I might be coming into a 50 lb bag of crystal 40 from a friend. It's already crushes so I'd have to use it fairly quickly. I was thinking of doing a smash with the c40 and some hops (to be determined). After a bit of research it might not convert over all the way. So, with that I was thinking of adding some Amylase before fermentation to help convert the rest of the starch. Does anyone have an experience with this? I mostly want to do it for the science and learning. I'm not expecting anything amazing (though who knows!?!?).
