I brewed a stout on Saturday with Safbrew S-33 yeast. Everything went pretty well, but I ended up with about half a gallon of extra wort so I headed off to Lowe's to get some tubing for a blow off, just to be safe. (Can you believe that stuff is about 4 dollars a foot? Sheesh.) The tubing ended up being too narrow (they didn't have a great selection) so I wrapped a bunch of (sanitized) tape around the bottom of the hose so that it would have a better seal, then I wrapped some sanitized aluminum foil around the blow off and the neck of the carboy to allow it as little contact with the outside air (and all of the cat hair floating in it) as possible.
By the next morning I had a huge krausen and a bucket of very brown star-san solution. It was also leaking around the foil, so I didn't create as good of a seal as I had hoped. While I was at Lowe's I had also picked up some 5/16" hose just in case I ever needed it (at 27 cents a foot, I figured it was worth it). I sanitized that and a rubber carboy bung and shoved the hose in to create a more narrow blow off with a better seal. I took the big blow off out and put in the smaller one. I noticed when I removed the big blow off that the krausen fell but, after about 15 minutes, it was back with a vengeance. Then, by the time I went to bed on Sunday (~12 hours later), there was no krausen to be seen, but a very happy fermentation going on.
Everything I have found in researching this has been people asking about a krausen that lasts a very long time, so that's little help to me. Is there any reason to think that something may be wrong when the krausen only lasts one day?
