I brewed an American Amber Ale. Within hours bubbles were coming out of the blowoff tube. The next morning the top of the wort had about 3" of fine brown foam. The bubbles coming out of the blowoff tube were coming out 2 or 3 per second. Then within 48 hours I see about 1 bubble every 14 seconds. And barley any foaming on top of the wort. Is this not good. Or a good thing. Every batch I've ever made always started slow and had a 2" layer of krausen until two or three weeks. I'm just concerned it could be ruined I'm just not sure.
