What Are Coffees That Have Market Potential?

We are looking at coffees that have market potention. When i say market potential, what i mean is coffees that are acceptable and desirable to consumers. One of those is stenepila coffee, that's from west africa. That's a really interesting species because it has, whwee might say, a superior flavor. It tastes like high quality orabica. The downside witston afir is it's a low yielder. So we would work on that to try and improve yield.
