title_body: What am I doing wrong when I do my pour-over?
upvoted_answer: You need to use a coarser grind.  You have grounds that are just the right size to block the mesh. Too small and they'll just pass through, making your coffee gritty.  Medium-sized and they'll block the mesh.  Large (coarse) enough, and coffee can flow around them.  Not too large: you won't be able to extract enough from the beans with this brewing method using very coarse grounds.
  
  How are you grinding now?  If you're using a blade grinder, you'll often get a large variety of grain sizes (from very fine to very coarse), which means those medium and fine grains will start to clog to holes, even if much of the grounds are coarse.  A burr grinder will give you more consistency.
  
  Personally, I would recommend a plastic or ceramic pour-over brewer, which uses a paper filter.  This method is much more forgiving.  Paper filters won't get clogged with medium grains, and fine grains won't pass through.  I can easily brew 8-16 ounces with my "single-cup" pour-over brewer.
  
  One last suggestion: Give your bloom more than 10 seconds!  60 seconds will give your grounds enough time to fully bloom and become ready for further brewing.
  
  Good luck!
