I'm sure this question has been answered but why can't you use milk chocolate in beer. I see a ton of posts about unsweetened powder or cacao nibs but never some melted ghardelli chocolate
But you can use ghardelli 100% cacao melted for sure. If you are looking for the sweetness and mouthfeel, use a little lactose sugar. Its not fermentable so the sweetness lingers and it leaves creamy mouthfeel.
