I haven't really seen much up here about this, but it's been on my mind for some time. I would like to add a coffee flavor to a beer, but I'm not sure how to go about it. Does anyone have any recipes? Some people have said to brew coffee and add to taste before fermentation, some have said to use whole bean or ground coffee. Any thoughts? I was thinking about using whole beans in the secondary, dry-hop style.
Also, any recommended types of coffee to use? Something bold and roasty, caramelly, slightly sweet? Something higher in acidity? I work for Starbucks, so I have pretty much an unlimited range of choices. Thanks all.
