Food, Wine, Coffee, and Robotics

There now exists a Robot that has the sensory capability to pinpoint the region of any tasted wine, as well as to detect the subtle differences in terrior within subregions of that wine(sometimes a matter of a few miles.)
There also exists a Health and Food Advice Robot that can distinguish between thirty different kinds of wine, cheeses, and breads in order to give advice that reinforces healthy choices. And finally, there exists the prototype of a Robot that will cook you dinner.
Now, I have no qualms about letting one Robot offer me wine suggestions while another gives me health advice, and another cooks dinner. Nevertheless, I must ask the question, if scientists can do all of these things, why the hell have they yet to invent a Coffee Robot? I just don't understand!
