Product Details

An anti-foam agent that can be used during fermentation to eliminate messy blowoff. As soon as fermentation is over, this insoluble compound settles out and remains behind when the beer is racked. It will not affect the finished beers flavor, appearance or head retention. Can also be added during the boil to reduce the risk of boilovers. Use a few drops per gallon for boil, or two drops per gallon for fermentation. Comes in a one ounce eyedropper bottle. Keep refrigerated until use.

Great in starters
Billions of lives have been saved by using this product. Vigorous starters would push out the foam stopper and spill healthy yeast all over my stir plate. One drop and the problem is gone.

Awesome
1st time user, it prevent boil over at hot break, and saved me a lot of clean up time. Well worth the price and effort.

great for lessening blowoff in fermentation
Added a few drops to fermenter post-chill. This was the first time I was able to run the aeration pump and stone for 30 minutes without stopping to let the fom subside, so this was a great result.After, I had a really active fermentation, but I believe the Fermcap kept the krausen from going too crazy and travelling up the blowoff tube, as has happened to me the last few brews.Checked my SG after 2 weeks of fermentation and we're down to 1.002 (not a typo!). So, I'd say the Wyeast Saison Yeast 3711 was unaffected by the Fermcap, which had been my only concern.

No more boil overs
I've brewed over 300 batches & will never brew a batch without fermcap. You can turn your back & not worry about boil overs. it works like magic.

no foam!
Does what it says. no foam...NONE! My most recent brew was an extract boil for 60 mins. Never came close to boil over. In fact i only say about 6 bubbles total. This stuff is cheap and will last for many, many brews.

I agree with Lonnie Mac
Boil starters on your stove or ever plan on it? Ferment 5.5g in a 6g Better Bottle? Volume in your kettle on the high side and/or do you wish the hot-break would hurry up and get out of the way so you can get on with your boil and start adding hops?If you answered yes to any of these then you definitely need foam stabilizer. Word to the wise, even though you don't use much of it, don't run yourself out of this stuff. I did and now I'm paying. None of the LBHS around here carry it and NB is out of stock. Things will certainly get messy.

Works as advertised
Fantastic product. I use 1 drop per gallon during the hot break and an additional drop per gallon just after pitching the yeast. Even on monster high gravity beers with aggressive yeast strains, it's kept the krausen of my beers at or below 1" in my primary fermenters. Kiss your blow off tubes goodbye.

It works.
Fermcap-s works. It allows me to trade a little head space for a little more wort in my primaries. When I brew something big, the good stuff stays in my primary instead of filling the blow off vessel.

If you wanted to use this to prevent boil over for extract, when would you add it to the kettle? Right away before steeping grains, before the malt, or before the hops? Not sure how long it may take to integrate into water/mash.
James J on Jan 30, 2017
BEST ANSWER: Either extract or all grain add it to the boil kettle as the kettle is heating up but before it reaches a boil. I always add mine around 190 degrees or so, or when I start to see a little white haze starting to form on top of the wort in the kettle. Works great and no boil overs.
It's says keep refrigerated. Should this item be shipped with ice packs?
A shopper on Feb 1, 2017
BEST ANSWER: It worked fine for me, i had it sent to me using standard shipping to Georgia and it is usually pretty warm here by the end of May when i received it. I did refrigerate it when it arrived.
Is it possible to add too much? if so, what would the result be if too many drops were added?
J O on Feb 6, 2016
BEST ANSWER: It shouldn't have an effect on the finished beer since it just settles out with the trub. There wouldn't be any advantages to adding more than the recommended amount though.
