Yup unmalted... I have access to commercial grade zymes. I cereal mash, add enzymes, hit my temps depending on style then sparge... so the only difference between my set up and a regular AG set up is that I use a burner under my tun. I use the grant from my nano as a homebrew tun. My grant is just a stainless steel 15 gal kettle from amazon it was dirt cheap.
