At the suggestion of UncleBeanz, I tried roasting 1/2 and 1/2 med and dark roast of the same coffee and mixing. Results were very good. SM's Moka Kadir at 1/2 FC-1/2 Vienna is chocolatey, with fruit, ultra smooth, dark roast flavors. UB's Negrita 1/2 city+, 1/2 FC+ is nutty, chocolatey, not as bold, excellent. 2 different coffees to start my Saturday, it's gonna be a good day
