Wee Heavy Recipe

Notes:
------
Remove one gallon of first runnings and boil down to a pint or two, then add back to boil).

I would probably simplfy a bit (drop the chocolate and aromatic) to let the caramelization star. I would also avoid chinook, they can be a bit rough which is not what you want in a wee heavy.

Other than that it looks great, good luck.
