title_body: How to follow Aeropress instructions when water filters through too quickly
upvoted_answer: It sounds as though the pre-ground coffee you are using is not ground fine enough. Generally the more coarse the grind, the faster water will filter through.   You may try throwing some additional grind on your coffee, or buy pre-ground coffee that is more finely ground (although a snob such as myself would never actually advise buying pre-ground coffee).
