title_body: how to make French Press coffee the right way?
upvoted_answer: Is it possible that you read a few posts on the Internet the wrong way?
  
  
  The grounds will not disappear, if anything they will appear "more", volume-wise because they swell in the hot water.
  There are two points about "grounds on the bottom":
  
  
  In the bottom of your cup, indicating a too fine grind of the beans or a hole in the filter mesh. Some very fine "dust" is ok, though. This is french press, not filtered coffee.
  Coffee sitting on the grounds after pushing the plunger for too long can negatively influence the taste of the last cup, making it excessively bitter, for example. So drink / pour the coffee shortly after you finished brewing. The time threshold depends on your beans and personal taste.
