There are two types of people out there: those who don’t like coffee and those who are completely and obsessed with it. In case you brewed some coffee and realized that it tastes more bitter than usual, you can safely add some eggshells to your coffee filter instead of throwing out the bitter beans.
Just crush some of them and place them in the bottom of the coffee filter, one layer can absorb the bitter acids in the coffee. This trick will help you save a few dollars because one eggshell can be used for every 5/6 cups.
