All seminars from the 2013 National Homebrewers Conference are now available exclusively to AHA members for download! Presentations include audio recording of the seminar as well as any visual aids the speakers used. More info here: http://bit.ly/HBC13sem
If you haven't already, check out the 2012 seminars as well. Between this year and last, there is a lot of great information for brewers of all kinds (cider and mead makers, too!).
Non-members--you can check out a free preview of Mitch Steele's talk from 2012. The link above will point you there!
