I got a surprise a few months ago. I started to rack to the bottling bucket, but the auto siphon wouldn't work. Tried everything. Finally I got a 2 cup measuring cup and dipped from the fermenter and gently poured into the bottling bucket. I felt pretty sure it would be ruined from oxidation. But the resulting beer didn't have any signs of being oxidized. It didn't stay around long - finished it about 8 weeks after bottling. But I think the active yeast, eating the priming sugar, did a good job of scavenging the oxygen that I put into it by dipping and pouring. I still take care, but I feel much better about the whole oxidation while bottling issue.
