i've been concocting a recipe for a chocolate porter with a rich chocolatey flavor profile, as a dessert beer, and all i see on any message board is the addition of cocoa nibs in the secondary (with a very wide variety of quantities and contact time).
i was wondering if anyone has used an instant hot cocoa powder at any point in the brewing process whether it was during the boil, secondary or bottling process, to achieve a sweet chocolatey profile. i'm speculating that the sweetness in those powders might be due to a fermentable sugar that doesn't translate to the finished brew. (maybe it would help to add some lactose sugar in the boil?)
any thoughts?
