Remove the core from the apple and chop into cubes. No need to peel the apples! Just core and chop
Add the cinnamon sticks, ginger, nutmeg, vanilla and brown sugar to the pot and toss together with the apples
Pour the water over the apples and place the lid on the Instant pot, close and make sure the steamer valve is set to “seal”. Press the “manual” button and set the timer for 15 minutes cooking time at high pressure. When the time is up, let the Instant Pot® naturally release the pressure inside. This means, just let it sit on your counter for another 15 minutes or so until you are able to unseal the lid (the Instant Pot® releases the lid lock when the pressure is fully released).
Pour the contents of the apple cider into a strainer over a large bowl. If you want your cider to be completely clear, just strain the fruit and discard, leaving behind a beautiful cider. If you would like a cider that is a little thicker, press some of the apples through the mesh strainer using the back of a ladle and mix with the juice.
Serve the cider hot or cold and store in the fridge for up to two weeks!
