HOW LONG DOES FROZEN COFFEE LAST?
You can pour any leftover frozen coffee mixture into an ice cube tray, cover and keep in the freezer for up to about two weeks. When you’re ready to enjoy it, simply add the ice cubes and a little extra liquid to your blender and recreate your frozen coffee in seconds.
Make sure to cover the ice cube tray with an airtight top or put it in a freezer bag. Coffee can quickly absorb smells and flavors from other items in your freezer.
