Q: How does this product compare to Fermcap (A12)? Same active ingredient? Is Fermcap suitable for yeast starters? Thank you!
A: Same active ingredient, and both Fermcap and Antifoam are suitable for yeast starters.

For emergencies
Handy to have it around when you suddenly need a couple of drops...or a blow off tube.
Great for yeast starters and boiling wort
I put it in yeast starters, also put 6-8 drops in the boiling wort.
Anti Foamer.... GREAT
Works Great when making yeast starters
Highly recommended
I have used this a couple of times now and it works great. I used 10 drops for a 1.5 liter starter. At that ratio it still foamed up a little bit, but I just turned the heat down to a slow boil and it was perfect. I'm glad that I found this product because it makes yeast starters an easier process by boiling and chilling in the same vessel. Thanks again William's Brewing!
