I'm being tasked to make a coffee stout for my next batch, by holy decree of SWMBO. But along these lines I got to thinking about how coffee can reach across from stouts into other styles.
What struck me was trying to make a bitter where the bulk of the bitterness comes from coffee and not hops - to the extent of only using hops for mid to late additions.
Coffee comes across as astringent if you boil the grounds rather than steeping at less than boiling temperatures. I think if I could add the right amount of whole beans as a 60 minute addition then I could take on the bitterness/astringency while boiling off the bad flavor/aroma. Hops are added for 30 min and 0 min additions.
Then as I chill the wort into the 160F range I could toss ground coffee in as if I were making a legit cup of coffee at the right temperature where flavor dominates over bitterness.
Has there been any work to assign IBU to bitter additives that aren't hops? It'd be great to have at least some rough numbers to work off with a recipe like this that needs a pretty solid balance.
