Using a standard 2-roller homebrew mill, I crushed each malt using four different gap settings. The gap settings were 1.25 mm, 1.0 mm, 0.75 mm and 0.50 mm, and I used a feeler gauge to confirm these gap setting between each milling. After milling, I performed a grain sieve test on the different malts and crushes, and recorded all of the …
