If it's the Brewer's Best summer ale kit,all that's already in the small bag that came with it. It's the one with the bitter orange zest,lemon zest,& spices. Trust me,it's in there. That was my wife's 1st brew in her new BB ale pale I bought her for NHB's day. Added at the last 15 minutes of the boil gives a nice light flavor on the back.
If we do this one again,I'm going to steep all that dried stuff in the lil baggy before that 15 minute boil in some "tea temp" water. Should intensify those flavors to a more exceptable level,imho.
