I didn't read through the whole thread and I know this is an old one, but I just started brewing a few months ago and after brewing several extracts batches, I went AG. I just finished a 60 min boil starting with 7.25 gallons in an 8 gallon kettle. I used Brew Haus anti-foam agent and never even came close to a boil over and I had it going pretty vigorously using a bayou Kab4 burner on full blast. Love this stuff and will use it on every batch from now on.

Started using Fermcap with this latest batch. Did 4 1600 ml starters, 2 each of Wyeast 1388 and White Cry Havoc. One drop in each and foam stay at less than 2". Did 10 gallons of Kolsh and 10 gallons of Blond Belgian yesterday, pitched about 6 PM - added 10 drops (2 drops/gal) of Fermcap to each fermentor and they are bubbling like crazy this morning with about 1 to 2" of foam.

This will be a staple in my brewdays from now on.

Been using it in all my batches in the fermenter for about a year. Seems to work great! When I have forgotten, I have blowoffs (13 gallons in a 15.5 sanke keg) and when I remember, they slumber quietly in the fermentation chamber Never tried it in the boil, but will from now on!

This is included in the midwestsupplies product description.... I was unaware of the change in bitterness!

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.

The bitterness is increased due to the lack of blowoff which carries some of the hops oils away, in German brewing texsts this sort of blowoff supposedly smooths out the bitterness.

Is this a true statement? I thought I read here that this was not the case, That you have to re-add at the beginning of fermentation?

Anyone have experience with this?

No, it's not necessarily always true. There have been many times I've added it to the kettle and still needed to add it to the fermenter.

My experience would agree with you, folks. I definitely don't get the fermcap effect in both the boil and the fermenter. I think the products naturally sinks to the bottom. So, if you let your trub settle out and rack off the trub into the fermenter then it gets left behind.

Anyway this stuff is great. I haven't really been using in my buckets because it doesn't matter, but I recently got a BB and cleaning all that yeast and krausen off the inside top of the BB is quite a pain. I did buy one of those carboy cleaners you hook up to a drill. I don't know why I waited so long. It pays for it self when comparing to the cost of constantly soaking in PBW.

It's actually the opposite. It forms a thin skin on the surface, and clings to the kettle/fermentor wall as you drain them.
