Works perfectly to reduce the chance of boil overs in smaller kettles

This actually works. Add some to your wort before the boil and it will break the surface tension and prevent boil overs when adding hops.

I use a sintered stone and aquarium pump to aerate my wort and it sure stopped the foaming. I haven't tried the beer yet though.

Prevents boil-over like a champ. Less effective during fermentation.

I put two drops into a 5 gallon ferment that was looking like it would foam over. About 15 minutes later the foam had reduced and no foam over.

Boiled 18 gallons in a 20 gallon kettle and had literally no foam! Will be using on big batches from here on!

Prevents excessive foam when boiling and to a lesser extent during fermentation

Would not brew without it. Works great in the boil pot. Still get some foaming during fermentation.

I boiled 8 gallons of wort in a 15 gallon kettle and this stuff works like magic. Barely any surface foam. Planning on doing a 10 gallon BIAB batch in the same 15 gallon kettle starting with 13.5 gallons of water and I would be highly confident of no boil over. Can't wait to use it for yeast starters!

Use a few drops in my flask when making yeast starters. Keeps everything in the flask.

What a cure for the bubbler...

I use this when I make yeast starters so I do not get a boil over on the stove. I also use it in my 15 gallon keggle so I can boil 14 gallons of wort without a boil over in that vessel as well!

A few drops of this at the start of the boil and I never have to worry about the foam boiling over the edge of the kettle. This stuff pretty much eliminates it. I've never had a boil-over using this in the kettle. I've made several batches since buying the bottle and it's hard to tell I've even used it yet. You'll get quite a few batches out of it depending on the size of the batch and the number of drops you need in each. Good stuff. Allows me to stick around for the first couple of minutes of the boil and then walk away (or at least turn my head as needed) knowing the foam is under control. My only real complaint is that it's very thick and can be a little hard to dispense in actual "drops"... so I usually just estimate.

works perfectly for starters in a flask for preventing boilovers and for minimizing loss from blowoff. can't recommend it enough if you're a serious brewer.

Just a few drops in the kettle and the foam settles right down. It doesn't eliminate boil-overs (human error) but it sure helps. Has no effect on the foam in the final product. Worth the $$.

Love love love his stuff! Makes brewing in the kitchen a much less hazardous proposition. No boil overs no fuss no muss.

I brew 10 gallon batches in a 15 gallon kettle. Without this I would boil over every batch. But with it I barely just need to keep an eye on it as it comes to a boil.

I use this with every brew and it works like a charm. It's especially handy with I'm pushing the volume limits of my kettle during the boil. However I still have to use a blow off tube during fermentation.

Have not had to use this for boil over with my 20-gallon kettle but for mixing up a starter mix it has worked great. Also a must have for anyone using the PicoBrew the end of the chill cycle can cause a lot of foaming.

A drop or two prevents the frequent boilovers I would get when boiling my starter wort directly in a flask.

Since I've used this product my anxiety regarding boil overs have gone down. I have not noticed any off flavors or taste issues with my beers.

I originally purchased Foam Control to deal with a boilover issue I was experiencing when making yeast starters. One drop does the trick. I love having it around to tame the occasional out-of-control fermentation head too. The little bottle lasts a long time and is worth its weight in gold.

This stuff is great for killing boil-overs. I use it to get a really vigorous boil going. Great for high gravity and big hopped beers as adding sugar or a fist full of hops does not require a team of spray bottles to battle the boil-over. I tried it when I filled a fermenter too high hoping to minimize blow-off but I did not notice much improvement. I also use it for starters. Those Erlenmeyer flasks love to boil-over.

No more boil overs. Especially useful for making yeast starters.

I love this stuff because not only does it help with boil overs it also helps with limiting the kraeusen during fermentation.

This stuff is fantastic. It prevents boil overs and reduces foam in the fermenter so you won't need a blow off tube. I can't recommend this product enough.

I do a starter on the electric stove with a flask. no boil over at all

I have saved allot of boil overs with this product.

A few drops in each starter and I never have a boil over mess in my kitchen

This stuff really works. Just a couple of drops helps keep the foam from starter cultures in check so the culture doesn't wind up all over your counter/stir plate.

An absolute must on brew day! No more boil over worries.

I use this in every batch never have to worry about foam over with this product

I have converted kegs which I use to brew 20l with however when I'm trying to get a double batch in its a REALY TIGHT FIT TO THE TOP. I have to go super gentle boil for a longer time and I can't afford a boil over. This product helps with that!!!! I don't use it in the fermenters ...so I can't say.
