I know this is old, but I found it searching.
I just did Midwest's Bavarian Doppelbock. So far so good. I got an OG of 1.087. Spent 3 days in my beer room at a steady 70*F, then nine days in my cold room at 55*. Just pulled it out to do this diacetyl rest thing, back into the beer room. Tomorrow I intend on racking it to secondary and putting it in the fridge, where it'll remain, if I can stand it, until the beginning of March.
I followed the Midwest recipe without changes as I'm too new to start mucking about with kits. Plus, I'd like to try a kit out first, then if it makes a good beer, then I can order the same kit and start changing/adding things.
One thing to note is that Midwest's direction don't tell you what to do with the supplied champagne yeast. I wrote them and they told me to add about half the packet at bottling. Not sure I like that level of "detail". I don't want bottle bombs.
I'll let you know how it turns out.
