I currently looking to brew Deschutes Obsidian. The recipe calls for .65 kg of Black Roasted Barley (500L) and .05 kg regular Roasted Barley (300L). In my area the lighter stuff seems to be fairly tough to find (I usually go to Morebeer). Since it is such a small amount would it just be easier to just up the Black Barley a tiny bit or possibly skip it all together? Wanted to see what others thought.
