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.

Maybe I shouldn't use it as much as I do -
- but I love this stuff. Controls boil-over in the kettle and keeps the foam down in my yeast starters.

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.

Awesome for reading hygrometer
A couple of drops in your gravity tube and the foam is gone. Now I can read my hygrometer and get accurate gravity readings...awesome

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.

Great product.
I've used this in all 4 batches that I've made. So far it has worked out great. I've hadn't had to use the blow off hose that came with my go pro one gallon kit once. I will continue to use this product.

Works for everything but fermentation blowoff
It works as advertised as a preventative against boilover - since I use extracts in my brews, this is essential brewing equipment for me. However I have used it several times in my fermentation vessels to prevent blowoff, but it doesn't really work for that (maybe my beers and starters are too big!?) However a blowoff tube isn't such a hassle, so that isn't a huge deal. I have also used this stuff successfully when making mashed potatoes - no more boilover there either. Highly recommended if you use malt extracts!

Love this stuff!
I use this in the boil as well as in the fermenter. It prevents boilovers in the kettle and then also usually prevents the krausen from blowing out of the fermenter. Highly recommended. Does not negatively affect head retention.

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.
What is it???
jesse k on Feb 4, 2018
BEST ANSWER: It's a Foam inhibitor. I use it at the start of the boil and it completely prevents boil overs. Pretty cool stuff. I've also read that others use it in the fermentor to prevent blow offs. I haven't used it for that but maybe putting it in the boil does double duty. It drops out after fermentation so no worries there.
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.
Is it recommended to filter your beer when using fermcap-s?
A shopper on Apr 22, 2018
BEST ANSWER: I do not filter my beer fermcap drops out into the trub I use it in every brew helps with boil overs you still need to watch for it it just makes them less violent
What is the shelf life after opening? Its been refrigerated since received.
A shopper on Dec 1, 2017
BEST ANSWER: Northern Brewer was purchased by the “Disruptive Marketing” arm of AB InBev. I would recommend purchasing this item from another vendor.
