I roasted up the other week a blend, which you could say is a Mocca java but I added a little MM for some punch. Very impressed with the blend and it will be a keeper for me! I note the MM was no added post roast and bag was cracked 10 days post roast. Blend is roughly in these ratios of Eth Yirg Konga:Sum Gayo Spec:MM, 42.5:42.5:15 Jonty
