I am wondering about your grain bill and hop selection on this one. The bottle of this ale states on the label that it uses only cascade hops in five different addtions. Additionally the label states that the unique character comes from biscuit and chocolate malts.
I find it very odd that your clone contains none of the ingrediants of the original, outside of the choco malt. Not that your bew doesn' t sound great, cause it does....but i don't think it is an accurate reproduction of the original.
