To me the best thing about brewing TV was the Dawson grain to glass episodes. It's fun to see the whole process, from recipe to design to tasting, and it really helped me learn more about how ingredients and the process can really change a beer.
I'd love to see Dawson, or another really knowledgeable brewer do something like that regularly. That's basically the format Don O uses, and he proves just how simple the process can be.
I'd love to see the AHA try something similar. Maybe even reach out to specific clubs/brewers and have them help to provide content.
