Place all oat milk ingredients into a blender. Blend on high for 3 minutes.
Lay a piece of cheesecloth over a large bowl. Pour the oat milk over the cheesecloth to strain, being careful to collect the edges of the cloth so the milk doesn't pull the cloth down and spill out. Squeeze all the liquid from the cheesecloth.
You may want to run it through the cheesecloth twice if the first time doesn't remove all the oat sediment. This is up to you. Once should be sufficient.
Place in the fridge and shake well before using.
