Then the week happened. I didn't think much about my beer at all. Until last night, when I opened up the closet and found this:
|Krausen in the Airlock. If this clogs up, the whole stopper flies out on a wave of yeasty foam, painting the ceiling.|
I went and got one of my older "you can push it all the way into the bottle by mistake" stoppers and a length of blowoff hose and a growler of sanitizer, and set this up:
|Yeast Fountain Avoided.|
It started bubbling away within minutes. I should have know better. I have been starting all of my beers with blowoff hoses until this last batch. I've never had such a big weird krausen come up before, but this just goes to show that it can happen, even on a lower-gravity beer, and that it might happen a few days into fermentation. In these colder months, when my clothing closet doubles as my fermentation chamber, it pays to pay attention.
