I recently adjusted the gap on my grain mill to give the smallest gap. I was playing around with going as small as possible until I start to cause problems, i.e. stuck mash.
I've brewed very similar recipes only, changing one ingredient, about 5-6 times before. The only thing I can thing to blame the haze on is the smaller crush.
Will a smaller crush cause a haze?
