Well, I bottled it and forgot to take a picture but after looking through the infection thread I'm starting to think its brett. The bubbles are white just like the ones in most of the pictures I saw. The only thing confusing me is that in the pictures, the entire carboy is engulfed in the bubbles while I only had one or two bubbles about the size of a nickel. Also, it was on oak chips for a couple of weeks and I read that brett can come from oak. I didn't really notice any huge difference in smell or taste though.
