    Anyone use this to cut back on the foam?

    Just brewed a NEIPA using imperial juice yeast and it was a super aggressive fermentation period. I probably lost a half gallon of beer from the foam coming out of my blowoffb tube.

    I'd like to get some if it would make a big difference and doesn't make any off flavors or anything.

    Thabks!

    Can't answer your ?, but i plan one trying that yeast and i would open ferment for a few days with cheese cloth soaked in starsan covering it to get max esters and add the airlock when the storm calms down.
    BTW what's with your name.Planning a Brewery one day.

    Used it many times with great foam control help and no apparent harm to my beer.

    I used to use it. Worked fine. But I found I was solving the problem with more headspace and opted for less chemical.

    Never used it, but when in doubt that all the beer stays in the fer mentor, I use 2 carboys and lose nothing

    Only if ever win the lottery and get the capital to open something like that.

    It would be a brewery / taproom with a large area to play the game of Kubb.

    It will never happen. But something for people who try my beer to check in on Untapped.

    I use fermcap when I remember to pick it up from the store. It’s been a few batches.

    I have used Fermcap-S many times fermenting high gravity beers. It does indeed mitigate krausen (foam) and the resulting beers turn out just great.

    Cheers!

    Baby Gas-X is the low cost alternative to Fermcap-S.
    (1 fl oz: ~$3.70 Walmart v $5 More Beer v $3 Five Star brand [1/2 oz])

    Baby Gas-X (1) the same active ingredient as as Fermcap-S (2)
    (1) simethicone: polydimethylsiloxane + hydrated silica gel
    (2) dimethicone: polydimethylsiloxane

    Are the two products of the same concentration? Fermcap-S provides directions of 2 drops per gallon. Is the Infant Gas Relief the same?

    Cheers!

    I came here to say this! Been using generic baby gas drops for years with great results. If babies can handle it I think we beer drinkers will most likely be fine. 10 drops per batch of 3 gallons.

    Baby Gas-X has 20 mg simethicone per 0.3ml drop.
    Couldn't find an ingredients label for Fermcap-S.

    I add 2 drops / G to the boil after skimming the hot break w/excellent results.

    Does it reduce the co2 produced from the fermentation process? If so does it ferment differently?

    minderbender Initiate (185) Jan 18, 2009 New York

    No it is all about reducing the surface tension (or whatever) so that foam doesn't form as readily. It has no other effect whatsoever on the fermentation.

    I use it in every batch. Keeps boil overs to a minimum and krausen stays in check.

    How much per 5 gallons?

    I’ve been pondering Fermcap since I may be able to cram more wort
    Into my fermenter. It would be nice to get 13 gallons or so in there (instead of ~11).

    Question: is there any noticeable effect on head retention?

    I wish I had remembered I had the stuff for my recent fermentation. I pitched 2 packs of Notty into an IPA. By the end of the second day I had krausen just starting to come oput of the airlock, and by the next morning a total mess. And this was with 2 gallons of headspce in the fermenter! Cheers!

    I actually don’t measure it. I would say at least 10 to 15 drops.

    Purely anecdotal, and based on experiences that are >5 years old, but when I was using Fermcap S in the boil, and bottling, I actually felt I was getting a denser looking head that lasted longer.

    Realize there is potential to misinterpret. I did not use it in the bottles. I just meant that thes observations occurred before I got a legging setup

    Anyone have experience using it in a starter? I'm thinking of making a 2L starter in a 2L flask and using fermcap to keep it from overflowing. Fool's errand?
     
  26. utahbeerdude

    utahbeerdude Disciple (366) May 2, 2006 Utah

    I always use it in my small boil for my starters. It will definitely help, but you may still get some krausen during the starter's fermentation, depending upon the level of activity. Cheers!

    Thanks.

    Have you ever added it to your starter after the yeast is pitched?

    Yep, I do that all the time--I don't add it as a matter of course, but only if it looks like it needs it once the yeast get going.

    No, I figure what I added to the boil will still be in the starter, so I don't add more. No reason you can't add it after pitching the yeast. Cheers!

    Update - I made a 2L starter in my 2L flask yesterday afternoon. I didn't add it to the boil, but added a drop to the starter before heading to bed last night. This morning there was just a slight ring of bubbles, so it appears to have controlled it completely.

    Thanks for all the starter insights.

    Fermcap is one of the more underrated tools in my brewing kit. I've made 3 gallon batches of a blonde ale in my 3.2 gallon Speidel and, using Fermcap, no issue with blowoff using WY1272.
