title_body: Custom hot drinks maker availability
upvoted_answer: As far as I know, there are commercial automats (machines) that can prepare custom defined hot beverages from granules or beans. (I have never seen one that can properly brew tea, though.) They can add milk powder or milk. Furthermore, those automats can even put a stick to stir the sugar at the end. There exist also small sizes that can fit onto a kitchen desk.
  
  However, I'm not sure if this is the gadget that you desire.
