And since you'll probably ask, I'll tell you right up front: I purchase high quality Arabica beans green (un-roasted) and then roast them to perfection at home using a fluid bed (hot air) roaster. It's the only way to get the absolute freshest, high quality, great tasting coffee. (And, the price per pound is equal to or better than any pre-roasted whole bean coffee in any store).
enjoy the coffee i drink. of course, ‘mediocre’ is an opinion that is incorrect.
