Denny,
Great question and I'm smart enough to admit; that I'm not in a position to answer the question with any accuracy. Maybe, I'll have the opportunity to learn more if the GC opportunity works out :-)
However, if you'll allow me to reference my own personal experience, I think one of the biggest problems is poor first experiences. Newbies like me, THINK that if they can cook dinner, SURELY they can brew beer. After all, they're professionals, watched a Youtube or two, read the directions, and stayed at a Holiday Inn Express :-)
If anyone knew an easy solution to this, it would be you; but I'm confident we can do more than we're doing as an industry. COVID's forced validation of virtual education has provided AHA with a whole new way to reach homebrewers and now on a worldwide scale! I've personally experienced how online education can make a difference in my own brewing skills. I believe in virtual training and would appreciate the opportunity to help the AHA do more of it.
I know this has nearly been a life mission for you and your books are fantastic. Maybe we can adapt your books as a basis for AHA virtual training (if you would allow it)!
