@Fiddle What steps did you follow, and what were you expecting?
@Fiddle I recommend letting it sit for at least 12 minutes, push the plunger down, then pull the plunger up again, allowing it to sit another 3 minutes before pushing the plunger back down and pouring. The directions for 4 minutes are going to give you a very weak-tasting cup. Also do not expect it to be as strong as pot coffee, but the flavors should be more noticeable.
