How to save over extracted coffee made using Dutch cold brew method? My wife and I have just started using our Dutch Coffee Maker.

Our virgin experience was quite a failure.

We had some ground coffee (given to us as a gift) that was too fine (espresso grind), and the coffee came out over extracted.

What can we do to save the over extracted coffee? We do not want to throw it away :(

Thanks in advance!

PS: Can we get a dutch-coffee tag? Cold brew is not quite dutch :) or maybe enlighten me on which tags I should use. Thanks!
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!
