Most coffee tastes like burnt vegetable farts. I think it's the process and that to get the most caffeine out, you have to over-roast it or something so that it's the most porous. Or they do that so that it's fast. I dunno. Vita coffee has a decent decaf with the orange label. Not great, just decent. I had to grind it finer than other coffees and pull slower shots.
