Add the oats and water to a blender and blend for 1 minute.
Strain the oat milk using a nut milk bag or cheesecloth and allow it to naturally strain. This process will take a few minutes. Do not press on the cheesecloth to force the oat milk out. This will result in a smoother oat milk.
Rinse the blender and pour the oat milk back in the blender. Add the cocoa, sugar, and salt. Blend for one minute. Taste and adjust the sugar levels to taste.
Pour the oat milk into a pitcher or bottle with a lid and store in the fridge.
Notes
To adjust the creaminess: We recommend adding a handful of nuts or seeds for creamier homemade oat milk. Increasing the oat-to-water ratio will just lead to slimy oat milk.
For the smoothest plant milk: Strain it twice or strain it through a very fine material, like a kitchen towel, to remove maximum sediment/starch.
To fortify homemade oat milk: Blend the contents of a supplement capsule into it (like vegan vitamin D, calcium, or B12).
