Hello home brewers! I have a question for you more experienced brewers out there. I have brewed my fourth batch ever and the last beer I brewed was a partial mash clone of Dogfish Head 60 Minute IPA. My OG and FG were right on after 1 week in the primary fermenter (fermented in a food grade plastic bucket with airlock). I racked into the carboy as shown in the pictures. You will notice I am dry hopping with hops in the secondary. About 1 week after racking, I noticed what is shown in the picture on top of the beer and I'm not sure what it is. My first three brews never had this Krausen/mold like substance on the top so I am wondering if this is normal (I wouldn't think it would be Krausen since active fermentation has been complete for about 2 weeks)? I am going to bottle it in three days (will be 2 weeks in the secondary) so at that time I can take a sample taste but just wondering if any of you have seen this before? I'm concerned that my beer may be infected; I was really careful when I brewed and racked making sure everything was sanitized. I guess the final conclusion will rest with how the beer tastes but just wondered if this looks normal to any of you out there. I should add that this was the first time I ever added Irish Moss while brewing and wondered if this is the result of using Irish Moss?
Thanks in advance and cheers!
