Hey there.  I'm looking to soup up a coopers stout kit with some specialty grain.  what kinds of specialty grains would you recommend me to use?  I guess the amount of grain just depends on how strong i want the beer to end up?


   Cheers!

My first thought would be to add chocolate if you want it more stoutie. Probably about 1/2kg.

Let me know how it
