Hi WV, Curious how your blend will go. I have never tried such a combo. I am careful with Colombians as some are very acidic with lemon and grapefruit overtones. I have a red bourbon honey processed Colombian which has been excellent as a SO espresso. It took me a few goes to get it right, but it was worth the effort. It is also very nice roasted lighter for filter coffee. Another favourite of mine is a Red Honey processed Costa Rica coffee (CoopeTarrazu TE). This has been very easy to roast (similar to the Colombian), and is excellent on its own. I have added Indos and others to it, by way of an experiment, but it was perfect as a Single Origin. Let us know how it turns out.
