While I don't have that disease, the idea of gluten free has me interested. We grow a lot of millet, milo, etc down here. I'd hate to have to malt some then try it out. I emailed a couple of ag type companies today to see if there is some malts I can buy.

This is a great idea!

I am curious about your abv% :)

At this rate we may need a gluten free recipe thread.

The ABV just happened!

I agree a Gluten-Free recipe thread would be great. I also think the AHA needs to add the category to its style list.

It sounds good except for the liquid yeast would contain gluten

sounds interesting to me. how are the starches in the corn and oats getting converted?

I imagine if you have yeast culturing equipment (petri dishes, inoculating loop) you can make an agar plate/slant with sorghum syrup instead of malt extract and inoculate it with any liquid yeast from the inoculating loop, growing this on a agar gluten free plate then making a gluten free starter should allow to use any yeast in a gluten free beer.

I am not worried at this point about the small amount of gluten in the yeast. I don't have an issue and am really only working to see what the ingredients taste like so I can try further experiments. That being said, I am planning to dump the barm off the yeast prior to pitching, I will be saving the yeast to use as a purer culture the next time.

As for the corn and oats, they are both rolled and so I will just be cooking them in a gruel like mix to get them to work their magic. The corn is gelatinized already, and the oats are being used in the same way roasted barley would be used for color and character. I am not counting on it for extract, although it will add some.

I'd be tempted to use some alpha enzyme concentrate to convert the corn & the oats.

Brewpastor can you please explain this to me. What is a "gruel like mix" ?
Cheers

If you want to carry the experiment all the way through, Wyeast does offer its American Ale II (Anchor strain) in a gluten free version. They also offer their Bavarian Lager strain in a GF version, too.

I'm intrigued with this beer. I'm eager to hear how it turns out for you, BP.
