If you don't want to freeze your brewed coffee, you can pour the rest of the pot into a carafe and place it in the refrigerator. Holding the coffee cold retains its taste and aroma outside the two-hour window. Experts say that you can refrigerate coffee for up to a week and recommend three to four days in the refrigerator. You can even reheat it from the refrigerator, but it won't taste as good as a freshly brewed cup.
