ive used hulled millet in a few beers. i have not home malted it yet though, just roast waft crack and 1 hour steep. generally i use it in conjunction with tapioca extract. it has a really nice flavor, ends more on the sweeter side, and has a nice heffe aspect to it. i sent a tapioca millet strawberry blonde to lcasanova a few weeks back too.
i just finished a keg of tapioca millet with hazel nut extract using a home isolated heffe yeast, it finished sweet. like candy sweet and about 7 %alc, i called it hummingbirds heffless
