title_body: Completely reusable, stainless-steel, zero-waste Nespresso pods any good?
upvoted_answer: TL;DR:
  Depends if the coffee style matches the pod design.
  How a Nespresso machine works:
  
  pod put in the machine gets pierced on the upper side
  hot water is released into the pod
  pressure rises inside the pod
  due to high pressure a membrane burst at the bottom of the pod
  brewed coffee is released
  
  By modifying the membrane to burst at a higher or lower pressure, other flavors will be extracted from the coffee, like pour over and espresso.
