Couldn't find much in a search about this. It sounds really simple and I feel slightly retarded about asking this, but does anyone have a technique for making sure that when I drain beer from my carboy into my keg via a spigot and gravity, that the beer completely fills the tubing and flows quietly into the keg? Last night I was kegging a batch, and the beer just kind of ran down the walls of the tubing, causing a lot of oxygenation. I couldn't get it to completely fill the diameter of the tube. I'm sure it's something really simple, but I couldn't figure it out.
