Creating DRE (Dried Rice Extract) or similar results question.

Would it be possible to create DRE by making your own mash of long rice white rice (hour boil at 160-170 degrees), drying it, and milling it down to a powder?

I know from making saki the process needed to get the rice right. I'm just wondering the amount I would need for a 5 gallon batch. Would 1lb of rice be sufficient? I'm trying to make a nice light ale or lager depending on the yeast I use.

Has anyone tried using rice (rice that's been boiled/steamed) in the primary fermenter (with your wort) and then separate the chunks out to the secondary?

Thank you!

No, for the starches to be converted to sugars you need to mash the rice. In saki, the Kome-koji does the conversion. You can mash rice by itself using alpha enzyme.

Ahh, ok. So I just need to mash it first. Thanks!
