Is it a waste of time to add coffee to a secondary when you cold brew it? After reading a few posts I decided to try adding a cup of cold brewed coffee to my porter. My intent was to add this to a secondary and then rack to keg after a week. But that seems like a waste since there are no beans to absorb. Now I'm thinking I should just save time and put the 1 cup of coffee in the keg and rack the porter on top. Any thoughts?
