title_body: How to save over extracted coffee made using Dutch cold brew method?
upvoted_answer: Well, when you are talking about cold-brewing methods, you will always want coarse ground coffee. If you are set on using this finely ground coffee in your Dutch Coffee Brewer you will want to try a few things.
  
  First, use much less coffee. Yes, it will still over extract over the same time period but will not be as strong. This is probably the worst option.
  
  Second, brew faster. I know that in a Dutch Brewer this is more complicated than just letting it sit for less time. If there is a way to put more water through the grounds in less time, you will want to go with that.
  
  Otherwise, use a different brew method for the finely ground coffee and buy new coffee for your Dutch brewer.
  
  Hope this helps!
