Daterra makes about a dozen state blends. I do not believe the Bruzzi and Sweet are sold in the US. The Yellow Bourbon is used 100% for lighter roasted espresso, and as a blender. It is quite acidic for a Brazil and has orange/mandarin and cola nut flavors. I do not believe it is suitable for darker roasting.
My impression is that their different estate blends are designed specifically for different roast levels and blending purposes.
Daterra has a website; but it's one of those made in Italy, no information, flash nuisances; so I've linked you to their contact page.
Your best approach is to get whatever they have formulated for 100% use (if that is how you sell it) at the roast level you normally use.
