I recently used Foam Axe in both the boil and fermenter. It really worked as described. During boiling I didn't experience the "hot break" moment that I typically did, where the wort is apt to boil over quickly if your not careful. I then used it during fermentation. It completely eliminated the typical "blow-off" I almost always experience high volumes of foam generated from very vigorous fermentation. I am extremely pleased with the results and would highly recommend this product.

I like this product because it doesn't require refrigeration and it works as expected.

I like this product as a defoamer, the dropper seems hard to unscrew, though, so i gave it a 4

I use this when making 2-liter yeast starters. Stove top boil overs are messy and annoying. With this, no more boil overs.

Even though I have a 22 gallon kettle, my big beers for even 10 gallon batches would want to go right over without intermittent flame and spray down intervention throughout the whole boil. This stuff makes my brew day less stressful.

Stop fighting the foam and get this already. A few drops and the angry boil over gods are at bay. I finally got a hold of some of this and my last brew day was such a pleasure when it came to the boil stage. At the first sign of the brew gods demanding to give me more clean up work I plopped in a few drops and the eruption subsided with the quickness, I was in awe at how fast it knocked it down. I will make sure to always have this in my arsenal from now on for not only the piece of mind but the safety of my floor and time from the clean up it prevents.

Excellent boil over control in my Anvil Foundry which with a heavy grain bill often threatens boil over without constant stirring. A few drops of this and the entire boil was set it and forget it.
