I always thought my LHBS was full of it when they told me to discard the bottle after a year or so. Anyways, I hadn't brewed since last April and decided to do a quick extract batch on the stove top today. Got my boil going, put in the Fermcap-S and took the trash out. In the two minutes it took for me to run out and run back in I had a hellacious boil over.
It didn't seem too bad until I pulled out the burners and found this mess underneath. All told, I ended up losing between 1 and 2 quarts of my boil volume.
Moral of the story... never leave your boil unattended, even if you are using Fermcap-S. I'll chalk this one up as a learning experience and advise any other Fermcap users to make sure they know how old theirs is before they brew.
