[quote=“mattnaik”][quote=“Hades”][quote=“mattnaik”]I’m a big advocate of this stuff
Ever since I’ve been using this, I haven’t got any krausen higher than an inch thick even during the most vigorous fermentations. One bottle will last you half a lifetime.[/quote]
Perhaps this is what I need to be adding to a starter to prevent the nasty boil over on my wife’s stove that happens every time. Can you vouch for its claim not to kill head retention?[/quote]
I haven’t had much of an issue with head retention since I started using it but it’s not really a quality I consider important to me in a beer so my standards for this might not be what you’re looking for.
I will attest to the ability to prevent boilovers for starters. I have a quarter inch of space at the top of the pot I use to boil my starters in and I have never had a boil over. Just put 3-4 drops in there before you start your boil and you’re good to go.[/quote]
I edited my last post after Google searching the product. Hopefully others can weigh in on it and provide some links to current info. If it was unsafe I am surprised it would be marketed without some type of warning… also I have been making starters in a Pyrex Erlenmeyer flask, those suckers just WANT to boil over!
