Attempt #1 was just Brazil and Sumatra. It's a rather nutty Brazilian coffee which was overpowering the flavor profile. I wanted something a little darker and a little sweeter, so the Sulawesi and an adjustment in the Brazil so it's mostly medium roast but a little dark roast got me the darker roast flavor, while switching a little of the Sumatran coffee for just a tiny bit of a light Ethiopian coffee brought up the sweetness. Those changes helped tame the nuttiness.
