Hi Matt,
Good stuff. It's probably not far from being a winner...
1) I'd add a privacy notice to the ecourse sign up. How are your opt-ins converting?
2) The header should probably be scratched and redone completely. I'd include a picture of you. Make them see it's coming from a real person. Maybe put the picture of you in action right below the salutation, to get them reading.
3) I'd more specific than "great tasting" -- that just too vague.
4) "Dear Fellow?" -- maybe just one or the other.
5) I'd lose the "since you've gotten this far" -- it's too early for that type of line.
6) Need more subheads.
7) Include some shots of you doing this stuff. Position the picture strategically to get them reading the text again.

Lines like this would make GREAT subheads:
"Think about this...Modern factory produced beer is loaded with inferior ingredients, chemicals, and low-cost 'adjuncts' ."
Center, bold, 16 pt font. Let your sub-heads convert the skimmers.
9) Your testimonials ned to be more promiment, plus have their only headlines. Include pictures. They are hard to read right now on the colour with no margins.
10) Your chart needs a headline summing it up. Or and arrow coming in fron the side.
I wouldn't be surprised if you could raise the conversion rate dramatically on this by just doing the above and make the design much more readable and professional looking.
If you threw in a few bonuses... Made a DVD version, possibly, you could raise the price to $97 and get MORE orders.
Let me know if you'd like some help with the copy and the design -- if you'd be willing to give me a percentage, I might be interested. It looks like a fun project.
