i made a wheat beer with a lot of chocolate malt with the idea of it being a chocolatey wheat beer, but now im liking the idea even more and i want to add actual melted chocolate into the carboy. has anyone done this, adding chocolate into the secondary fermentation? will it just harden and fall to the bottom or will it mix with the beer? should i use unsweetened chocolate or sweetened? or should i not do it at all?
