I'm the same kinda noob Torilen is, so I'm just piping up to say I'm glad he's doing what he's doing, and it's a lot like what I like to do. Hey, experimenting is fun!! Even if you botch a batch, the quest and process are intrinsically enjoyable, and I like to read along.
That said, dude, I totally would have caught that your oatmeal can't be fermented unless it's malted or somehow converted from starches to sugars. I think you could even chew your oatmeal and spit into your carboy and at least your saliva's amylase enzymes could start the process - isn't that chicha? I dunno, it's something.
Anyway, I'm still eager to hear how this turns out one way or the other, I've not yet been brave enough to attempt anything like a "beer", though I'm considering it. Let's see what you get!
