Hey everyone! Here lately, I've noticed that I've been making fantastic IPA's and pale ales, but my stouts are far from great! In several stout's I've brewed, I have gotten no roasted flavor, but a very unpleasant taste that can only be described as "twang"n or harsh. What is going on here? I have done a RIS with a ton of roasted barley, chocolate, and black patent and zero roast! Any help is much appreciated!
