Shake vigorously before use. Mix 2-3 drops per gallon into wort when it is transferred into the fermentation vessel. If not added before pitching yeast, FermCap® should be applied carefully to avoid mixing with the yeast.
Higher rates of use or additional doses may be called for if the wort contains large amounts of trub (solids), if the wort is highly viscous, if the fermenting vessel is tall and narrow, if the fermentation temperature is high, or if foam is plentiful or robust for any other reason.
