Prevent boil overs on the hot side, add 2 drops per gallon for a nice rolling boil. On the cold side, Fermcap keeps the krausen in your fermenter to 1/2 an inch. Fermcap works very well for brewers who use a carboy for primary fermentation. In a 6 gallon carboy there is no need for blow off tubing when you use this product. Use only two drops per gallon at the start of fermentation. If you add Fermcap during the boil you do not need to add it again in your fermenter. Used in the fermenter, it increases the bitterness of your beer (retained IBUs) by about 10%! Enough for about 20 batches. Keep refrigerated. Size: 1 Oz.
