There are a lot of resources about beer brewing on the Internet. A recent trend is that people make podcast which are audio and video streams that you can download and listen to whenever you feel like. I listen to a few of these regularly, and I'll present each of them here.
The first one out is Basic Brewing Radio and its sibling Basic Brewing Video. This podcast is lead by James Spencer and his co-host Steve Wilkes. Once a week they post a new audio programme between 30 to 70 minutes long. They talk about all aspects of brewing and do interviews with other homebrewers and professionals. What I like about it is that it is posted regularly and that it is not too long and that it is very much to the point. The video programme is more sporadic, and shorter, and typically helps fill in the gaps of the audio podcast. It is a great resource for home brewers. Check them out, I very much recommend listening to their podcasts.
They have also produced two DVDs, Basic Brewing: Introduction to Extract Home Brewing and Basic Brewing: Stepping into All Grain, which I'm sure is a great way to get introduced to extract and all-grain brewing.
Interestingly their latest video podcast is about brewing a harvest ale with homegrown fresh hops.
