Lets talk about CC ... ive done a bit of reading but because its not as popular as Jim Beam etc , the grain bill is hard to find ,,, add the fact that because its a blended mix theres a good chance (well after my reading) that its blended with neutral but with a grain bill of at least 51% corn, maybe 10% rye, wheat and at least 10% barley.
my guess would be :
60% Corn
10% Rye
16% Wheat
14% Barley
Like i said , its just a guess and wouldnt mind getting some thoughts on it
