Add the apples, water, and spices to the slow cooker.
Cook for 4 hours on medium in a slow cooker. If your slow cooker only has “high” or “low”, cook on low for 6 hours.
When finished, mash the apples with a potato masher and cook for 30 more minutes on low.
Let cool a little bit and then strain carefully.
Discard the solids and enjoy the cider!
It can be kept in the fridge and heated up right before serving.
