I'm planning on brewing a small batch of the Hermann Holtropp Rochefort clone this weekend, but have realised that I don't have any Carafa special I. I do have special II and III. Rather than having to order some, am I right in thinking that I could just use a smaller quantity of the II or III to produce the same colour addition? Given that it only uses 50g to begin with, I can't see that being a problem.
What does the hive mind have to say on this?
