I have been brewing since 1997. I have always done an iodine test after the initial mash. In the past, when the iodine test doesn't pass, I let it go for another 20 minutes or so and then all is well. Today, I am mashing a Northern Brewer German Alt Beer. For the life of me, I cannot get this test to pass. Any thoughts? Btw, I currently use a Brewers Edge Mash and Boil system for the last year which has been spot on all the time. The only change is this is the second time with this system I crushed the grains myself using an really old Phil Lysterman Phil Mill. I have used it in the past but have been lazy for the last decade and bought pre milled grains. I made sure to split the grain but leave the majority of the husks intact. I did not pulverize this.
