Fermcap S Foam Control - 1/2 oz - 15 grams
Fermcap S Foam Control saves the mess and punishment caused by boil overs and overflowing krausen. Fermcap S is made of pimethylpolysiloxane - PDMS, a non-soluble and non-toxic silica polymer that acts to prevent foaming in boiling and fermenting liquids. After boiling or fermentation ends, Fermcap S settles out with trub and yeast to be left behind after racking. Fermcap S is particularly useful when boiling starter wort in erlenmeyer flasks on a stove. Use at a rate up to 2 drops per gallon at the start of boiling or fermentation.
SpecificationsPDMS is a non-toxic silicon polymer with an FDA limit of 10ppm in a finished product. As PDMS can stick to yeast, brewers may want to avoid using Fermcap S with non-flocculating yeast strain.
