Let's talk about Foam Control drops (aka Fermcap)

[johngaltsmotor]

should be able to, I recently did a 14gal boil in a 15.5 gallon keggle (never would have considered it without fermcap)

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.

 

[rockfish42]

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.

Me to.seems like I usually need to add it to the boil and 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.

Anybody ever use Fermcap-AT. It's supposed to be a silicone free product that uses canola oil instead. It meets the FDA guidelines for not needing filtration (unlike Fermcap-s).

 

[Toy4Rick]

This is something I am going to try. Since I don't rack from kettle to fermenter but instead use a paint strainer filter, it seems to me that it should carry over and I won't need to add more to the fermenter.

I'll let you know once I try it out

Yep, that's what I use now if I use it.

Do you know a good place to order it. No one around here caries it and the only place I found it online wanted $21 for 2 ounces shipped.

Does it work as well as the "regular" Fermcap?

 

[Denny]

Nope, sorry. I got it from a wholesaler as part of a group grain order. We got a gal. and split it up.

 

[Denny]

Identical as far as I can see.

 

[smccarter]

After having read this thread, I bought some fermcap. I've used it in the brew kettle for my last 3 batches and can say without any hesitation that I just can't stand the fact that I had never heard of this stuff before this thread.

I brew on the stove top in 8 gallon brew kettles, so for 10 years I've been dealing with the threat of boil-over. With fermcap I don't have to worry about boil over any longer.

Long live fermcap... I'll never brew without it again.

 

[Zippox]

I don't have the time at the moment to read all 6 pages. I made a yeast starter last night that krausened over and hit the aluminum foil off. I am making a new yeast starter in a couple hours... So... do I add this during the boil or after I have cooled and transferred it to the flask?

I want to be certain I don't get another foam-over.

 

[Nightstrife]

I just used it on my last brew... I dropped about 8 or so drops in about 10m before it boiled and I didn't have any worries about boil over. I was still ready to shut off the heat but it went well

I add after the boil. Pretty sure that stuff is sanitary.

 

[JBushnell]

I use for stir plate starters. I add it before the boil and it allows me to boil in the Erlenmyer flask and prevents blow off on the stir plate.

 

[Tbattisti]

I've been using Fermcap-S for a while, and actually HAD my first boil over with it on Friday. 10 gallon pot, 7.25 gallons of wort. When I added my bittering hops, it actually boiled over. I had 10 drops of it added too! WTF???

 

[Schlenkerla]

So I wanted to see how expensive this would be. For the $6.99 fermcap stuff (4 fl oz) at NB:

(1 batch/10 drops) x (1 drop/0.05 mL) x (1 mL/0.03381 fl oz) x (4 fl oz/1 bottle) =

236.6 batches per bottle. Sounds good to me.

I just used up my first bottle of this last night. Looking at the date on this thread, I wonder if my next bottle will last that long?

 

[kh54s10]

I posted that I used it sparingly. Since then I had boil overs even with it and have had blow off with it so I just stopped using it. I know it is minimal and supposedly the same as Simethicone anti gas medicine, but I decided I didn't want that in my beers.

 

[Phildo253]

I have been using fermcap for every boil for about 2 years. It has saved my bacon quite a few times. I never have to worry about boil-overs. I tend to use a little more than recommended. I find, for my setup about 24 drops for 7.5 gallons at the start of the boil works very well for me.

 

[kh54s10]

If you just turn down the heat at the start of the boil you don't need anything artificial....

I do about the same thing. I like not having to worry about it.

Most of the time the risk seemed to be right after the first hop addition.

Prior to using it I stirred, blew on it hard and dialed down the temp to 8/10ths on my electric stove. In keggle I never used it since it so oversized.

I'd stand by and watch with beer in hand. [emoji481]

Holy moly. I use 5 drops for the same amount, and it works like a charm. Takes a few minutes for the foam to dissipate from the start of the boil, but then, wah lah. Magic.

1 drop for my 1.5L starters does the trick too.

i will have to try that on my next boil. i started with what the directions called for, which was 3 drops per gallon and then adjusted from there.
