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.
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!
Anti Foamer.... GREAT
Works Great when making yeast starters
Great for yeast starters and boiling wort
I put it in yeast starters, also put 6-8 drops in the boiling wort.
For emergencies
Handy to have it around when you suddenly need a couple of drops...or a blow off tube.
