title_body: How to brew 1-3 servings of coffee with as little waste as possible?
upvoted_answer: You can always try a mesh pour over like this one. 
  
  
  
  Also teapot like the one you described seems like it would work as well will coarser grinds (like the one needed for a french press) but like a french press leaving the grinds for too long will result in an overextracted bitter coffee. But keeping that in mind, it seems totally usable. 
  
  Hope this is helpful
