When transferring from primary to secondary, assuming primary is a plastic fermenter, do most people use the spout at the bottom with a tube attached or do you use a racking cane (auto siphon) to transfer to a secondary fermenter? I've been using the spout and most of the trub rests on the bottom of the primary...but I'm wondering if it's better to siphon to avoid trub from entering the secondary. What does everyone here do?
