A fellow brewer has just pointed me at these homebrew podcasts, haven't had a chance to check them out yet but there's a lot of content there and some of it looks interesting

An excerpt from the site:
"At Basic Brewing Radio, we're all about home brewing. Each week, we hope to bring to you interesting interviews with people who can shed light on the hobby, share an interesting story, or give expert advice to help us all become better home brewers."
