I discovered these videos on youtube a while ago. This four part set is a great introduction to kegging. I thought they were very helpful and very well done. They were created by Chris Knight. I’m very impressed by the production quality of these videos.

He also has a series on all grain brewing. I haven’t watched them, but if the production quality matches the kegging videos, I’m sure they’re great.
