Well, to be fair, this particular glass was from a swingtop that I need to replace the gasket on. It foamed pretty heavily when I opened it, but the head died down in a hurry. I'm going to try one of my regularly capped bottles as a comparison, so the story isn't over yet.
As for your other suggestion, I may very well, try Cascade hops the next time I do something like this. I just wanted to keep hip additions as simple as possible for my first time doing something like this.
