Arabica produces such a varied spectrum of cups, it’s really quite head scratching to hear you write off the entire species, yet still hear you drink robusta.
For specifics, its been a while since I tried it. I can seek out some to try again, if you want. I don't think it is as extreme as the "tastes like soap" reaction that many have on cilantro, but I'm growing to think it has to be similar.
