel walls and filter media. Analytical techniques accurate to 0.005 ppm cannot detect FermCap S in finished beer.

Suggested Usage: Three drops per gallon to prevent boil overs on brew day. and two drops per gallon for foam prevention during fermentation.
