Vermont Smooth Posted January 28, 2011 Share Posted January 28, 2011 I am just learning to work with grains and am currently frustrated by an illusive negative starch test. I am cooking corn meal and treating it with alpha amylase. The textbook says not to go on until I have a negative starch test. I can see the gelatinization and liquefaction effects, and the mash gets sweeter, but the iodine test still shows purple. Can Anyone advise me here. Even to say, yo bro, you just got to do it over til you get it... Link to comment Share on other sites More sharing options...
