But thats not bottle conditioning. I had one batch, gel fined in primary, accidentally disturbed primary while racking and sucked up just a little gelled sediment to bottling bucket. Every bottle had a tiny amount of tiny floating bits that would stay in suspension a long time. I cant say that is evidence enough to prove anything, but its what I attributed it to. I suspect that if there is spent gel present when you add sugar and referment, that the little gelatin globules aren't as willing to sink as easy. No idea why.
