    We are brewing a stout and, just out of curiosity, were wondering if the caffeine inherent in chocolate burns off during the boil?

    I've wondered the same. But I usually toss my coffee in while whirlpooling after it's below 150 so as to avoid harshness from it, so I've always assumed that the caffeine makes it into the final product. The only thing I was thinking was that perhaps it might be stripped out by fermentation, so I have no idea. Sciency folks?

    I'm pretty sure caffeine does not evaporate or boil away.

    I believe that caffeine will remain regardless of boil.

    Side Note:
    From my own experience I like to add chocolate in the secondary.

    Fermentation also will not be a way of getting rid of caffeine...as yeast only eats fermentable sugars. If adding cocoa nibs or coffee, end of boil (flavor/aroma) or post primary fermentation (secondary/bottling) are the preferred method. Not sure this is to topic....Prost!

    Be careful about that promiscuous caffeine consumption.

    Roasting lowers the caffeine level somewhat in coffee (dark roasted coffees tend to be lower caffeine), but I think high heat is necessary for that -- the boil won;t doi it. But consider that the caffeine level in your chocolate beer is not likely to cause any problems except for the most sensitive people.
