Fermcap-S Foam Inhibitor- 1 oz.

$3.49

Product Number: 6957

Availability: In stock

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.

No more boil overs! Review by danr

This stuff works like magic. I now use it every time I brew. I can now safely leave the room during the boil without worrying about coming back to a mess to clean up.

Works as advertised. It prevents boil overs and saves me some clean up work.
IF you do stove top brewing, it can really make a difference.

I can do a full boil and have the wort an inch below the top and not have a boil over. Fermcap saved me from having to buy a bigger and much more expensive pot.

Love this stuff--makes boil overs a thing of the past Review by MarkR

Boiling the yeast starter flask was always a chore due to the small neck and boil over potential. And, even with a 10-gallon pot, I managed to boil over a few times, creating the mess of all messes. This simple, cheap and easy solution fixed those for good--don't know why I did not try this sooner! Highly recommended.

It saves me mess and clean up and has no effect on the beer. I can fill my kettle to within a couple of inches of the top and not worry.

Little bit goes a long way Review by Brandon

I was surprised at home much of an impact this had on the level of foaming. I read the reviews, but even still, I was a little skeptical. Worked great!

A CLOSE CALL Review by Larry AP

The first brew I did was a narrow escape from an all out BOIL OVER. From that event forward had to change. After reading all of the reviews on MIDWEST website I decided I would give it a try. Fermcap-S works great, wouldn't brew with out it now.

lets you brew larger batches Review by Sample

Fremcap is da bomb. It flat out prevents boil over. The more I can fit in my pot, the more beer i can brew. And now that I can fill my 10 gallon put up to the 9 gallon level means i can brew 7.5 gallon batches instead of 5 gallons.

Lets you use smaller brew pots Review by Sean

I am now able to use a 7.5 gallon pot without fear of a boil over. Just 5 drops and my problems are over. When its done it settles into the trub in the fermentor leaving nothing behind.

This stuff blew my mind, not my air lock Review by Scott

Product Rating:

I had been having trouble since upgrading from my old bucket to a better bottle for primary of too much foam causing a big mess that I had to switch to a blow off tube. I tried this on my last batch a RyePA and not only did I have no foam during the boil, even at addition times, but it kept the foam to less than 2" in the fermentor which means I can go back to my air lock which I find simpler and cleaner of a setup. I love this stuff, I will use this for every brew from here on out.
