I have a question and this may be totally crazy. I am planning on doing an Imperial Stout this weekend and then doing a partigyle small stout afterwards. Do you think that I can leave the hop trub, which would contain aroma additions from the IS in the boil kettle and then boil the smaller stout on this with no bittering additions? Would the 60 min additions from the IS left in the kettle cause too much harshness or would it be ok? Alternatively I could just put my aroma additions in some panty hose or something and fish them out for the next batch. Theoretically most of their bittering potential should remain correct?
