Hey, thanks for the feedback! I'm glad you enjoyed it
. All the verbal feedback I've gotten was very encouraging, but the post-presentation polling data was a little critical....with no details to it, of course.
I frankly haven't heard of trying to separate out the yeast from the rice solids. There is no particular layering of the solids or the yeast, it's just one big gooky mess.
tell you from first hand experience that I did not get any yeastiness from the solids when I made a nigorisake, if that helps
I also have not heard of any attempts at polishing one's own rice, but I'd love to hear the results of anyone who did!
PS I did submit for another seminar topic, this time on electronic controls 101--basically a primer on all things electronic associated with the brew day. Hopefully I'll hear good news in a couple weeks!
