Finding malt anything ,or finding barley/wheat is tough in my corner of the world -- tropical developing and Islamic nation. Corn and rice are plentiful and cheap, as are various byproducts of their refinement. I have made many wines before and consider myself pretty good at the process. Now that I've made a connection who can hook me up with affordable hops, I'm wanting to explore beer making with alternate grains.
I'm seeing general wisdom that 2 pounds per gallon is a good grain recipe. or roughly 250 grams per liter. Could a decent beer be made from corn and rice? Flaked rice that quickly and easily becomes a porridge is easy to come by here, as is cornmeal. I was thinking of making a mix of cornmeal and instant rice, boiling for ~20 minutes until the grains begin melting, then otherwise following recipe for adding hops to a wort, adding enzymes once things cool down, and adding enzymes again with yeast once it's about room temp. I'd consider adding oatmeal as an adjunct if initial results are promising.
Balls of koji / "Aspergillus oryzae" mixed with yeast are also pretty cheap and easy to come by here. From experience I know it can produce a pretty good "sake" and suspect it should work on corn, I'll test with that before buying "proper" expensive enzymes.
If people have any useful advice or tips for making beer with limited resources, it would be very much appreciated. Tried googling for answers here but a lot of the discussions were long ago or depend on resources I don't have easy access to. Once I begin experimenting in this area I'll try to bring updates to this thread.
