fwiw, DuClaw in Maryland makes a Stout by adding a Chocolate Raspberry Coffee to the grain bill in their Naked Fish. This was something I liked enough to fill a growler/keg with and put on my tap. It's on my bucket list of clones to make.
If you are looking for a big fresh raspberry flavor, not this beer. This one is more like a nice surprise find when you reach into the box of chocolates. For me, I don't like big fruit flavors in my beer, but really like the balance when it's an accent that enhances the other flavors. Chocolate and coffee are, IMO, a great compliment here.
Anyway, gourmet coffee intrigues me as a way to add raspberry.
