Hi, I also can relish a good ale with a coffee or chocolate twist in it. Recently brewed a Belgian ale (5.6% vol, 32 ibu, 36 etc) and added 2,5% chocolate malt (900 ebc) to the regular grains. In a previous batch I added about 10%, but that tends to override the overall taste of the ale. I'll have to wait another month though before I can taste the new brew. It's fermenting right now on a safbrew t-58.
