Hey, I´ve brewed 6 gals of Pliny the Elder clone last saturday, everything went normal in fermentation until yesterday. After 4 days of normal fermentation at steady room temp another high krausen has appeared to reach the top of carboy and even inside the airlock (i had to replace it with a clean one).Foam is weird, I don´t know ,is the first time I see something like that, it is a large bubbles foam ,looks very weak but has completed the whole dead space of fermenter. I opened fermenter and sprayed alcohol 70 % to get foam down. There is no bad odor, in fact it smells fantastic but I didn´t want to take a sample to do not add more risks of an infection. It is a OG 1080 beer , I used 2 packs of S-05 reydrated.I have a pic where I drawn an arrow to mark the first compact krausen level.Has anyone any idea or experienced the same thing? https://www.flickr.com/photos/tebuken/
Interesting, I've never seen that. Maybe there was a second strain of yeast in there somehow. (even though that's probably unlikely)
Most likely, this is nothing but a normal fermentation that took a couple extra days to reach its peak. Don't worry about the "foam" (which is of course krausen) looking different from other beers you've done: the appearance will change from batch to batch depending upon a variety of factors. Don't spray anything else in there! Just put a blow off tube on, RDWHAHB.
