How Long Can You Keep Brewed Coffee?
You can store brewed coffee in your refrigerator for up to one week. Store the brewed coffee in a tightly sealed container to keep out any of the flavors or odors from the other items you are storing in your refrigerator.
Cold-brewed iced coffee concentrate may be stored for a longer period of time. You can prepare a cold-brewed concentrated coffee up to two weeks before you plan to serve iced coffee, and store it in your refrigerator until you need it. Then, when you are ready to serve it, add milk or water and ice cubes to each glass of iced coffee.
