I've got my BPA in the secondary. I pitched it on a yeast cake from a previous IPA. It has been aging about 2 weeks and I noticed today that there were some white and yellowish moldy looking floaters about the size of a pencil eraser. One note, I did forget to put the inner piece to my airlock in and even though the top was on I guess some nasties could have had acces to my brew. The brew smells great. Any thoughts?
