Three DP Ethiopians and a Yemen? Yeah, I could get on board with that. Maybe there was never any brazil. Wouldn't need it, the yemen will provide plenty of chocolates as should the E's.
To the OP
HAve you tried the Monkey? The Monkey blend was a go-to blend for me back when I was roasting all my coffee for espresso. I found it to be incredibly versatile without being boring. If I was roasting for shots, I would stop THE INSTANT anything of second crack was heard. Sometimes Id even jump the gun, thinking I heard a pop, but didnt. Thats OK. If I wanted to make Cappas, I would go into second a little bit. And that way made good shots too, not even close to being too dark. Just, the citrus hints I got at the lighter level worked nicely for straight shots.
Also, if you mix the monkey with a central, say Guatemala or Nicauragua, the added sweetness and brightness is a welcome touch.
Give it a try, see if it does it for you.
