I've worked with it quite a bit now.
It's a lovely coffee. One of the sweetest but still balanced single-origin shots I've had.
Some thoughts on it (fwiw)...
1 - I actually like it at a surprisingly low brew temp. I find that, to my taste, the best results are when I take it down to the point where there is a tiny hint of citrus sourness. This maximizes the (incredible) aromatics, brings out all the sugars and also tones the cocoa notes down a bit to something softer and less powdery.
2 - I've found my personal sweet spot is to go with a slight up-dose and then pull the shot at a full 2oz and around 28s. This optimizes (to my taste) the layered complexity of the coffee.
3 - The only negatives of the coffee I've found are that it's lost in larger milk drinks and it seems VERY sensitive to dirty machines (where you get a sort of "fish oil" taste in the cup).
It's right now my 3rd favorite Ecco espresso (after the La Maravilla and the Cachoeira Yellow Bourbon).
