I've developed a taste for dark-roast coffee but have to switch to decaf, and although decaf coffee beans are widely available, I'm finding it difficult to locate a good decaf DARK roast. Graffeo decaf is good but not nearly dark enough. I'm beginning to think decaf espresso bean might be my best bet. I'm open to any & all advice! Would prefer to buy in person but will resort to mail order if necessary. Thanks!
