What is the difference between Carafa III and Carafa Special III? I always thought they were the same thing, but after visiting the Weyermann website, I think I'm wrong about that. I have a stout recipe on deck, which includes some of the normal (i.e. non-special) carafa III, and ordered grains from Morebeer. Morebeer only offers carafa special III, so that's what I got. Are they interchangeable?
